Launching a webstart application (jnlp)

[Eva]

I have to test some plugins added to an application for which I cannot access the source code.

The main application is launched via a jnlp file.

I read back the topics here, but the only one dealing with this type of problem proved inconclusive.

Is there a way to handle this with FEST?

Or should I try to "deconstruct" the jnlp operations manually? 

Maven is handling all the dependencies for the project.

Any suggestions from anyone?
