Subject: [rules-users] Pojo with spring dependency in DWB

What is the best way to import a jar that has a spring dependency into the Drools Workbench? When I upload my pojos that I intend use in my rules I get the exception below. Do I also need to load the spring jars for this to work or is it not possible?

Specifically I need my rules objects to have the @Component annotation so that they can be autowired.
