Create a JasperReport from Oracle BPEL
Feb 5th
In my previous post I described how to create a Report (CDBooklet) with JasperReport in Java.
Follow this link to take a look at the post ‘Using Java to create a report with the JasperReport java API’
For this new post I created a webservice wrapper around this reporting functionality and deployed it to a Weblogic application server.
Here I will describe how to create a CDBooklet report with the Oracle SOA Suite 11g.
First we have to determine the in- and output payload for the service. You can find a detailed description of this service in my previous post.

Using Java to create a report with the JasperReport java API
Jan 15th
In this blog I will describe how to create a Report with JasperReport in Java. For this purpose I have used the Communitie edition of iReport. This edition contains besides JasperReport also iReport. iReport is a report designer for JasperReport. You can download it from http://jasperforge.org/projects/ireport
After installation I started iReport to design a report. I have design a report to create CD booklets. It contains the name of the artist, an album title, an image, the tracklist and the lyrics of these tracks.
Business Validation in Oracle SOA Suite 11g using Schematron
Jan 5th
In a previous post I’ve explained the Schematron standard, how it works and how to use it. In the Oracle SOA Suite you can ‘Validate Semantic’ on the input (request) of a routing rule in a Mediator component by selecting a Schematron file. This is the Schemtron xml file in which you define your validation rules. The SOA Suite takes care of applying them on the request by executing the double transformation.
However, to be able to get the Schematron file working you need to declare the namespaces of the input message and rewrite a report rule to an assert rule. In this post I will show you how to do this with the same business rules (so the same Schematron rules and Schematron file) as the last example in a previous blog explaining Schematron.

Using the Oracle XMLDB Repository to Automatically Shred Windows Office Documents (Part 1)
Dec 20th
People who have attended the UKOUG presentation this year where Mark Drake, Sr. Product Manager XML Technologies / XMLDB, Oracle HQ, and I demonstrated the first principles of the XDB Repository, might have been impressed with its (GEO/KML Spatial, Image EXIF info) capabilities combined with Google Earth. This post will zoom in on how to consume automatically content of Windows Office document (docx).

Most (APEX) people know the PL/SQL Gateway functionality of the XDB Protocol Listener, but this is only one very small part of the XDB Repository functionality. To be precise only one “servlet” part of it. Those “servlets” can be based on Java, C or PL/SQL. The PL/SQL Gateway, as it’s name suggests, is based on the PL/SQL part. Another “servlet”, the Native Database Web Service (NDWS), which enables you to create a database SOA endpoint service and more, is based on C code. Beside demonstrating the WebDAV ACL driven security features and database extensibility/interfacing facilities based on the database (no cost option) XMLDB functionality, it also explain one of the coolest features, IMHO, introduced in Oracle 11gR1 called: XDB Repository Events.
There is one big problem in all of this. It is very, very sparsely documented and although there is some, or was some, code out there on the worldwide web, it took me a while to get a feeling of all the specifics at hand. This post will extend on some of the posts I already created to give to a head start of what is possible. This post will demonstrate what you can do with Windows Office documents, nowadays embedded (zipped) XML content, with extentions called: docx, xlsx or pptx…
UKOUG 2011 – Drag, Drop and other Stuff. Using your Database as a File Server
Dec 12th
Last Thuesday, Mark Drake, Senior Product Manager and I, delivered a good presentation during UKOUG in Birmingham about how to use your database, via XMLDB functionality, as a file server. The presentation demonstrated as well how you could extent the “standaard” file server (aka your database) functionality with features like, WebDAV driven ACL Security and XDB Repository Events, which enable you to automatically trigger event driven actions based on, for example, file naming, content, creator or others.
You can find the presentation on Slideshare or enjoy it here.

During the demonstration in the second half of the presentation, we demonstrated how you can automatically consume the EXIF and KML information embedded in pictures to use it with the Google Earth API. All the code used for this Google Earth demonstration, and more, can be found on the Oracle XMLDB Sample Code page.
Have fun trying it out and if there any questions, post them on the OTN Oracle XMLDB forum.
Absolutely Typical – The whole story on Types and how they power PL/SQL Interoperability (UKOUG, 2011)
Dec 12th
This presentation will hopefully convince database developers that types in the Oracle Database are worth their salt – and more. With the recent improvements in 11gR2, the pieces are available to complete the puzzle of structured and modern programming with a touch of OO and more importantly to create a decoupled, reusable API that exposes services based on tables and views to clients that speak SQL, AQ, PL/SQL, Types, XML or RESTful, through SQL*Net, JDBC or HTTP.
This session shows through many demonstrations how types and collections are defined, how they are used between SQL and PL/SQL and how they can be converted to and from XML and JSON and how they drive Native WebServices as well as RESTful services based on the Embedded PL/SQL Gateway. Everyone doing PL/SQL programming will benefit immediately from this session. Every Database Developer should be aware of Types and Collections. For structured programming, for optimal SQL to PL/SQL integration and for interoperability to client application. This session introduces Types and Collections, their OO capabilities, the conversion to XML and JSON, their use in Native and RESTful WebServices and the pivotal role they can play in encapsulation and decoupling.
The slides can be reviewed here:

