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

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.

 

java.lang.NullPointerException

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,
