Re: Re: Strange ClassCastException when looking up SLSB RemoteHome from "external" .war webapp

I created an issue for this:
http://jira.ow2.org/browse/JONAS-315

Fortunately, I may have a fix for this.
I has been committed just some minutes ago, it will be in the next 5.2 
nightly build:
http://maven.ow2.org/maven2-snapshot/org/ow2/jonas/assemblies/profiles/jonas-full/5.2.0-M4-SNAPSHOT/

Tell me if that solves your issue.
If so, I'll close the bug and backport it into 5.1.

Thanks
