bash: java: command not found

HI, I have a problem in that I am very familiar with Dr Java under the Windows OS and would like to use it on my Debian Sarge system. I have a project due basically in 2 days and I need to get started on it ASAP. I tried using Eclipse but its way too large for this project - maybe for the next project when I have more time it will be good to use but not yet. In order to run Dr Java I need to enter the command:

java -jar drjava-stable-20040326.jar

Now, this returns the reply from the Terminal:
bash: java: command not found

Now I know that indicates that java is not installed. However, I have installed it using the Graphical interface in the installer found on http://java.sun.com/j2se/1.4.2/download.html.

Now I need to get it so my program works perfectly on Java 1.4.2, so I need this version. What have I done wrong? After I ran the Java GUI installer I did nothing else as part of the install. Is there something more I need to do?

Thanks,
Peter

It's a PATH problem. You have two choices

Code:

specify the path yourself (I making up one here)

/opt/bin/lang/java ......

or change you PATH

export PATH="/opt/bin/lang:$PATH"

java ..............

There appears to be nothing in the java folder near where you specified except in the /opt/j2sdk1.4.2_04/j2sdk1.4.2_04/_uninst directory.

So what I did was set export PATH="/opt/j2sdk1.4.2_04/j2sdk1.4.2_04/_uninst"
I also tried export PATH="/opt/j2sdk1.4.2_04/j2sdk1.4.2_04/" and export PATH="/opt/j2sdk1.4.2_04/"

No luck though : (.

Any time I try java -anything- it gives the java command not found error

Or am I missing anything? I'm still a Linux Newbie : (.

Recovered old Java installation, apparently it didn't install correctly the second time I did it.

Checking docs now.

Fixed the hard and dirty way via copying the .jar file into my java/bin directory and making a launcher with the command: /opt/j2sdk1.4.2_04/bin/java -jar /opt/j2sdk1.4.2_04/bin/drjava-beta-20040908.jar

Thanks,
Peter
