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....

RuleAgent(testSolcredProfesion) INFO (Tue Aug 21 10:12:02 CLT 2007): Configuring with newInstance=true, secondsToRefresh=30

-------

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...  :)
