BTW, when using Java, is there a way to save the .java files created by the compiler? I would like to understand the specific environment/scope in which consequences are compiled. Right now, if something goes wrong, the .java are deleted right away. I looked at PackageBuilderOptions, but didn't see anything there. - Godmar On 9/24/07, Mark Proctor <mproctor@codehaus.org> wrote:Java is more mature in tooling and implementation and is still currently the default implementation and the recommended one if you are not sure. MVEL will eventually become the default dialect when it matures, its advantage is in the simpler language it provides, which helps make rules easier to read and write. It can also operate in reflection mode, which can really help for large rule based systems that have perm gen issues. Mark ekke wrote:can someone tell me, when to use java or mvel as dialect ? I've experienced that in some cases inside the drl editor using java gives me more context-help then using mvel but: what can I do with java and not with mvel and what advantages has mvel compared with java which dialect is more performant ? thx for infos from insiders ekke_______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users_______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
