  1. make sure you have JRE installed
    should be located at C:\Program Files\Java\jre6(or jre7)
  2. open cmd prompt and navigate to the directory where the file is located
  3. then type the command java -jar filename.jar (use your jar fileneme) or just double click the jar file

apreciate ur response
ive installed jre7 and yes i tried it in command prompt as u written it worked fine but when i m double clicking it is not working!!

ive set my class path as
PATH as variable and .;c:\program files\java\jdk1.6.0_01\bin as value
u mean to add the same but instead of jdk to put jre7's path

sorry i mean i set my environment variables as
PATH as variable and .;c:\program files\java\jdk1.6.0_01\bin as value
u mean to add the same but instead of jdk to put jre7's path

you have a talking jar file? now that's curious.
or do you mean that when you try running it by double clicking, it shows an error message?
if so:
1. read the above answers
2. try the possible sollutions provided there
3. if that doesn't work, consider starting a new thread, in which you specify what error message was shown and what you've tried.

(environment settings ok ... manifest file correct ... stuff like that)
