Browser Widget Issue on Ubuntu Gusty Gibbon

[Lucas de Oliveira]

Hi there!
I'm struggling make the gwt browser to work on Ubuntu Gusty Gibbon but
everytime I try that I get the following error:

[ERROR] The browser widget class could not be instantiated
org.eclipse.swt.SWTError: No more handles
(java.lang.UnsatisfiedLinkError: /opt/devtools/libs/gwt-linux-1.3.3/

By the way: both libxpcom.so and libplds4.so are on /opt/devtools/libs/
gwt-linux-1.3.3/mozilla-1.7.12/ so it's probably not a "No such file
or directory" problem.

any ideas?

thanks in advance!

By you stating that they are there, I'm assuming that you mean they
exist, they aren't broken symlinks and that you have the correct
permissions to access said files.

Brute force. This is open source - attach a debugger with a breakpoint
in BrowserWidget and see what is happening.

Cheers,

James

Hi Lucas,

This is a well known problem with how some distributions configure the Eclipse libraries used by GWT.  Here, these previous group threads where other people discussed this problem might help you:

Hope that helps,
