Debugger Stopped. The Weblogic server stops as well. Here is the code snippet called by the jsp PackageBuilderConfiguration pkgBuilderCfg = new PackageBuilderConfiguration(); pkgBuilderCfg.setCompiler(PackageBuilderConfiguration.JANINO); PackageBuilder builder = new PackageBuilder(pkgBuilderCfg); builder.addPackageFromDrl((new InputStreamReader(new FileInputStream("c:\\myruleresource.drl")) ) ); The solution seemed to be: It seems it is a classpath issue with Weblogic.I added the antlr-2.7.7.jar to the pre classpath and the errror no longer manifests itself Well I have tried the above and it does not work. I am using weblogic 8.1. This is driving me round the twist any help is greatly appreciated. What version on antlr should I be using with drools3? Cheers, Matt.
