Affects Testing: Added: [Regression] Attachment: Added: drools_intg_jbqa1185.zip Tom Cunningham suggest looking in JNDIView to as the QS is doing a JNDI lookup and then casting the result to AuthenticatorRemote - figuring out what is actually at that JNDI address would be helpful See attached - it looks like the same class [ldimaggi@ldimaggi Desktop]$ cat CR3 CR4 | grep AuthenticatorRemote | | +- remote (proxy: $Proxy91 implements interface org.domain.DroolsIntCL_JBQA1185.session.AuthenticatorRemote,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject) | | +- remote (proxy: $Proxy91 implements interface org.domain.DroolsIntCL_JBQA1185.session.AuthenticatorRemote,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject) ------------------------------------- Also seeing this (in output from JNDIView) [ldimaggi@ldimaggi Desktop]$ cat CR3 CR4 | grep 101 | | +- local (proxy: $Proxy101 implements No ClassLoaders found for: org.jboss.seam.core.LocalDispatcher (no security manager: RMI class loader disabled)) | | +- local (proxy: $Proxy101 implements interface org.jboss.seam.core.LocalDispatcher,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject) Attachment: Added: CR3 Attachment: Added: CR4 There is definitely a difference between the two deployments as it is picking up different versions of the classes in each.
CR4 is loading the JNDI class from the EAR whereas CR3 is loading it from the ESB.

Prior to this change all JNDI accesses were forced over the network, as a remote client. After this change they would refer to classes within the local JVM. The error is really in the test in that it has two different instances of the remote interface, rather than sharing the same interface. It is for this reason that there are two classloaders being used. The test should be rewritten to refer to the same interface, a workaround in the meantime would be to force the PROVIDER_URL to jnp://127.0.0.1:1099. Testcase fixed (set provider url). |
Date of First Response: 2009-09-17 22:06:25 project_key: SOA Attaching a QS that works fine with CR3 and fails with CR4. There's a Seam app (packaged as an ear) with drools libs (Drools 3).
