FC3 installed Limewire crashes with wrong Java version
 

I downloaded and installed Limewire in Fedora Core 3, I have the latest version of Sun's Java installed. After installing the RPM for Limewire and when I try to execute the program the following error is received;


UIDefaults.getUIError: failed to locate UI class:TextAreaUI

Something went wrong with LimeWire.
Maybe you're using the wrong version of Java?
(LimeWire is tested against and works best with with Sun's JRE, Java 1.4+)

Does Java work with any other programs?

Re: Java limewire
 

Yes, it works perfectly with Firefox and all other programs that use Java.

Do you have any tips on how to make it point to the correct place or how to make it work?

Nope, Sorry. I use Xnap, a java based open nap client, and don't have a problem, but don't have a clue what knd of specific issues Limewire may have.

Re: program
 

Which program do you use, do you have a link for it and is it free?

The symbolic link /usr/bin/java is poiting to the wrong java executable.
Locate the right java executable (for example /usr/java/jre1.5.0_01/bin/java).
Delete the symbolic link and make a new symbolic link to the right java executable.
In my case it was:

ln -s /usr/java/jre1.5.0_01/bin/java /usr/bin/java

After that everything worked.

fix for limewire (java)
 

thanks vanstra for the advice. it worked for me as well. my sym links pointed to /etc/alternatives. not sure why they were there.

Symlink Pointer
 

What is the command to delete the symlink, and how do I find where it is pointed
to?

re: symbolic link pointer
 

I found the symbolic link in /usr/bin. It looked like this java -> /etc/alternatives/java. There were also symbolic links for jar and javac. I did a change directory to /usr/bin (cd /usr/bin) and then used the remove command to remove the link just as if it were a file (rm java). I also used "rm jar" and "rm javac" to remove those links as well. Upon inspection I found that, in my case, the java, jar, and javac links in /etc/alternatives were pointed to shell scripts (ex. /usr/share/java/libgcj-java-placeholder.sh). Something to do with "jpackage.org JVM packages".

At any rate, once I had removed the symbolic links in /usr/bin, I followed vanstra's advice to create new links pointing to my currently installed version of Java. In my case the command was this: ln -s /usr/java/jre1.5.0_02/bin/java /usr/bin/java

That seemed to do the trick. Now when I load my java apps (such as limewire) it is able to correctly find and load Java via the new symbolic link.

Hope this helps.

Nice to hear that it worked.
