Configuring one class loader per ear?

[skipoles]

I need to deploy two enterprise applications (as ear files) to the same JBoss instance. The problem that I am having is that they both contain different versions of the same classes (e.g. 1.ear contains v1.1 of x.y.ZClass and 2.ear contains v1.3 of x.y.ZClass). By default it seems that once x.y.ZClass is loaded both applications share the same loaded class file, rather than their own versions.

Is is possible / how do I configure JBoss so that there are separate classloaders for each ear file?

According to the Wrox JBoss book, you need to enable scoped classloading in your .ear files by editing jboss-app.xml in the ear file META-INF directory.

<jboss-app>
<loader-repository>
petstore:service=LoaderRepository

</jboss-app>

Details are sketchy though - please let us know if it works, or if it causes other problems.

Yes it works. Thanks very much. The only syntas change was that the line should be :loader=.

The Wrox bok also goes on to say that this facility does not work on 302 and prior releases.

Does anyone know what relaese the bug is fixed in?
