[rules-users] Pojo with spring dependency in DWB

[Joe White]

For reference the uber jar approach also didn't work for this one. I created a jar with dependencies and added that and it still doesn't find the entity manager class. When adding spring-orm to the DWB manually (where the EntityManager lives)  I get the error below:

I'll keep after it to see if I can find an approach that works.

That's something I'm working on right now.

Some where in the dependency chain for @Component is EntityManager that is not included in your project's dependencies (I guess scope "provided" but it can occur for other reasons).

The best we're going to be able to achieve is handle the exception better in the workbench code. We can't do much about dependency chains.

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.
