I am new to both JBoss and EJB2.0 and the new CMP support. Using XDoclet I can create a couple of beans that include simple CMP and CMR fields, generate and deploy an ear to JBoss, and it appears to install it with no WARNings.
But using a simple client I find that the value of my CMR/foreign key field never changes from null. This is irrespective of whether I set it in the ejbPostCreate or call it after create() returns to my client. I'm assuming it's either a problem with my example or my JBoss configuration. But I would dearly love to know where the problem is. Cheers for any help David Jones Example showing problem: ------------------------ I have created a minimal example that is reworked from the Version2.zip of Tim Chartrands "CMP 2.0 With JBoss 3.0 Beta Tutorial". http://iris.cs.byu.edu/tim/462/tutorial/tutorial.html Company long id ->CMP & primary key String name ->CMP Employee long id ->CMP & primary key String email ->CMP CompanyLocal company ->CMR field linked to Company 1:M I have made the example available on my website: 47kb This includes the source, build.xml and a built ear ready to deploy. http://www.night.dircon.co.uk/jboss/cmr-example.zip To try it out: - Unzip downloaded cmr-example.zip under temp - Copy dist/cmr-example.ear to jboss-3.0.0_tomcat-4.0.3/server/default/deploy - Modify build.xml to point to the installed location of jboss - ant client You should see a dialog of the client creating a company, followed by an employee. Showing that the employees company CMR field has not been persisted even though it was set in the employees ejbPostCreate. Then the client will explicitly set the employees company, and for me at least when asked afterwards the employee still says that its company is null. This dialog is included at the end of the email. Software I'm using: ------------------- jboss-3.0.0_tomcat-4.0.3 - using unmodified default jboss configuration with hypersonic db sun jdk 1.4.0-b92 xdoclet 1.1.2 ant 1.4 Win2k fixpack2 Traces from running client: --------------------------- Client console output on executing: ant client [java] -------------------------------------------------- [java] The aim of this client is to show the CMR field that [java] associates the employee with its company is not being [java] persisted away during either create or after.
