RE: [rules-users] eclipse-jdtcore.jar

I eventually switched to JANINO because we are not using any Java 5 features. I discovered that some of the info available on the web is outdated when switching between Eclipse JDT ad Janino. The following system property has to be set: drools.dialect.java.compiler=JANINO some docs/posts referred to drools.compiler=JANINO I was hoping someone could indicate if/how properties can be configured when using JSR-94 to influence the compiler choice or other properties drools looks for. _____ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Mark Proctor Sent: 03 June 2008 17:19 To: Rules Users List Subject: Re: [rules-users] eclipse-jdtcore.jar Corneil du Plessis wrote: Problem I have is that it is in WebSphere/lib so it gets loaded before anything in my application, when the classloader is set to parent first. When I change the class loader to parent last I run into a new set of problem with some of the XML based libraries. If you search the mailing list archive, I believe people have resolved that issue. You can always switch drools to use janino too, see the wiki for more details on that. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Marcus Ilgner Sent: 03 June 2008 15:35 To: Rules Users List Subject: Re: [rules-users] eclipse-jdtcore.jar Hi, just as a side note: I had one project using Eclipse which already used another version of the JDT core. Encountering the same problem, I just put the core-3.2.3.v_686_R32x.jar from Drools in my project, too, and it worked without problems.

It's not a bug in drools, but is related to the dependencies of the drools-compiler. There's a big chance that you have a different version of the JDT core jar in your classpath (drools depends on version 3.2.3 - the filename of that jar is core-3.2.3.v_686_R32x.jar). This jar is used by drools to compile the rules. I hope this helps you to solve this issue.
