| 1 | JRebel (previously called javarebel is a tool from [[ZeroTurnaround>>http://www.zeroturnaround.com]]). | ||
| 2 | |||
| 3 | It is a java library that makes it possible to change java code while running a project in WOLips and see the results without having to restart. It is a great timesaver. | ||
| 4 | |||
| 5 | If you are running Eclipse 3.4, you should have a look at the screencast from David Avendasora at [[http://www.wocommunity.org/podcasts/WOJavaRebel_Setup.mov]]. | ||
| 6 | |||
| 7 | If you are running WOLips 3.5.1 or bigger, you are lucky: the JRebel plugin is included in the current WOLips for there versions. | ||
| 8 | |||
| 9 | How to install and use JRebel | ||
| 10 | |||
| 11 | 1. Download you version from [[ZeroTurnaround>>http://www.zeroturnaround.com]] | ||
| 12 | 1. put the jrebel.jar somewhere nice, so you can use it in whatever project you are working | ||
| 13 | 1. Go to WOLips->Preferences->Install Software, add http:~/~/www.zeroturnaround.com/update-site/ | ||
| 14 | 1. Download the Jrebel Eclipse Integration and perhaps the JRebel Eclipse Debugger Integration from install new Software, | ||
| 15 | 1. Make sure you have checked the JRebel Plugin in WOLips if you download the newest version. | ||
| 16 | 1. Goto to preferences->JRebel, and point the Path to jrebel.jar to the jrebel.jar location from action 2. | ||
| 17 | |||
| 18 | You have now installed and setup the stuff that WOLips needs to know about the location of JRebel.jar. | ||
| 19 | |||
| 20 | How do you use it? | ||
| 21 | |||
| 22 | Well that has become very simple since the inclusion of Quinton Dolan's JRebel plugin in WOLips. | ||
| 23 | |||
| 24 | For a project in which want to use jrebel to change java code while running, go to the run configuration of the project, under the contextual menu Run As->Run Configurations. | ||
| 25 | |||
| 26 | In the Run Configuration of a WOApplication you will notice an extra Tab, called JRebel. | ||
| 27 | |||
| 28 | Select the tab, and check the check boxes to enable JRebel Agent and (eventually) Enable debug logging. | ||
| 29 | |||
| 30 | Start you project from the Run Configuration. | ||
| 31 | |||
| 32 | Suddenly, you will get messages about jrebel being loaded, and some extra information about what settings are available as extra arguments. | ||
| 33 | |||
| 34 | Start changing your java code on the fly: watch and start saving time. | ||
| 35 | |||
| 36 | Profit! (for the europeans: Extra Time Off!) |
