[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: How to use my own common-collections.jar in jBoss 4.2.x

[Mrityunjay]

We tried the following steps for implementing classpath isolation in jBoss 4.2 (but not working as expected).


First, edit the conf/jboss-service.xml file and set the NamingService CallByValue to true:


<!-- The call by value mode. true if all lookups are unmarshalled using
the caller's TCL, false if in VM lookups return the value by reference.
-->
true

...


Second, edit the deploy/ear-deployer.xml file and set the Isolated and CallByValue attributes to true:


<!-- EAR deployer, remove if you are not using ear deployments -->

<!-- A flag indicating if ear deployments should have their own scoped
class loader to isolate their classes from other deployments.
-->
true
<!-- A flag indicating if the ear components should have in VM call
optimization disabled.
-->
true



Last, edit the deploy/jboss-web.deployer/META-INF/jboss-service.xml file and set the Java2ClassLoadingCompliance and UseJBossWebLoader attributes to false:





<!-- Get the flag indicating if the normal Java2 parent first class
loading model should be used over the servlet 2.3 web container first
model.
-->
false

true

<!-- A flag indicating if the JBoss Loader should be used. This loader
uses a unified class loader as the class loader rather than the tomcat
specific class loader.
-->
false

----------------- The exception we are getting are as follows----------------
