[2.0b1+drools 4.0m3]two ClassCastExceptions from the seam.dr

ellenzhao Jul 10, 2007 11:06 AM

I just updated the whole drools thing (core + dependencies) for my Seam application, and ran "ant dist" for Seam minutes ago and updated the seam libraries in my application. Now there is this problem(Warning: the stack trace is long. Sorry for that....)

Exception during request processing:
Caused by javax.el.ELException with message: "javax.ejb.EJBTransactionRolledbackException: org.drools.compiler.PackageBuilderErrors cannot be cast to java.util.List"

I saw there is this code in the org.jboss.seam.drools.RuleBase:

if ( builder.hasErrors() )
 {
 log.error("errors parsing rules in: " + ruleFile);
 for ( ParserError error: (List<ParserError>) builder.getErrors() )
 {
 log.error( error.getMessage() + " (" + ruleFile + ':' + error.getRow() + ')' );
 }

Why is this causing problem?

And a more interesting error in the working memory is:

- Component (recipeTagWorkingMemory)
class class org.jboss.seam.drools.ManagedWorkingMemory
ruleBase org.jboss.seam.core.Expressions$1@12e5050
ruleBaseName
statefulSession java.lang.ClassCastException[org.jboss.seam.drools.RuleBase cannot be cast to org.drools.RuleBase]
toString() org.jboss.seam.drools.ManagedWorkingMemory@18dd769

Any direction about how to fix it? I'm using Drools 4.0 M3 snapshot of today. Thanks a lot in advance!

Regards,
Ellen

These two problems are solved. The modification I made in the seam code base can be found here:
