The file you need to run should end .class or .jar. If you don't have
such a file, you'll need to compile it first. You probably need a java
sdk rather than jre, although gcj might do the trick.
Then:
javac Switch.java
should make the .class file. (You may need to include the path to your
java compiler).
Finally:
java Switch.class
should run it.
Of course Switch may not be a runnable class, in which case you'll get
an error.

Hi,
I have a java program named Switch.java, I want to run it under

I need to install? I installed a package named
jre-1_5_0_11-linux-i586-rpm.bin, when I use command
java Switch.java
wrong information came out:
Exception in thread "main" java.lang.NoClassDefFoundError: SwitchI

Caused by: java.lang.ClassNotFoundException: SwitchI not found in

Then I used command yum install libgcj.so.7 , but it was not helpful.
I am a java newhand, any help will be appreciated, thanks!
