Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX

At a public sector organization in the Netherlands there was the need to make an inventory of the deployed OSB services in order to find out, the dependencies with certain external web services (which were on a list to become deprecated).

For this, in particular the endpoints of business services were of interest.

Besides that, the dependencies between services and also the Message Flow per proxy service was of interest, in particular Operational Branch, Route, Java Callout and Service Callout actions.

Therefor an OSBServiceExplorer tool was developed to explore the services (proxy and business) within the OSB via WebLogic Server MBeans with JMX. For now, this tool was merely used to quickly return the information needed, but in the future it can be the basis for a more comprehensive one.

This article will explain how the OSBServiceExplorer tool uses WebLogic Server MBeans with JMX.

The code mentioned in this article is based on Oracle Service Bus 11.1.1.7.

If you are interested in general information about, using MBeans with JMX, I kindly point you to another article (written be me) on the AMIS TECHNOLOGY BLOG: “Oracle Service Bus : disable / enable a proxy service via WebLogic Server MBeans with JMX”, via url: https://technology.amis.nl/2017/02/28/oracle-service-bus-disable-enable-a-proxy-service-via-weblogic-server-mbeans-with-jmx/

Remark: Some names in the examples in this article are in Dutch, but don’t let this scare you off.

MBeans

For ease of use, a ms-dos batch file was created, using MBeans, to explore services (proxy and business). The WebLogic Server contains a set of MBeans that can be used to configure, monitor and manage WebLogic Server resources.

On a server, the ms-dos batch file “OSBServiceExplorer.bat” is called.

The content of the ms-dos batch file “OSBServiceExplorer.bat” is:
java.exe -classpath “OSBServiceExplorer.jar;com.bea.common.configfwk_1.7.0.0.jar;sb-kernel-api.jar;sb-kernel-impl.jar;wlfullclient.jar” nl.xyz.osbservice.osbserviceexplorer. OSBServiceExplorer “xyz” “7001” “weblogic” “xyz”

In the ms-dos batch file via java.exe a class named OSBServiceExplorer is being called. The main method of this class expects the following parameters:

Parameter name Description
HOSTNAME Host name of the AdminServer
PORT Port of the AdminServer
USERNAME Username
PASSWORD Passsword

In the sample code shown at the end of this article, the use of the following MBeans can be seen:

Provides a common access point for navigating to all runtime and configuration MBeans in the domain as well as to MBeans that provide domain-wide services (such as controlling and monitoring the life cycles of servers and message-driven EJBs and coordinating the migration of migratable services). [https://docs.oracle.com/middleware/1213/wls/WLAPI/weblogic/management/mbeanservers/domainruntime/DomainRuntimeServiceMBean.html]

This library is not by default provided in a WebLogic install and must be build. The simple way of how to do this is described in “Fusion Middleware Programming Stand-alone Clients for Oracle WebLogic Server, Using the WebLogic JarBuilder Tool”, which can be reached via url: https://docs.oracle.com/cd/E28280_01/web.1111/e13717/jarbuilder.htm#SACLT240.

Provides methods for retrieving runtime information about a server instance and for transitioning a server from one state to another. [https://docs.oracle.com/cd/E11035_01/wls100/javadocs_mhome/weblogic/management/runtime/ServerRuntimeMBean.html]

Provides various API to query, export and import resources, obtain validation errors, get and set environment values, and in general manage resources in an ALSB domain. [https://docs.oracle.com/cd/E13171_01/alsb/docs26/javadoc/com/bea/wli/sb/management/configuration/ALSBConfigurationMBean.html]

Once the connection to the DomainRuntimeServiceMBean is made, other MBeans can be found via the findService method.

Service findService(String name,
                    String type,
                    String location)

This method returns the Service on the specified Server or in the primary MBeanServer if the location is not specified.

