Try setting your JAVA_HOME variable first. For example:
Code:
$ export JAVA_HOME=/path/to/jdk
$ javaws http://www.sunspotworld.com/SPOTManager/SPOTManager.jnlp
If that doesn't work, try linking Lenny's install location to the standard Java location (they're generally different):
Code:
# mkdir -p /usr/java/
# ln -s /path/to/jdk/ /usr/java/latest
If that's still not working, make sure you've really got the JDK installed and in your PATH:
If you get "command not found", then you might need to play with your PATH and verify you really installed (Sun's) JDK.
If you still aren't having luck, post the output of the following commands:
Code:
$ java -version
$ whereis java
Good luck!
