Comment by rjand541: OKAY!! For the extreme newbie out there like myself. I may have an answer for you.
First: My setup is Ubuntu 9.04 in 64 bit mode, with Eclipse 3.4, GWT 1.6, GAE 1.2, Java 1.6 with the OOPHM plug in for firefox 3.0.11 I went through everything on these boards and bits and pieces were hidden here and there. My first real issue was this error... Exception in thread "main" java.lang.UnsatisfiedLinkError?: /home/bin/packages/eclipse3.4/plugins/com.google.gwt.eclipse.sdkbundle.linux_1.6.4.v200904062334/gwt-linux-1.6.4/libswt-pi-gtk-3235.so: /home/bin/packages/eclipse3.4/plugins/com.google.gwt.eclipse.sdkbundle.linux_1.6.4.v200904062334/gwt-linux-1.6.4/libswt-pi-gtk-3235.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) taha had a similar problem on this page: https://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/25d7c210c6b92e59?pli=1 The solution to which was to simply install a 32 bit version of Java, (Java 1.50) and have eclipse point to it under Properties -> Run/Debug Settings -> (select your project) -> edit -> JRE tab. The next error wasn't mission critical, but nonetheless, it annoyed the heck out of me... Gtk-Message: Failed to load module "canberra-gtk-module": /usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so: wrong ELF class: ELFCLASS64 This was solved by following the same steps above but instead of the properties tab hitting the environment tab. Then entering a variable called GTK_PATH and setting the value to /usr/lib32/gtk-2.0 That took care of that. Next up was this error... com.google.apphosting.utils.jetty.JettyLogger? warn WARNING: failed greetServlet java.lang.UnsupportedClassVersionError?: Bad version number in .class file This was solved by our 64 bit cousins on the Mac under this thread http://groups.google.com/group/google-appengine-java/browse_thread/thread/da29f92b3677a1ef Go to properties again, but this time select Java Compiler. Set the compiler compliance level to 1.5. That is it. It should fix your issues if you are in a similar boat as me. Try it out and everything should pop up fine and appear to be working. Or is it... I guess only time will tell. Thanks to the many that contribute to these boards.
