Hi, I downloaded JRE1.4.2 and installed it on my Linux Ubuntu.
But it doesn't give me any feedback whether the installation was
successful or not. Just showed me the command line after executing the
install file.
Is there a way to know if JRE is successfully installed or not? Thanks!

Guyen,

You can use the command "which java" to tell you which version of java
shows up on your path first. If that returns something, that means java
is available. Next try "java --version" to determine if the one you
expect (1.4.2) is the one that's being run.

Hope this helps,
- Jeff
