Richard Ambridge commented on JBRULES-2348:
-------------------------------------------

If i change this from:
   for ( TypeDeclaration type : newPkg.getTypeDeclarations().values() ) {
                    lastType = type;
                    type.setTypeClass( this.rootClassLoader.loadClass( pkg.getName() + "." + type.getTypeName() ) );
                }
            }
        } catch ( ClassNotFoundException e ) {
            throw new RuntimeDroolsException( "unable to resolve Type Declaration class '" + lastType.getTypeName() + "'" );
        } 

to:  (using getTypeClassName  and remove the pkg.getName())

 for ( TypeDeclaration type : newPkg.getTypeDeclarations().values() ) {
                    lastType = type;
                    type.setTypeClass( this.rootClassLoader.loadClass( type.getTypeClassName() ) );
                }
            }
        } catch ( ClassNotFoundException e ) {
            throw new RuntimeDroolsException( "unable to resolve Type Declaration class '" + lastType.getTypeClassName() + "'" );
        }

it works.
