<p dir="ltr">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).</p>

<p class="MsoNormal">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?<u></u><u></u></p>
