Java JNLP self signing jars

Question

When i create an unsigned JWS (Java web start) app, user will have to confirm any action that might harm his system. As i don't have money (nor need) for proper signing my JWS app, how can i (and, can i at all) create certificate for myself and self-sign my jars. I want to prevent Java from asking for confirmation on any single "out-of-sandbox" action, but to ask user only once during initial startup "do you want to give full rights to this app"? Is that possible with self-signing the app.

Note: all my users trust me and my app, and they would be ok with "do you want to give all rights to this app" question.

Answer 1

To make your Java Web start work you need signed JARS.

But you don't need money for that.

Install this Eclipse plugin

Eclipse Webstart Plugin.

You will just need to export as "Webstart". It will prompt you to sign the jars.
