Jar not WORKING FOR ANYONE BUT ME!!!!!!!! HELP

I've made many jars in the past and i keep having the same problem!

http://uppit.com/k040f20m1d6f/client.jar

Error: could not find the main class: client.class Program will exit.

This jar working for me, why wont it work for anyone else?

[Question: Can it be because me jdk is Complete Up to date?]

No. Where is client.class? Is it in the jar? Or is it only on your machine?

Is your class name: client.class or is it client? Client.class looks like a filename, not a class name..
If it were named client.class then the name of the class file would be: class.class and it would be in the client package.
Remove the .class from where you are specifying the class name.

The client file is uploadd into the jar file, ive mad jar files with command line and have gotten same problem, this time i used a 'jarmaker' and have the same problem, and the error has no .class, my friend typed it wrong when he sent it to me.

Try openning a command prompt and issuing the java command:
java -jar client.jar

Then copy the command prompt console with the error message.
On Windows: To copy the contents of the command prompt window:
Click on Icon in upper left corner
