Re: Download jars instead of keeping in CVS?

Nicola,

I suggest that you look again.  Java WebStart is an application launcher,
but look at the JNLP underneath it.  It is a resource downloading system.
As they say, and you quoted:

"The software distribution technology is only one aspect of JavaTM Web
Start.  It also provides security, updates to the applications,
ease-of-use for end users, and flexibility for developers when they
create the applications."

It's for "applications". Read on...

It cannot be used as-is though. It has no way of defining a jar
repository, and it gets resources like this:

 <resources>
   <j2se version="1.3"/>
   <jar href="lib/SwingSet2.jar"/>
 </resources>

The version is for the application.  For what you want to do, if each jar
had resource information in it, the check would be iterative.  For example
jar that you load, you check the j2se version necessary.

I don't get this (I read the other mail too)...

As you see there is no version info, the version info is about the whole
JNPL descriptor.

A better example, from my perspective, is:

     <resources>
       <j2se version="1.2+"/>
       <jar href="application.jar" version="1.1"/>
       <jar href="lib.jar" version="2.1"/>
  </resources>

Because that specifies which version of the jar is necessary.  See also
version.xml.

Is this in the JNPL spec? Didn't know.

There was a bit of misunderstanding here because IIUC you were talking
about getting the releases, I was talking about getting the jars for the
developers.

Why not use it for both?

I fail to see practical need for it.
Let me explain.

I want to get application.jar version 1.1 from http://mysite.net/
In practice, what do I need JNPL for? Where are the jars placed?

In JNPL I see that it specifies what jars are needed for an app, not how to make a repository of jars.

I see the need if I say: I want the jars for latest James.
Ok, then I check for the JNPL file of James and it knows what to get... but then, if I want the jars for James 1.1? Is there a scheme for asking for a specific version of the app?
