I switched from Suse 10 to FC5 and now when I try to launch JBidWatcher from the console

java -jar JBidWatcher-1.0.jar

I get the following error:

I am running the latest version of Java

What am I doing wrong?

Greetings,
Your default Java is the not-yet-functional GCJ version.

The GCJ version of Java is incomplete, and should not be used as the default. Despite this, Redhat and others have made it the default. :(

Anyway, if you haven’t installed Sun’s version of Java for Linux, do so at:
http://java.sun.com/getjava

If you have, or once you have, you need to make sure you’re running that, and not the ‘default’ Java, wherever it may be.

I’d generally suggest creating a small shell script which runs Java specifically from your Sun Java install, which should be something like:
/usr/java/jre1.5.0_09

In any case, I’d avoid the GCJ version of Java for now.

(You can tell it’s the GCJ version, because of the line:
at java.lang.Class.initializeClass (libgcj.so.7)
which references libgcj.)

I hope this helps!

Thank you so much!

I really love this program a lot and was sad it did’t want to work!

Here is my shell script for any one who maybe needs it later on:

In text editor

#!/bin/bash

1. JBidwatcher
   echo Launching JBidwatcher
   /usr/java/jre1.5.0_09/bin/java -jar JBidWatcher-1.0.jar

save the file (I called it JBidwatcher)

in your terminal window type
chmod 755 JBidwatcher (or what ever your file name is)

copy this file to your /home/bin directory (if you don’t have one make it)

Now all you have to do is type JBidwatcher in your terminal window and away you go!

>>I know this seems simple to all the brilliant minds that hang here but some of us need dumbed down directions :)

May you be blessed!

George,

for those who need dumbed down instructions ;-) you forgot to tell that

a) JBidWatcher-1.0.jar has to be in the same location as this script is
b) typing JBidWatcher in the terminal only works if
1) you are in the directory /home/bin
or
2) the path to /home/bin was added to the path environment in your shell

I don’t know anything about Fedora FC5 but I suppose a path like /home/bin should include the username somewhere if you want it to install for a single user. Otherwise a location like /usr/local/bin would be more appropriate. Your distribution probably encourages you to use a proper location for either user-based or system-wide usage, which they tell you about somewhere in the documentation.

P.S.: You might want to tell your vendor about the confusion these incomplete GNU Java Compiler stuff is spreading among the less geeky users.

SUN Java should be GPL’d soon so hopefully this will solve the GCJ problems…
