Difficulties with a more complex Business Rule Engine in Oracle SOA Suite
0In my previous post I’ve shown how to create a composite in the Oracle SOA Suite with a simple decision table in a Business Rule Engine component. For that post I had used quite a simple data model resulting in a small xml/xsd tree. For our project I wanted to repeat the exercise with the real data model, so a larger xml tree defined by multiple imported xsd files. Unfortunately it wasn’t as easy as I hoped for. In this second blog post about the Business Rule Engine I’ll show you about the difficulties I had and how I’ve solved them. (more…)
Cookbook creating Business Rule Engine with a simple Decision Table in Oracle SOA Suite
5For educational purposes I’ve created a cookbook in powerpoint format on how to create a simple decision table in Oracle SOA Suite with a Business Rule engine. To share this I’ve uploaded it to slideshare and post it here in the Amis blog as well. (more…)
Publishing the Product Details WebService based on an Excel based Product Catalog using the SOA Suite 11g File Adapter with Synchronous File Read
1On the one hand: the organization wants to publish a real Web Service, SOAP enabled and all. On the other: the data to be provided by this Web Service is maintained in Excel files and undergoes regular changes by people who are well versed in Excel but absolutely blank when it comes to Web Services.
This article demonstrates how the File Adapter can be used with a Composite application running in Oracle SOA Suite 11g to synchronously read from a file with product catalog details and return information about a single product for which the product identifier was sent to the service.
In just a few, largely declarative, steps, the bridge is built from file based article records to a real SOAP Web Service.
How to call a webservice directly from Java (without webservice library)
7In this blog I will show you how you can call a webservice programmatically in Java without using a webservice library like JAX-WS or Apache Axis. Normally you would use of course a webservice library, but in some cases this can be useful and quick; for example when you have problems generating a client proxy with a webservice library or if you only need some small specific parts of the SOAP response XML tree.  It shows that a SOAP call is just XML over HTTP, from a plain piece of Java code. Then, I will show you an example how you can use this and make your own servlet webservice-tester like a simple SoapUI in JDeveloper 11.1.1.3.
How to remove unwanted SOAP header elements in JAX-WS
0In our current webservice project with JAX-WS in  JDeveloper  11.1.1.3 we have a challenge with calling a webservice. This webservice from a remote organisation does not accept specific SOAP header elements our client application creates – although we followed the contract of the WSDL correctly. Of course this webservice must follow it as well as we have to, but for now we don’t have a choice but to make a workaround.  How can we remove unwanted elements from a SOAP header? In this blog I will show you how you can do that using a JAX-WS SOAPHandler that inspects the SOAP header and removes specific addressing elements. (more…)
Hands-on: Synchronize your database from a webservice with JAX-WS and ADF Business Components
0This step-by-step starter hands-on provides an example how to make a JAX-WS webservice proxy in JDeveloper, and save retrieved data from this webservice in a batch-job to your own database with ADF Business Components. Duration: 60 minutes. For this hands-on example, imagine that your company wants to expand internationally and that reliable, up to date country information is absolutely critical. Recently there were some changes in the number of countries and there might be in the future. Since 1990, 33 new countries have been created. A few months ago the world welcomed a new country (South-Sudan) and yet we don’t know what will happen in Libya (maybe it will be separated in West and East-Libya?). Your company wants to weekly synchronise its internal countries database table with up-to-date country information from a recognised country-monitoring institution that delivers up-to-date country information by a webservice.
Part 1 – Create the country webservice client with JAX-WSWe are going to create a webservice client proxy for a country webservice available on: (more…)
