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

in that case, make sure you have your environmental settings and your classpath in your os set correctly.

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

i have created Runnable Jar file,when i clicked jar file,it says error

[stultuske]

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)
