NullPointerException when starting ANY Webstart-Application

[M Schneider]

Whenever I try to launch any JNLP-file in my browser, I get the following error:

java.lang.NullPointerException

any help is highly appreciated.

From the stack trace, you are using Firefox and the deployer is falling down when trying to process your proxy server settings. So have a look at them and see if there's anything peculiar. (Tools, Options, Advanced, Network, Settings.)

Thanks, but I'm not using a proxy at all and the error is the same when I'm using IE.
