1. Right-click your project node. Select Properties.
2. Enable Build > Compile > Compile on Save.
3. Disable Run > Deploy on Save.

Why Do This?

These options will avoid unintended redeploys, making your experience a lot smoother.

JRebel relies upon your IDE to do the compiling. JRebel reloads your compiled .class files and not your .java files. When you change code, JRebel pushes the changed classes and resources to the server without redeploying.

1. Restart your application server or Java application.
2. Change something in the application code and save.
3. Refresh the application in the browser to see the changes!
