[Solved]Fatal Exception occured when running jar file [modified]

I used BlueJ to create the jar which I believe creates the manifest file for me.

I'm afraid I know nothing about BlueJ so you need to go to the documentation to check it out. Alternatively you could deconstruct the jar file and check the files yourself.

This is the content of the manifest file:

Main-Class:MainWindow

Sorry, that looks OK, I'm not sure what else to suggest.

I added String[] args to the args of main () and it works.

Interesting; I actually wondered about that yesterday, but did not bother to test it out. To paraphrase Sherlock Holmes: "When you have eliminated the impossible, whatever remains, however improbable, must be the answer".

It sortof makes sense. Java apps are capable of processing arguments, altough they're infrequently used on Windows. Another thing I forgot was that the first letter of a method is always lowercase. I had to rename Main (String[]) to main (String[]).

As with most things in IT. ;)

I had upgraded QuickBooks 2009 to 2010 edition for my dad. The conversion started off at taking four hours, then down t 2 and a half hours, down to twelve minutes then down to 3. The whole process took around 2 minutes.

Umm, I think maybe this belongs to an alternative thread. :confused:
