We don't need to stop running project due to server side datas changes

Question

How to do server side datas changes may be effect or update by browser's refresh in GWT projects ? Browsers may download js files of client side , but not server side. When a project is bigger and bigger , that may consumes many times of us. We also wait js files downloading times. One or two times were not problem. But if we changes small things and we want to see it's effects urgently , we will stop server again , re-run the project again , wait js file downloading time , reLogin again and so on. So , I really want to know how to do. Any suggestions would be appreciated. Thanks for reading my question patiently...

Answer 1

There's a "Restart Server" button in the DevMode window (in the Google Plugin for Eclipse it's a pair or swirling yellow arrows).

It'll restart the webapp, reloading the compiled classes from WEB-INF/classes and JARs from WEB-INF/lib.
If you're using Eclipse, it should already be configured to compile classes to that WEB-INF/classes folder so it should Just Work™.

My problem can solved with JRebel but I want to know is another way because it is not free tool :) .

It is awesome tool. You can add it your eclipse as plugin and add it's nature. If you run your project with it's console you can get always update datas of client and server side datas by saving your class or xml or any other files (I mean as I know ). If you want to test with it , guide is here.. JRebel for Eclipse That may be helpful for you...

To see the immediate changes you can copy your js files and paste it in your target folder of entrypoint project. And a browser refresh will suffice. Sometimes clearing of browser cache also required.

This might not be a classy solution but it will reflect the changes and in cases where you don't want to restart the server again and again to check whether it works or not.
