1 1  You'll now run your WO Application and get a glimpse at one of the coolest features of Eclipse.

3 -1. If you want to run your WO Application, you can right-click/ctrl-click on the project name, "Run As" => "WOApplication". But Run doesn't give you some of the cool features that you really want. What you'd really like to be able to do is make changes to your source code WHILE you're running and see them reflected in the running app, so don't click Run :)

On the icon bar of Eclipse, in the second set of icons, there is an icon of a Bug with an arrow next to it and a Play button with an arrow next to it. These are your Debug and Run buttons. If you click the down arrow next to the Debug icon, you will see a list of recent run configurations to choose from. If you want to rerun the last configuration, you can just click the debug icon itself. Run works the same way.

72 -1. Let's check out Hot Code Replacement. Switch back to Eclipse and leave the app running. Go to the Java tab of Main.wo and change the definition of now() to return a specific date and save. The Eclipse incremental compiler will now compile the changed method and replace it on-the-fly into the running application.

It is not able to replace structural changes to your code ~-~- added methods, removed methods, added fields, or removed fields. But most any change INSIDE of method works fine. You will find this to be an enormous productivity boost over the usual run, navigate, stop, fix, run, navigate, stop, fix cycle. Now it's run, navigate, fix, reload.
