Automatic Updation of Client side Jars & other resources

Hi,

On Client side I have a thick client (Jide) and a scripting interface. It has multiple jars and many resources like property files,config files, python files,perl scripts and icons.
Every time Some jars are updated or some other resources are updated user has to install the latest setup.
What i want is that these jars & resources get updated automatically every time user launch the application.

I tried web start but found it difficult because a) found difficulty using JPF plugin framework with web start. b) I have scripting interface too for the users, which i don't think possible with web start

Is there any other possible solution?

Anybody has any info on this?

thanks

i'm also interested in knowing how to push updates to client side.

i got the info that in JNLP file href jar tag we can mention version number attribute ,and webstart pulls only those jars whose version number is
changed.[it does this by comparing timestamp of jnlp file and than checking the version number]

But the problem I'm facing is versioning the jar on server side . How to assign version number to jar files .
when we use jar command , it puts in version number in manifest.mf file , IS it jar version number
[every time we do jar it just puts in version 1.0 , how to change this ]
