java problems!!
 

SOME java programs work however others give me the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: <some file>

any ideas or is it a problem with the specific program?

Is it LimeWire you are trying to install?
I got bunch of such errors when tried to install it. If not then try to download java1.3.1 from java.sun.com
or blackdown
make sure the new java is in your path.

Actually LimeWire was the one application i got working...

wow, lucky you, there are ppl (like myself) who can't figure it out.
Happy New Year!

Happy New Year!
 

That's a missing class file I think PuterFreaK. When you download java applets from th'internet some are already compiled, some are not.
Compile the application:

%javac <some file.java>

This will create a somefile.class file. Then:

%java <some file>

With no suffix.

and that should work. If not, I'd suggest that your CLASSPATH environment variables need to be set up - look at the installation instructions you dowloaded with the JDK (sorry SDK!). If you've used a number of classes which are executed in a main program then make sure all the superclass files are compiled (that is eg. the 'engine', 'doors' and 'wheels' programs for the main 'car' class).

That should do it.

p.s. forgetting to compile superclasses is something I'm very good at ;)

Here is what I did:

Remove Kaffe:
# rpm -e kaffe

Remove Jre:
# rpm -e jre

Reinstall Jre:
# rpm -Uiv jre<versionhere>.rpm

# ln -s /usr/java/jre1.3.1_01/bin/java /usr/bin

# export PATH="$PATH:/usr/java/jre1.3.1_02/bin"
I also added PATH="$PATH:/usr/java/jre1.3.1_02/bin" to the /etc/profile file so i wouldnt have to type that command every time I logged in.

After doing that LimeWire worked great (well....as well as to be expected..) but no other java programs work...


Bert, I dont have a command called javac....Any ideas?

Also, I wasnt trying to compile the application from the source...It got a binary.

Limewire works!!! thansk!! dhdhdhdhgdwbf

np

Oh, and i figured out why I didnt have the javac command...didnt have the SDK insalled...I installed that and now have that command but sitill cant get the program to work.

If anyone wants to try their luck at it grab it from http://prdownloads.sourceforge.net/j...011128.tar.gz..

Thanks!

Ok bad news. it doesnt work no more. I try to click on runLime.sh and nothin happans.

Btw i dont know how to add the PATH to the profile file.

I just have to keep adding the path to keep LIMEWIRE runnin'!!!

just add

PATH="$PATH:/usr/java/jre1.3.1_02/bin"

somewhere in the /etc/profile file (like at the top). Then if you are already logged in type

source /etc/profile

Thanks mate. FInally getting some things working in Linux hehe

One more question.

Can you make shortcuts ? or do i always have to cd into the application folder and execute commands?

Yep. One way to do it is add the following line to your .bashrc file (~/.bashrc):

alias limewire=/path/to/limewire/LimeWire

and then

source ~/.bashrc

I'm always having problems with a KDE window locking up when i double click on HOME.