In the sample code shown at the end of this article, certain java fields are used. For reading purposes the field values are shown in the following table:

Field Field value
DomainRuntimeServiceMBean.MBEANSERVER_JNDI_NAME weblogic.management.mbeanservers.domainruntime
DomainRuntimeServiceMBean.OBJECT_NAME com.bea:Name=DomainRuntimeService,Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean
ALSBConfigurationMBean.NAME ALSBConfiguration
ALSBConfigurationMBean.TYPE com.bea.wli.sb.management.configuration.ALSBConfigurationMBean
Ref.DOMAIN <Reference to the domain>

Because of the use of com.bea.wli.config.Ref.class , the following library <Middleware Home Directory>/Oracle_OSB1/modules/com.bea.common.configfwk_1.7.0.0.jar was needed.

A Ref uniquely represents a resource, project or folder that is managed by the Configuration Framework.

A special Ref DOMAIN refers to the whole domain.
[https://docs.oracle.com/cd/E17904_01/apirefs.1111/e15033/com/bea/wli/config/Ref.html]

Because of the use of weblogic.management.jmx.MBeanServerInvocationHandler.class , the following library <Middleware Home Directory>/wlserver_10.3/server/lib/wlfullclient.jar was needed.

When running the code the following error was thrown:

java.lang.RuntimeException: java.lang.ClassNotFoundException: com.bea.wli.sb.management.configuration.DelegatedALSBConfigurationMBean
	at weblogic.management.jmx.MBeanServerInvocationHandler.newProxyInstance(MBeanServerInvocationHandler.java:621)

Process exited.

So because of the use of com.bea.wli.sb.management.configuration.DelegatedALSBConfigurationMBean.class the following library <Middleware Home Directory>/Oracle_OSB1/lib/sb-kernel-impl.jar was also needed.

Runtime information (name and state) of the server instances

The OSBServiceExplorer tool writes its output to a text file called “OSBServiceExplorer.txt”.

First the runtime information (name and state) of the server instances (Administration Server and Managed Servers) of the WebLogic domain are written to file.

Example content fragment of the text file:

Found server runtimes:
- Server name: AdminServer. Server state: RUNNING
- Server name: ManagedServer1. Server state: RUNNING
- Server name: ManagedServer2. Server state: RUNNING

See the code fragment below:

fileWriter.write("Found server runtimes:\n");
int length = (int)serverRuntimes.length;
for (int i = 0; i < length; i++) {
    ServerRuntimeMBean serverRuntimeMBean = serverRuntimes[i];

    String name = serverRuntimeMBean.getName();
    String state = serverRuntimeMBean.getState();
    fileWriter.write("- Server name: " + name + ". Server state: " +
                     state + "\n");
}
fileWriter.write("" + "\n");

List of Ref objects (projects, folders, or resources)

Next, a list of Ref objects is written to file, including the total number of objects in the list.

Example content fragment of the text file:

Found total of 1132 refs, including the following proxy and business services: 
…
- ProxyService: JMSConsumerStuFZKNMessageService-1.0/proxy/JMSConsumerStuFZKNMessageService_PS
…
- ProxyService: ZKN ZaakService-2.0/proxy/UpdateZaak_Lk01_PS
…
- BusinessService: ZKN ZaakService-2.0/business/eBUS/eBUS_FolderService_BS

See the code fragment below:

Set refs = alsbConfigurationMBean.getRefs(Ref.DOMAIN);


fileWriter.write("Found total of " + refs.size() + " refs, including the following proxy and business services:\n");

for (Ref ref : refs) {
    String typeId = ref.getTypeId();

    if (typeId.equalsIgnoreCase("ProxyService")) {

        fileWriter.write("- ProxyService: " + ref.getFullName() +
                         "\n");
    } else if (typeId.equalsIgnoreCase("BusinessService")) {
        fileWriter.write("- BusinessService: " + ref.getFullName() +
                         "\n");
    } else {
        //fileWriter.write(ref.getFullName());
    }
}

fileWriter.write("" + "\n");

As mentioned before, a Ref object uniquely represents a resource, project or folder. A Ref object has two components:

  • typeId that indicates whether it is a project, folder, or a resource
  • array of names of non-zero length.

For a resource the array of names start with the project name, followed by folder names, and end with the resource name.
For a project, the Ref object simply contains one name component, that is, the project name.
A Ref object for a folder contains the project name followed by the names of the folders which it is nested under.

