newbie question about java environment variables
Hi, absolute newbie to Java here.
I am trying to run a java app called KEA on XP. (fyi, it is KEA 3.0 and the URL is http://www.nzdl.org/Kea/download.html)
OK, I have unpacked it and I don't know where to start.
I do have the JRE installed at C:\Program Files\Java\jre1.5.0_11, and I know java works because I can type java at the command line and get a listing of the switches.
The readme for KEA says
"
To run KEA you need to tell the Java Virtual Machine where to look for KEA classes. One possible way of
doing this is to add the directory that contains this README file to
the CLASSPATH environment variable that is used by the Java Virtual
Machine.
Under Linux you would do the following:
a) Set KEAHOME to be the directory which contains this README.
b) Add $KEAHOME to your CLASSPATH environment variable.
"
Now, I don't appear in my DOS environment settings to have anything called CLASSPATH, and I don't know how to "set KEAHOME".
Can you please help me with these very basic steps, and then the next one. What do I type in to make KEA run?
java KEA ?

in windows,
1. right click "My Compute" icon in desktop.
2. Click Properties.
3. Click "Advanced" tab.
4. Click "environment Variables" button.
5. There add "KEAHOME" or class path as you want.

I am still stuck. Here is the output of the dos session.
You will note that I have the current directory on c: set to the java bin, and the current directory on f: set to the kea directory where the class is, but I get

Exception in thread "main" java.lang.NoClassDefFoundE
F:\KEA3~1.0\KEA-3.0>c:java

thankyou, people. It was I think a classpath problem, and maybe also because I had some spaces in the path. Anyway, it is going now, so .. thanks for the help.
