Disable jar packaging and signing for your build.

1. Right click on the project, choose Properties.
2. Choose Build | Packaging and make sure "Build Jar after compiling" is not checked.
3. Choose Build | Deployment and make sure that "Request unrestricted access" is not checked.
4. Press OK to close the project properties dialog.
5. Press F6 to run your project and make sure it still runs.
6. Modify a file and try running it again with F6 to feel the speed . . .

For distribution packaging you may want to re-enable some of these options, but if your app works without them when you are in development mode and it speeds up your development, then disabling them for development is a good idea.
