Howto Modify Manifest.mf? Howto modify MANIFEST.MF in Studio Creator 2

[uapconsole 0]

My specs: Studio Creator 2 running on Windows XP Home edition, 2.4/512MB Dell workstation. Java SE Hello, I am attempting to compile a single Java file into an executible JAR file. I have no problem doing this. However, when I attempt to run the JAR file, I receive the following error: Error window header: "Java Virtual Machine Launcher"Contents: "Failed to load Main-Class manifest attribute from C:\....Swinger.jar" ---------It is a simple Swing example. It runs fine from the IDE. Furthermore, I know that I just need to define a Main-Class header in MANIFEST.MF. However, it is a read-only file, how would I modify this file? Thank You all in advance , - Demirelli

A jar file is just a .zip file, all you need to do is extract it with winzip and change the contents of the file