WebLogic 12c released!
Dec 2nd
At December the 1st, 2011, Oracle announced it’s new major release, the 12c release. As Oracle added the i (internet) at its 8 release, the g(gridcomputing) at its 10 release, now the focus will be on the c(cloudcomputing).
Many new features come out of the fact that Oracle has made its key application server ready for the cloud, that is, ready for to run on enigineered systems, in fact its own Exalogic machine, Oracle’s solution for implementing the cloud.
So let’s take a look what this new release brings us, in this blogpost. There are several new features available in the 12c
New or enhanced WebLogic 12c features
- JAVA EE 6 support all kinds of JEE6 specifications are implemented like :
- JSF 2.0,Java Servlets 3.0 JPA 2.0 and EJB 3.1.
- Managed Beans 1.0
- WebLogic 12c also supports supports Java SE 7 (and Java SE 6).
- Java language optimizations and Internationalization
- Client and server support
- SSL/TLS 1.2 in JSSE to support JAVA Socket Transport security
- Converged Java VM:JRockit and HotSpot are incorporated with the best features from both.The JVM convergence will be a multi-year process, which was confirmed during my presence at Oracle’s Publisher Seminar 2011 during OOW
I won’t discuss the full list in this blog because there’s more about WebLogic than only (although very important of course!) the JAVA EE 6 specifications.
- Support for IDE’s. WebLogic already supported JDeveloper 11.1.1.5, but will come out with the 11.1.1.6 later on. Also suported are Eclipse and NetBeans 7.1 IDE. As said, the JDeveloper 11.1.1.6 and IntelliJIdea IDE will be supported in a later timeframe.
- New enhanced WebLogic Maven Plug-in See the various new options below in this scheme
UKOUG 2011: Using your Database as a Fileserver
Nov 21st
UKOUG 2011 is nearby and one of the coolest things in Oracle 11g and onwards is, IMHO, a functionality called XDB Repository Events. Most of you probably know that based on XMLDB functionality in the database, the database also can be used in a File server kind of way by enabling the XDB Repository HTTP/FTP or WebDav functionality via DBMS_XDB. XDB Repository Events are a kind of “triggers” that enable you to automatically trigger/do something based on the events triggered in this file/folder environment. For example, it is possible to automatically create duplicate files in the XDB Repository or secure them. Other possibilities are to read the content of such a file and insert that content, on the fly during the copy/paste action, into a relational table.
Most APEX enthousiast know of the PL/SQL Gateway, which is a small part of the functionality that is called the XDB Protocol Listener. Besides PL/SQL support, it also enables you to secure your data, as mentioned, trigger actions based, for example on MIME type, mount your database as a Logical Volume (currently only via WebDAV, eg. DAVFS) of your operating system. The XDB Protocol Listener can support your own solutions based on PL/SQL (like REST WebServices), but also C or Java based methods, and, out-of-the-box, Native Database Web Services (SOAP support) or direct XML content access via other “servlets” like the “ORADB/DBUriServlet” servlet method.
OOW 2011 – Oracle XMLDB and Big Data
Oct 6th
Last day of Oracle Open World and I am currently attending the last presentations. The first presentation, “Oracle XMLDB: A noSQL Approach to Managing all your Unstructured Data”, deals with the no-SQL approach and using Oracle XML DB in the context of using it with “Big Data”, that is unstructured data. The title of the presentation is “a bit” misleading due it reference to noSQL data handling. XML is mostly used in the area’s of structured, data centric, semi-structured an unstructured, that is document centric data. Due to the flexibility of XML, it can be used for bridging those data content forms. Via the XDB repository, xmltype storage and xmlindex, that content can be moved into the XML DB part of the Oracle database, mapped and categorized. You can use repository events to shred and filter this map while the data is going in regarding interfacing via FTP or WebDAV. In all the presentation addressed a lot of already known fact of the XMLDB functionality and not really how to use it with huge amounts of unstructured data.
Oracle XMLDB XQuery Update in Database Release 11.2.0.3.0
Sep 22nd
I just made use of the very cool OTN Virtual Developer Day Database site. In this environment you can follow OTN Developer Day sessions, for example, at home, while making use of all the material available on that site plus the downloadable Virtualbox OTN Developer Day Appliance. Despite you can choose for tracks like Java, .Net, APEX, there is also a database section which handles (as you might expect it from me regarding interest) Oracle XMLDB functionality.
There is a 1 hour webcast available from Mark Drake, Oracle Product Manager, that takes you along all the basics / general overview (basic due too it is too extensive to show it in only an hour) of possibilities of Oracle XMLDB functionality. For convenience there is also a PDF document that has most of the slide info of the webcast. It doesn’t contain the demo’s or extra Virtualbox OTN Developer Day Appliance first steps info, of course, and what to do to reset the training XMLDB environment in this appliance.
This PDF and the webcast starts with the Oracle safeguard (legal disclaimer), with the general product outline slide saying among others that Oracle is not responsible or obliged to actually build-in features mentioned in that release or in that form…etc…so in that context it looks like…
