RE: ClientContext.storeFile idiosyncrasies

Hi Cameron,

Yes, this Java Web Start security issue.

You need to:

1. Install AllPermissionsFileService in your custom JNLP launcher by
extending/copying DefaultJnlpLauncher:

   ClientEnvironmentAdapter.setFileService(new AllPermissionsFileService());

2. Sign ALL jar files that are part of the ULC client.

There is already a related issue: http://www.canoo.com/jira/browse/UBA-1065

I hope this helps.

Thanks and regards,

Janak
