Hi,
Im trying to test the RuleAgent to get a pkg from BRMS (url) but it
cant load the pkg (which was succesfuly
created) from the snapshot url given by BRMS. If I try to connect to
that URL I inmediatly get the pkg to download...
Tryed to debug but I stoped at
DroolsObjectInputStream oin = new DroolsObjectInputStream(in);
return (Package) oin.readObject();
at HttpClientImpl.java... the readObject() fails from ObjectInputStream.
Here is the stacktrace....

Also downloaded the pakage from the BRMS and used simple
BinaryRuleBaseLoader:
BinaryRuleBaseLoader loader = new BinaryRuleBaseLoader(ruleBase);
loader.addPackage( CONTEXT_CLASS_LOADER.getResourceAsStream
( binaryPackageFilePath ) );
but I have a problem with serialization... my first thought was about
different mvel jars, replaced mvel jar in my classpath with the one
in BRMS war, but
the problem is still there... Im using Enum clases (enum types from
1.5), maybe this is the problem?... because I cant set the
serialVersionID in enums.

Thanks for help... I really need to use enums in my model... :)
