No problem, the jars that are no longer needed are as follows: antlr-2.7.6.jar antlr-3.0ea8.jar commons-jci-core-1.0-406301.jar commons-jci-janino-2.4.3.jar commons-lang-2.1.jar commons-logging-api-1.0.4.jar drools-compiler-3.0.5.jar drools-core-3.0.5.jar janino-2.4.3.jar stringtemplate-2.3b6.jar Note that some of these have been replaced with later versions, as listed in my original post.
