Re: [drools-user] Problem with serializing WorkingMemory

Thank you so much!  I checked out the trunk via SVN, and it did build for me.  However, when I moved the runtime jars (including the dependencies outlined in the README files) into my project,
I started seeing this error when I try to load up some DRL rules:

java.lang.NoSuchFieldError: recognizer
    at org.drools.lang.DRLLexer$DFA18.<init>(Unknown Source)
    at org.drools.lang.DRLLexer.<init>(Unknown Source)

    at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source)

I copied the antlr2 jar from the SVN checkout, but I don't see an antlr 3 jar, so I'm using the version from the 3.0.3 binary distribution.  Any idea what I'm doing wrong?
