          Hi Abhiram,

          Let's say that nobody have a specific example about Liferay, Vaadin and jBPM, so in order for us to help you, you will need to be more concrete, about what kind of issues are you facing. Did you add the jBPM dependencies to your project? Did you tried to run a process? What are the errors? Those kind of things will help us to help you

           

          Regards
