Oh, and after doing the above, drools is now not working when I startup the app for real - so obviously I've done something wrong. Here's what I see: Caused by: java.lang.NoSuchMethodError: org.drools.compiler.PackageBuilderConfiguration.setCompiler(I)V | at org.jboss.seam.drools.RuleBase.compileRuleBase(RuleBase.java:41) | ... 85 more Anyone know what I'm doing wrong? And is seam-gen working correctly or is it just me? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4068573#...
