Hello

I am new to Eclipse so the question may be domb.... Ok, I am trying to
install eclipse on a Linux machine (running redhat). And I finally got
the program to run. But, when I tried to test run a simple program
("HelloWorld"!!!), I got this "Launch Failed" message: "The active
editor does not contain a main type." The main method exists, but it
seems the editor does not reconize it. Does anyone has idea what's
going on here?
Thanks for any help.

To run the java project, you have to have the editor with the class that
contains the static main function in focus to run it for the first time.
Later on just click the run button as it remembers where the main type is.
