How do you debug the camunda engine?

Hi,

I am new to camunda. I have done some changes to add new form field types in the camunda-engine source code.

There is issue when parsing the bpmn file. The engine is not able to interpret the new filed types I have added. So I want to debug and check where it could be breaking.

Can you tell me how I can debug the engine source code?

You can debug the process engine like any other Java application. In case it runs on an application server, you can apply remote debugging. How to configure this depends on the server in use and should be covered by its documentation.
