Webstart client fails to launch the application from the cache. After webstart client downloads the application files to the client, it fails to launch from command line when specifying the -offline flag.

When trying to run:

javaws -offline http://localhost:8080/ws/BCREDIT/testws/BrokerTec.jnlp

We first see a popup stating "the application has requested to go online. do you want to continue" with ok and cancel buttons.

If you click OK, you then get an "Application Error" stating that "Unable to launch the application". If you click on the Details button you see:

Exception

However, if you launch javaws -viewer, you are able to launch the cached application by clicking on the icon for that application.
