Error starting file in Java Web Start

I am trying to launch a java application via web launch and I am getting the following error which I cannot understand. Any hints, tips or tricks to solve this problem will be greatly appreciated.

When Web Launch runs the installer-desc class, you need to know the installation result. If he does not receive a response, an exception will appear.

Communicate with Web Start as follows:

 ExtensionInstallerService installerService = (ExtensionInstallerService) ServiceManager. lookup("javax.jnlp.ExtensionInstallerService"); //Say Successfully installerService.installSucceeded(false); //Say failure installerService.installFailed();

I noticed that you have

 <homepage href="null"/>

This seems to be the source of your problem? If you do not have a homepage, you can try to exclude this tag instead of setting a value of zero.
