Web start fails to launch on Mac OS X 10.5.8

[Austin]

Hello Folks,

First attempts to launch via web start fail with the following stack trace. Yup, I'm running java 1.6. Looks like it's missing a widget from Eclipse. I'm a java developer with Eclipse installed. I wonder if that is the problem or more likely a required jar file didn't make it into the jnlp?

Any help would be appreciated. I'm psyched to help out with developing this project.

-cheers, Austin

Hi Austin,

is it possible that Eclipse SWT classes from your system installation interfere with those from the RouteConverterMac.jar? Probably different versions?

org.eclipse.swt.widgets.Display at least is part of the webstart/cocoa.macosx-3.5.jar....

From the JNLP file:

<resources os="MacOS" arch="x86">
<jar href="webstart/cocoa.macosx-3.5.jar"/>
<jar href="webstart/mac.os_x.x86-1.3.6.jar"/>
<jar href="webstart/jna-3.0.7-stripped.jar"/>
<jar href="webstart/mac.os_x.x86-3.0.7.jar"/>
</resources>

I'm a java developer with Eclipse installed. I wonder if that is the problem or more likely a required jar file didn't make it into the jnlp?

That is good news. Did you already check out the source?
