I have strange situation with class loading in Jboss 5.1. I have a restful service (use jboss resteasy) packaged in a war file. This service has a dependecy on jaxws-rt.jar which is packaged inside this war file. Also, we used jboss-classloading.xml to isolate class loading with following configuration:

<classloading xmlns="urn:jboss:classloading:1.0"

    name="myService.war"

    domain="myServiceDomain"

    top-level-classloader="true"

    parent-first="false"

    import-all="true">

</classloading>

Sometimes, the service cannot find classes inside jaxws-rt after stop server (remove tmp and work dirs) and start server. The frustrating thing is I can not reproduce it easily. I have read many postings regarding class loading and tried a lot of suggestions. I'm still not able to fix the issue.

Any suggestions are really appreciated.
