[rules-users] Drools inside Netbeans module

Hello all, I'm using Drools 4.0.0.12865MR3 , Netbeans Platform 5.5 and JDK 1.6. When trying to instantiate a org.drools.compiler.PackageBuilder inside a Netbeans module I get the following exception: org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialect:java' at org.drools.compiler.PackageBuilderConfiguration.buildDialectRegistry(PackageBuilderConfiguration.java:156) at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:131) at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:84) Maybe this seems to be a ClassLoader issue. Regards, Andreas Boehm
