Automatically clearing the Java Web Start Cache

Question

I have a Java Web Start application. I specify the resource (jars, images, etc) version and change every time there is a new version. Unfortunately sometimes the resources are not always updated when there is a new version.

Is there any automated (possibly include in the application) way of clearing the web start cache?

Answer 1

Not in a reliable way.

We have found that making the URL unique for each item helps a lot. In other words deploy to "foo/20100310/main.jar" etc and update the JNLP file accordingly.