[https://docs.oracle.com/cd/E17904_01/apirefs.1111/e15033/com/bea/wli/config/Ref.html]

Below is an example of a Ref object that represents a folder (via JDeveloper Debug):

ResourceConfigurationMBean

In order to be able to determine the actual endpoints of the proxy services and business services, the ResourceConfigurationMBean is used. When connected, the Service Bus MBeans are located under com.oracle.osb. [https://technology.amis.nl/2014/10/20/oracle-service-bus-obtaining-list-exposed-soap-http-endpoints/]

When we look at the java code, as a next step, the names of a set of MBeans specified by pattern matching are put in a list and looped through.

Once the connection to the DomainRuntimeServiceMBean is made, other MBeans can be found via the queryNames method.

Set queryNames(ObjectName name,
               QueryExp query)
               throws IOException

Gets the names of MBeans controlled by the MBean server. This method enables any of the following to be obtained: The names of all MBeans, the names of a set of MBeans specified by pattern matching on the ObjectName and/or a Query expression, a specific MBean name (equivalent to testing whether an MBean is registered). When the object name is null or no domain and key properties are specified, all objects are selected (and filtered if a query is specified). It returns the set of ObjectNames for the MBeans selected.
[https://docs.oracle.com/javase/7/docs/api/javax/management/MBeanServerConnection.html]

See the code fragment below:

String domain = "com.oracle.osb";
String objectNamePattern =
    domain + ":" + "Type=ResourceConfigurationMBean,*";

Set osbResourceConfigurations =
    connection.queryNames(new ObjectName(objectNamePattern), null);

fileWriter.write("ResourceConfiguration list of proxy and business services:\n");
for (ObjectName osbResourceConfiguration :
     osbResourceConfigurations) {
…
    String canonicalName =
        osbResourceConfiguration.getCanonicalName();
    fileWriter.write("- Resource: " + canonicalName + "\n");
…
}

The pattern used is: com.oracle.osb:Type=ResourceConfigurationMBean,*

Example content fragment of the text file:

ResourceConfiguration list of proxy and business services:
…
- Resource: com.oracle.osb:Location=AdminServer,Name=ProxyService$ZKN ZaakService-2.0$proxy$UpdateZaak_Lk01_PS,Type=ResourceConfigurationMBean
…

Below is an example of an ObjectName object (via JDeveloper Debug), found via the queryNames method:

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 3

Via the Oracle Enterprise Manager Fusion Middleware Control for a certain domain, the System MBean Browser can be opened. Here the previously mentioned ResourceConfigurationMBean’s can be found.

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 4
[Via MBean Browser]

The information on the right is as follows (if we navigate to a particular ResourceConfigurationMBean, for example …$UpdateZaak_Lk01_PS) :

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 5
[Via MBean Browser]

Here we can see that the attributes Configuration and Metadata are available:

  • Configuration

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 6

[Via MBean Browser]

The Configuration is made available in java by the following code fragment:

CompositeDataSupport configuration = (CompositeDataSupport)connection.getAttribute(osbResourceConfiguration,"Configuration");
  • Metadata

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 7

[Via MBean Browser]

The Metadata is made available in java by the following code fragment:

CompositeDataSupport metadata = (CompositeDataSupport)connection.getAttribute(osbResourceConfiguration,"Metadata");

Diving into attribute Configuration of the ResourceConfigurationMBean

For each found proxy and business service the configuration information (canonicalName, service-type, transport-type, url) is written to file.

See the code fragment below:

String canonicalName =
    osbResourceConfiguration.getCanonicalName();
…
String servicetype =
    (String)configuration.get("service-type");
CompositeDataSupport transportconfiguration =
    (CompositeDataSupport)configuration.get("transport-configuration");
String transporttype =
    (String)transportconfiguration.get("transport-type");
…
fileWriter.write("  Configuration of " + canonicalName +
                 ":" + " service-type=" + servicetype +
                 ", transport-type=" + transporttype +
                 ", url=" + url + "\n");

Proxy service configuration:

Below is an example of a proxy service configuration (content fragment of the text file):

  Configuration of com.oracle.osb:Location=AdminServer,Name=ProxyService$ZKN ZaakService-2.0$proxy$UpdateZaak_Lk01_PS,Type=ResourceConfigurationMBean: service-type=Abstract SOAP, transport-type=local, url=local

The proxy services which define the exposed endpoints, can be recognized by the ProxyService$ prefix.

