Within the OSB 10.3 you use XQuery code to perform data transformations. These transformations can be very complex. I am in favor of TDD and i want to use automatic tests for XQueries. You can use the OSB Console to test XQueries but this is not very practical with complex Queries and takes a lot of time.You can also use XQuery and JDeveloper to run XQueries and this inspired me to write a simple XQUnit module to test xqueries. This blog shows you how to set up automatic tests with the use of JUnit , XMLUnit and Oracle XQuery engine. The contraints for me were: 1) The XQuery code should be as-is, so no changes with scripts or whatever. The XQueries are used within the test framework as used within the OSB. 2) The XQuery engine of the WLS must be used. I could use some other XQuery engine, but this would not test the real WLS engine and still errors could occur runtime. 3) The test framework can be used within Java unit tests. This way it can also be used within Maven for instanc

There were probably already hundreds of discussions about versioning XML schemas and WSDL documents. This Blog considers the strategy described in Thomas Erl's "Web Service Contract Design and Versioning for SOA". How would you use these practices within a CDM? This Blog considers some options you have when developing XML Schemas out of you logical CDM. Consider a small CDM in which the following model is used. LegalEntity <-- NaturalPerson <-- Employee                   <-- NonNaturalPerson Namespaces For these entities you have some possibilities to use namespaces: 1) A group of Entities share the same namespace Example: http://www.blog/organisation/v1 2) Each Entity gets its own namespace Example: http://www.blog/organisation/legalentity/v1 http://www.blog/organisation/naturalperson/v1 The advantages of option 1 are Only 1 namespace needed, namespaces are hell as we all know The entities belong together so this seems logical The disadva

Today I was struggling with WLS 10.3, Workshop 10.3, JPA and Hibernate to get an Entity persistent to a Database. I got the following error: I used the following code (which was acutally generated by Workshop!): @Entity() @Table(name="werknemers") public class Werknemer implements Serializable { //default serial version id, required for serializable classes. private static final long serialVersionUID = 1L; @Id private String persNummer; private String emailInternet; public Werknemer() { } @Basic() @Column(name="email_internet", nullable=false, length=128) public String getEmailInternet() { return this.emailInternet; } public void setEmailInternet(String emailInternet) { this.emailInternet = emailInternet; } } As you can see from the error code the column name "email_internet" (as indicated by @Column) was not taken, but instead the "emailInternet" property was taken. I could not find the problem, but the followin

On the 22th and 23th of october 2009 the second SOA Symposium and first Cloud symposium took place in Rotterdam. For me it was the first SOA Symposium. The main theme of this symposium was the introduction of the SOA Manifesto by some respectful people of the SOA community like Thomas Erl, Anne Thomas Manes and Grady Booch. There were 6 SOA tracks, 2 Cloud computing tracks and a working group that worked on Candidate SOA Design patterns and the SOA Manifesto. The first day I followed: The Convergence and Unification of SOA, EDA & BPM, by Manas Deb, Oracle This presentation was about to think about the business events that occur within your business and to take these events into account early. So it should be natural to combine events, services and processes to create the need for the business. Events were also used to split complex processes. At the end of the presentation his new book was given away and I got hold of one piece (see also here for a book review). Servic
