packages and rulebases are serialisable<br>

compilation is done when you call addPackageFromDrl(). getPackage just
does a bit of maintenance before returning it.<br>

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.

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.

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
