----------------------------------------------------------------
Key: DROOLS-494
URL: http://jira.codehaus.org/browse/DROOLS-494
Project: drools-legacy
Issue Type: Wish
Components: all
Environment: JDK1.6
JBoss Application Server v4.2
Drools 4.7
javassist
Reporter: Shawn Ritchie
Attachments: rules2.drl, SampleApp.rar
The issues is this guys i am creating a bean dynamically in this simple example
i have an arraylist of strings which will create a private field, and a getXXX
and a setXXX method for each of these fields
The problem arises when i try to load the .drl file in the package builder
which gives me the follow error (SEE BELOW)
I suspect it has something to do with the class loader or the package structure
in the rules?
Any suggestion reading material or help would be greatly usefull
the code i have loaded is a simple application which replicates the error
