[EJB/JBoss] - Issues with scoped classloader
by tnine
Hi All,
I'm receiving strange ClassCastExceptions due to class loader issues in JBoss 4.0.2, I try to turn off parent delegation. According to the post here
http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration
"Use the following constructs to enabled scoped class loading with the deployment classes overriding the server classes."
I have the following jboss-app.xml
| <jboss-app>
| <loader-repository>
| statements.purdueefcu.com:loader=statments-1.0.0-SNAPSHOT
| <loader-repository-config>
| java2ParentDelegation=false
| </loader-repository-config>
| </loader-repository>
| </jboss-app>
|
However, I still receive these errors. Whenever I run our POJO code in our integration tests, everything works perfectly. Once I package it up into an ear and deploy in JBoss, I start to see these issues. Specifically it seems to be a hibernate issue with annotations. I'm including the annotations version 3.3.0 ga, and hibernate version 3.2.4.sp1. It seems that either I'm missing a library in the include, or JBoss is not loading my classes first. Is my jboss-app.xml correct?

[JBoss Seam] - Target Unreachable error w/ Seam 2.0.0.Beta1?
by cupdike
Using Seam 2.0.0.Beta1 on JBoss AS 4.2, I generated my app using seam-gen. The list page for one of my entities, PpPemsItemMv, loads just fine and shows the table contents. However, when I try to filter using a search parameter, it blows up with the error below regarding "Target Unreachable".
Googling this via "seam target unreachable" finds several folks that had this error, but no obvious solution. Several folks suggested it was a configuration problem, but I'm using seam-gen which otherwise produces solid working examples (so I'm not sure what would be misconfigured).
Help appreciated. Thanks, Clark
