You need both 2.7.7 and 3.0b5 - we use StringTemplate and Antlr3, but
antlr2.7 is a dependency of StringTemplate :(

	Hi, 

	I refer to a JIRA issue 578, which was rejected, however I am
still having dramas with it: 

	When attempting to create a package from a class called by a JSP
( see below) I get the following error:
	
	CharScanner; panic: ClassNotFoundException:
org.antlr.stringtemplate.language.ChunkToken
	Stopping the Weblogic Workshop debugger...
	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.
