Hi!
I'm working on a project that is using EclipseLink 2.1.1 for OR- and OX-mapping. When I try to deploy on JBoss 4.2.3.GA I get the following error:
{code}java.lang.LinkageError: loader constraint violation: loader (instance of org/jboss/web/tomcat/service/WebCtxLoader$ENCLoader) previously initiated loading for a different type with name "javax/persistence/LockModeType"{code}
Turns out the EclipseLink jar, which is included in the project war file, has an enum javax.persistence.LockModeType, and another enum with the same name can be found in ejb3-persistence.jar in the JBoss' server lib. This is the jboss-web.xml:
{code:xml}<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss-web PUBLIC "-//JBoss//DTD Web Application 4.2//EN" "http://www.jboss.org/j2ee/dtd/jboss-web_4_2.dtd">
<jboss-web>
<context-root>my-project</context-root>
<class-loading java2ClassLoadingCompliance="false">
<loader-repository>
my-project:archive=my-project
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
</loader-repository>
</class-loading>
</jboss-web>{code}
But it doesn't seem to do much good. Please help!
