issue while running a jar file in unix, but the same works fine in Windows

[deepak buddineni]

I have created jar file for my project called MyJar.jar .

1)When running in windows:
(C:\Users\Desktop\MyJar.jar has all the dependent jars in C:\Users\Desktop\testlib\)

So i run the program using the command :
C:\Users\Desktop> java -cp C:\Users\Desktop\testlib\*;C:\Users\Desktop\testlib\MyJar.jar com.abc.MyMain

The program runs absolutely fine!!!

2)When running in Unix:
/tmp/test/lib/MyJar.jar has all the dependent jars in /tmp/test/lib/*

So i run the program using the command :
/tmp/test > java -cp /tmp/test/lib/*;/tmp/test/MyJar.jar com.abc.MyMain

I get this error:

$ java -cp /tmp/test/lib/*;/tmp/test/MyJar.jar com.abc.MyMain

The path separator in Linux is colon ( : ), not semicolon ( ; ).

The semicolon separates one command from another, much like it separates one statement from another in Java. That's why you got

-ksh: /tmp/test/MyJar.jar: cannot execute [Permission denied]

at the end.

You first tried to execute java with only one of your jar files, and then after that you said, "next, execute the other jar file."

Yes sir.It works now.
