How to publish a Java Web Start jnlp application without security warnings?

Question

I have a Java application that is launched from a jnlp file off of a website. I\'m trying to get it to run without flashing up a bunch of security warnings before it runs.

Answer 1

Yes , you have to update all jars
You can add these properties directly into manifest of the jar files (all jars) from a file -

In your plugins directory :

jar ufm <jar_file> additionalAttribute.txt

This additionalAttribute.txt will contain your additional manifest attribute like -

Permissions: all-permissions  
Codebase: *  
Application-Name: My App  
Caller-Allowable-Codebase: *  
Trusted-Library: true
Application-Library-Allowable-Codebase: *

Answer 2

Do I have to update the jar manifest for the third-party libraries that I'm using as well?

Yes. All parts, all Jars of our applications have the same security requirements.
