Just Try these Steps once again. Try it with a simple swing screen first. may be a frame.

Steps:

1. Put all class files in one folder. Note: The Main Class should be a public class.                           ----

2. Also add one file with any name and extension let us say manifest.txt

3. The file mentioned in step-2 should have the following entry

      Main-Class: MainClassName

4. Dont forget the newline after the Entry

5. Go to command propmt. Navigate to the folder and use the follwing command.

      jar -cfvm jardemo.jar manifest.txt *

6. The Jar File should be Ready

Hi Naveen,

Thanks,

Hi Jahangir,

See attached Manifest and JAR file, double-click on attached jar file it opens a Swing window....what santosh told is correct....observe attached files clearly to get right picture.

Hint: Use Eclipse (or some IDE) for creating the JAR file by supplying 'main class' file name in it. Then it directly creates Executable JAR.

I hope all your worries are gone :)

In the Manifest file after the main-class entry there should be a new line character. check that out. If there is no new line character it will fail.

Hi,
I have uploaded one utility called "JarBuilder".
Now you can easily create Executable Jar files.
You download that tool from completeJavagroup/files/java section.
and unzip that archive and double-click jarbuilderXXX.jar.
Then you select needed class files the you say create jar, it'll
search and list classes having main method.you select the main class
from that list and give the location and name of the jar file to be
created.
it is now very easy....
