:bash java: command not found
 

Hi everyone, I've just installed java (jre-6u21-linux-i586.bin) on Red Hat 4.4 AS and issued this command to check the java version: java -version
and got :bash :java: command not found

So this tells you that the java executable is not in your current path.

Have a look at your install instructions and see if maybe an environment variable needs to be set (maybe JAVA_HOME)

Also, do a find and make sure that the executable does actually exist somewhere??

If you try:

It should confirm post #2 in that your JAVA_HOME environment variable does not exist AND that you haven't added the executable directory of your Java installation into your PATH.

Basically you need to add the following to your bash_profile:

Once in your PATH at an OS level you can run java -version.

Having JAVA_HOME setup is also very useful in that your application servers and/or IDE will look for this variable.

Thank you. Will try your suggestions and post feedback

The CentOS way : Something like this :
1) su
2)
3) /usr/sbin/alternatives --config java
(( 4) /usr/sbin/alternatives --config javac ))
