Hi everyone,
I have made a Java project using Swing and JDBC. Now to make it run on another PC, i make a runnable JAR file of the project and simply run it on the PC.
The problem is it works fine ont the PC for some time and then suddenly stops working. When i restart the application, it again works fine.
Any idea why this error is occuring?
Please help...
Thanks in advance

Run the JAR file from the command line, using java -jar <jarfile>. My guess is that there is an exception that you don't see when you start the program by double clicking the JAR file.
