[rules-users] Antlr problem in websphere

[Nirmal.R]

I get the following error : 

CharScanner; 
panic:ClassNotFoundException:org.antlr.stringtemplate.language.ChunkToken
and then the server stops by itself.

I'm using community edition of websphere. Are you using the same??
Websphere CE contains only antlr2.7.5 in its repository. I read about the
dependencies in jboss wiki it says drools need antlr3.0.ea8 and string
template needs antlr 2.7.6 and i've copied the jars as per the doc.
