Trying to make a jar file double click/run from desktop

[silverglade]

Hi, I am having trouble making an executable jar file that I can email someone and have them run it on their desktop. The app has a gui window that will pop up, very simple app.

I did this on the command line


jar cf PushCounter.jar Pushcounter.class PushCounterPanel.class <enter key>

and it made a jar , but when I double click it, it doesn't make the GUI popup window


then I tried jar cf PushCounter.jar * <enter key> to include all the files in the directory relating to the program and no good.

Any help would be great. thank you. Derek

I have found making jar files a PITA. One thing I usually have problems with is the manifest file. Pointing out where you are going wrong over the net is nigh impossible as we are not there to see what you are doing. Are you reading a Jar tutorial? I suggest you read it and follow it very VERY carefully. If you skip or make a mistake in any of the steps the jar file will not be created correctly.

Create a new text file named manifest. Put in the following:

Main-Class: CLASSHERE

Put the name of your main class (the one with the main method) in place of "CLASSHERE".

Now open command prompt, navigate to the directory of your class files and manifest file, and enter this:

jar cvfm program.jar manifest.txt *.class

edit I will try the above thanks

Ok I made the jar file with the manifest with the correct contents. But the jar doesn't run on the double click. Here is the message from the command line upon making the jar.

C:\JAVA_PROGRAMMING_CODE\code1\pushcounter>jar cvfm PushCounter.jar Manifest.txt
*.class
added manifest
adding: PushCounter.class(in = 657) (out= 431)(deflated 34%)
adding: PushCounterPanel$1.class(in = 199) (out= 152)(deflated 23%)
adding: PushCounterPanel$ButtonListener.class(in = 1084) (out= 572)(deflated 47%
)
adding: PushCounterPanel.class(in = 1527) (out= 790)(deflated 48%)

C:\JAVA_PROGRAMMING_CODE\code1\pushcounter>



Contents of my manifest are this below


Main-Class: PushCounter

Did you end the manifest with a blank line?

Thank you. I just ended the manifest.txt with a few empty carriage returns to make a few blank lines. Saved it, and recompiled. Here is the log of what I did at the command prompt, thanks for helping. I want to get this running so bad LOL. It just won't run. Notice the "unable to load manifest info" when I even try to run it at command prompt.
