JNLP and Jar versions

[leliel]

Hi,
how do I version a jar file?
If I add version=0.1 to my JNLP file, the jws client write something about a nullpointerexception and the version field could not be found ?!
hope somebody could help.

hi Patrick
can you please post the jnlp file here?
what you exactly mean when you say you want to "version a jar file"?
i've never versioned it...so little more light on that would be a great help for further thinking...
regards
maulin.

Hi,
this is the jnlp file:

<?xml version="1.0" encoding="utf-8"?>

</jnlp>

there's an optional tag for <jar href> named version. I thought about adding the version, so webstart would only leech new files through the net.

You can set the version of your jar using the "version-number" attribute in the Manifest file included in the jar.
