Problem with java under linux

[Stefano Bianchi]

Ciao,

I need to start a java form compiler from linux.
The script that comes with the program simply says (after some
checks):

java -classpath Packager.jar:Fi ller.jar -jar EPT.jar

However, if I run it, I get:

java version "1.2"
gij (GNU libgcj) version 3.2.2 (Mandrake Linux 9.1 3.2.2-3mdk)

I guess that the error is in the fact that the command is ignoring the
-jar option, so that the EPT.jar is not read.
Java version and linux system are written on the log. How should I
translate the command line to get it working?

Thanks,

Stefano

Do you have any special reason for using GCJ? I'd strongly suggest
going and downloading Sun's JDK v1.4.2 for Linux if you don't.

If you do have Sun's Java installed, check your PATH statement, and
ensure that the path to Sun's Java appears before the GCJ Java Runtime
(use "which java" to find out).

HTH!

Re: Problem with java under linux

Thank you Brad!

I had Sun java installed, but it was not in my path.
I simply changed the script to run the Sun java bin instead of gjc and it works!
Maybe I should replace Sun java to gjc as a default...
