Invoke action with doubleclick on Jtree node

I have a JTree with nodes and an action I would like to invoke by double clicking on one of the nodes.

I`ve implemented a MouseListener to check if the user makes a double click on the node.

Now I have the problem that the actionPerformed method which I want to invoke needs an "AnActionEvent". Is there a way to manually create one? Or how can I generally invoke the "actionPerformed" method with another method?
