[jboss-user] [JBoss Seam] - Re: Problem injecting drools WorkingMemory

[sjmenden]

I am following the example as closely as I possibly can.  I can not track seam to track down this problem.

Here is the directory structure of the drools example deployed and my application deployed:

There are a few difference in location, like I have some libs in WEB-INF/lib whereas drools has it in <EAR dir>/lib

I don't think this matters though because I have the correct paths in my application.xml.  My application deploys fine, but the first time I try to access a page which accesses drools I get:


  | 17:16:25,918 ERROR [STDERR] StringTemplate: problem parsing group <unknown>: java.lang.ClassCastException: antlr.CommonToken cannot be cast to antlr.Token
  | 17:16:25,919 ERROR [STDERR] java.lang.ClassCastException: antlr.CommonToken cannot be cast to antlr.

Do you guys have any pointers whatsoever as to the means that I can debug this problem.  I will, as a last resort, take the drools example and copy all of my files to it and see if that works, but right now I am running a seam-gen project that has a little different dir structure.