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 8
[Via MBean Browser]

For getting the endpoint, see the code fragment below:

String url = (String)transportconfiguration.get("url");

Business service configuration:

Below is an example of a business service configuration (content fragment of the text file):

  Configuration of com.oracle.osb:Location=AdminServer,Name=BusinessService$ZKN ZaakService-2.0$business$eBUS$eBUS_FolderService_BS,Type=ResourceConfigurationMBean: service-type=SOAP, transport-type=http, url=http://xyz/eBus/FolderService.svc

The business services which define the exposed endpoints, can be recognized by the BusinessService$ prefix.

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 9
[Via MBean Browser]

For getting the endpoint, see the code fragment below:

CompositeData[] urlconfiguration =
    (CompositeData[])transportconfiguration.get("url-configuration");
String url = (String)urlconfiguration[0].get("url");

So, via the url key found in the business service configuration, the endpoint of a business service can be found (for example: http://xyz/eBus/FolderService.svc). So in that way the dependencies (proxy and/or business services) with certain external web services (having a certain endpoint), could be found.

Proxy service pipeline, element hierarchy

For a proxy service the elements (nodes) of the pipeline are investigated.

See the code fragment below:

CompositeDataSupport pipeline =
    (CompositeDataSupport)configuration.get("pipeline");
TabularDataSupport nodes =
    (TabularDataSupport)pipeline.get("nodes");

[Via MBean Browser]

Below is an example of a nodes object (via JDeveloper Debug):

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 11

If we take a look at the dataMap object, we can see nodes of different types.

Below is an example of a node of type Stage (via JDeveloper Debug):

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 12

Below is an example of a node of type Action and label ifThenElse (via JDeveloper Debug):

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 13

Below is an example of a node of type Action and label wsCallout (via JDeveloper Debug):

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 14

For the examples above the Message Flow part of the UpdateZaak_Lk01_PS proxy service looks like:

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 15

The mapping between the node-id and the corresponding element in the Messsage Flow can be achieved by looking in the .proxy file (in this case: UpdateZaak_Lk01_PS.proxy) for the _ActiondId- identification, mentioned as value for the name key.

<con:stage name="EditFolderZaakStage">
        <con:context>
          …
        </con:context>
        <con:actions>
          <con3:ifThenElse>
            <con2:id>_ActionId-7997641858449402984--36d1ada1.1562c8caabd.-7c84</con2:id>
            <con3:case>
              <con3:condition>
                …
              </con3:condition>
              <con3:actions>
                <con3:wsCallout>
                  <con2:id>_ActionId-7997641858449402984--36d1ada1.1562c8caabd.-7b7f</con2:id>
                  …

The first node in the dataMap object (via JDeveloper Debug) looks like:

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 16

The dataMap object is of type HashMap. A hashMap maintains key and value pairs and often denoted as HashMap<Key, Value> or HashMap<K, V>. HashMap implements Map interface

As can be seen, the key is of type Object and the value of type CompositeData.

In order to know what kind of information is delivered via the CompositeData object, the rowType object can be used.

See the code fragment below:

TabularType tabularType = nodes.getTabularType();
CompositeType rowType = tabularType.getRowType();

Below is an example of a rowType object (via JDeveloper Debug):

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 17

From this it is now clear that the CompositeData object for a ProxyServicePipelineElementType contains:

Index key value
0 children Children of this node
1 label Label
2 name Name of the node
3 node-id Id of this node unique within the graph
4 type Pipeline element type

In the code fragment below, an iterator is used to loop through the dataMap object.

Iterator keyIter = nodes.keySet().iterator();

for (int j = 0; keyIter.hasNext(); ++j) {

    Object[] key = ((Collection)keyIter.next()).toArray();

    CompositeData compositeData = nodes.get(key);

    …
}

The key object for the first node in the dataMap object (via JDeveloper Debug) looks like:

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 18

The value of this key object is 25, which also is shown as the value for the node-id of the compositeData object, which for the first node in the dataMap object (via JDeveloper Debug) looks like:

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 19

It’s obvious that the nodes in the pipeline form a hierarchy. A node can have children, which in turn can also have children, etc. Think for example of a “Stage” having an “If Then” action which in turn contains several “Assign” actions. A proxy service Message Flow can of course contain all kinds of elements (see the Design Palette).

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 20

Below is (for another proxy service) an example content fragment of the text file, that reflects the hierarchy:

     Index#76:
       level    = 1
       label    = branch-node
       name     = CheckOperationOperationalBranch
       node-id  = 62
       type     = OperationalBranchNode
       children = [42,46,50,61]
         level    = 2
         node-id  = 42
         children = [41]
           level    = 3
           label    = route-node
           name     = creeerZaak_Lk01RouteNode
           node-id  = 41
           type     = RouteNode
           children = [40]
             level    = 4
             node-id  = 40
             children = [39]
               level    = 5
               label    = route
               name     = _ActionId-4977625172784205635-3567e5a2.15364c39a7e.-7b99
               node-id  = 39
               type     = Action
               children = []
         level    = 2
         node-id  = 46
         children = [45]
           level    = 3
           label    = route-node
           name     = updateZaak_Lk01RouteNode
           node-id  = 45
           type     = RouteNode
           children = [44]
             level    = 4
             node-id  = 44
             children = [43]
               level    = 5
               label    = route
               name     = _ActionId-4977625172784205635-3567e5a2.15364c39a7e.-7b77
               node-id  = 43
               type     = Action
               children = []
         …

Because of the interest in only certain kind of nodes (Route, Java Callout, Service Callout, etc.) some kind of filtering is needed. For this the label and type keys are used.

See the code fragment below:

String label = (String)compositeData.get("label");
String type = (String)compositeData.get("type");

if (type.equals("Action") &&
    (label.contains("wsCallout") ||
     label.contains("javaCallout") ||
     label.contains("route"))) {

    fileWriter.write("    Index#" + j + ":\n");
    printCompositeData(nodes, key, 1);
} else if (type.equals("OperationalBranchNode") ||
           type.equals("RouteNode"))
{
    fileWriter.write("    Index#" + j + ":\n");
    printCompositeData(nodes, key, 1);
}

Example content fragment of the text file:

    Index#72:
       level    = 1
       label    = wsCallout
       name     = _ActionId-7997641858449402984--36d1ada1.1562c8caabd.-7b7f
       node-id  = 71
       type     = Action
       children = [66,70]
    Index#98:
       level    = 1
       label    = wsCallout
       name     = _ActionId-7997641858449402984--36d1ada1.1562c8caabd.-7997
       node-id  = 54
       type     = Action
       children = [48,53]
    Index#106:
       level    = 1
       label    = wsCallout
       name     = _ActionId-7997641858449402984--36d1ada1.1562c8caabd.-7cf4
       node-id  = 35
       type     = Action
       children = [30,34]

When we take a closer look at the node of type Action and label wsCallout with index 106, this can also be found in the MBean Browser:

Oracle Service Bus : Service Exploring via WebLogic Server MBeans with JMX lameriks 201703 21
[Via MBean Browser]

The children node-id’s are 30 (a node of type Sequence and name requestTransform, also having children) and 34 (a node of type Sequence and name responseTransform, also having children).

Diving into attribute Metadata of the ResourceConfigurationMBean

For each found proxy service the metadata information (dependencies and dependents) is written to file.

See the code fragment below:

fileWriter.write("  Metadata of " + canonicalName + "\n");

String[] dependencies =
    (String[])metadata.get("dependencies");
fileWriter.write("    dependencies:\n");
int size;
size = dependencies.length;
for (int i = 0; i < size; i++) {
    String dependency = dependencies[i];
    if (!dependency.contains("Xquery")) {
        fileWriter.write("      - " + dependency + "\n");
    }

By looking at the results in the text file "OSBServiceExplorer.txt", the dependencies between services (proxy and business) and also the dependencies with certain external web services (with a particular endpoint) could be extracted.

Example content of the text file:
