Using ServiceManager

[Pawe� Morgan]

I use the following line to get ExtensionInstallerService.

ExtensionInstallerService service = (ExtensionInstallerService) ServiceManager.lookup("javax.jnlp.ExtensionInstallerService");

After installation is successfull I simply wont to extract jar in user directory. My application has allPermission.

When I call ServiceManager for each service it gives me "UnavailableServiceException".

What am I missing???
Please help,
