> 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
