GWT fails to launch sample apps

[kickabear]

I've downloaded GWT (Google Web Toolkit) from Google, and untarred it. I tried to lauch the KitchenSink sample app, but get an error similar to the one below. I tried to create a new app, and I got the following error:

Exception in thread "main" java.lang.ExceptionInInitializerError
at java.lang.Class.initializeClass(libgcj.so.70)
at java.lang.Class.initializeClass(libgcj.so.70)
Caused by: java.lang.IllegalArgumentException: URI "file:./gwt-dev-linux.jar" is not hierarchical

at java.lang.Class.initializeClass(libgcj.so.70)

I've tried searching, but I can't find anything related to this one. Any help would be great. Thanks!

On 7.04 I found that it was because GCJ was installed.

sudo apt-get remove gcj libgcj-common libgcj7-0

and installing a sun jdk cleared it right up.

This works, but actually removing gcj removes eclipse by the way.

Viktor provides solution there:

sudo update-java-alternatives -s java-6-sun

This works with eclipse 3.2.2 & sun-java6-jdk

You may also need the GNU C++ Library (I did!)

aptitude install libstdc++5

:popcorn:

I'm running Intrepid, with OpenJDK 6 and Eclipse 3.4.1 (Ganymede) installed. I downloaded the GWT distribution for Linux and followed the instructions in the section Creating an Application from Scratch (with Eclipse) (http://code.google.com/webtoolkit/gettingstarted.html#NewEclipse).

When I clicked the 'Run' button, I was getting an UnsatisfiedLinkError: cannot resolve libstdc++.so.5

Based on the above suggestion, I just ran apt-get install libstdc++5 and that completely fixed the problem.

Thanks!

Yep, went through the same thing. Here's a guide on configuring GWT and ubuntu (http://whatwouldnickdo.com/wordpress/99/unable-to-load-mozilla-for-hosted-mode-gwt-ubuntu-810-linux/).
