RE: [equinox-dev] Could not find main-class org.eclipse.core.laun cher.W

[Andrew Niefer <aniefer@xxxxxxxxxx>]

A NullPointerException at this location
implies that the org.eclipse.osgi bundle was not found.
It was looked for in the in the results
returned from 
Enumeration resources = WebStartMain.class.getClassLoader().getResources(JarFile.MANIFEST_NAME);

My bad Alex... Apparently
I can't read.  The following did work afterall.
 
  <application-desc main-class="org.eclipse.equinox.launcher.WebStartMain">
    <argument>-nosplash</argument>
  </application-desc>
 
Now we're getting a null pointer exception.
 But at least we've gotten past that part.  Here's the NPE that
we're getting if anyone has a suggestion on that.

Not sure if this helps, but
I did some more searching and it appears that we're having the same problems
that Tejah had back in August.  
http://www.eclipsepowered.org/forums/thread.jspa?messageID=92168477&#92168477
 
The link suggests that culprit
may be that the org.eclipse.equinox.launcher_1.0.1.R33x_v20070828.jar could
be referenced from the wrong jnlp.  I verified our jnlp and it looks
right to me.  So there's something else funky going on.
 
Anybody have any more ideas?

If only It was that easy.  =)
 I made the change as you suggested, but got the same error:  "Could
not find main-class org.eclipse.core.launcher.WebStartMain in http://localhost:18080/AgileCourtWebStart/org.eclipse.equinox.launcher_1.0.1.R33x_v20070828.jar"

In 3.3 the Webstart main class is org.eclipse.equinox.launcher.WebStartMain.

We left a stub org.eclipse.core.launcher.Main, but it looks like we forgot
to put a stub for the old WebStartMain.

I expect you simply need to change

  <application-desc main-class="org.eclipse.equinox.launcher.WebStartMain.class">
    <argument>-nosplash</argument>
  </application-desc>

We are trying to migrate our RCP application from Eclipse 3.2 to 3.3.1.1.
When we deploy the application, we get the following error:  ####
Could not find main-class org.eclipse.core.launcher.WebStartMain.class
in http://localhost:18080/AgileCourtWebStart/org.eclipse.equinox.launcher_1.0.1.R33x_v20070828.jar
  
Below is the full exception with the JNLP file included.  Does anyone
have any suggestions? 
  
Thanks,
