Just to re-iterate commons-jci-core-1.0-406301.jar has this class CompilationResult (with different packaging) which does NOT have getProblems() method. But I have another jar core-3.2.0.666.jar in my application, which has org.eclipse.jdt.internal.compiler.CompilationResult class with getProblems() method as expected. so this class with the required method is definitely there in the classpath. is there any other jar that is missing? or anything else?

This is resolved now. For benefit of others, i added the system variable in websphere console drools.compiler=JANINO This at runtime uses janino compiler api instead of using eclipse compiler, which seems to have conflict with the websphere app server's internal eclipse API.

Thanks Steve, I tried PARENT_LAST option, but that did not help. I will consider upgrading to 6.1.0.3. in the meanwhile i have the solution to this, by using JANINO instead of ECLIPSE. cheers, Vishal Steven Williams-3 wrote: > > Hi Vishal, > > We had similar problems which we resolved by upgrading to WebSphere > 6.1.0.3. > This version uses the same 3.2 jars as jboss rules.
