You tell JRebel which directory to monitor for class file changes by creating a rebel.xml configuration file. In order for JRebel to detect changes in the build output directory it must know where this directory is located. If there is a change to any of the class files in this directory, then JRebel will update the classes in the container’s JVM to reflect those changes. In Maven, this is the target/classes/ directory of your Java project. JRebel works by monitoring the directory that contains the class files that are produced as part of a build.

JREBEL CONFIGURATION ECLIPSE CODE

In order to enable developers to be more productive, we decided to try using JRebel, a tool created by ZeroTurnaround that allows developers to see the effect of their code changes immediately. It is important to get quick feedback when working in order to maintain flow and productivity, and this wait time clearly violates that principle. This means that after a developer makes a change to the code, they must wait at least this long (in addition to the amount of time that it takes to get to the correct context in the application to test the change that they are going to make) to see whether the changes that they made achieved the desired result. This application server takes about 1.5 minutes to start. Change sth in a Java class or a JSP/ JSF file and save the file.On our current project, we are using a JBoss application server to host the services that the application needs to function.They describe the configuration in their installation instructions under Step 3.Īfter following these instructions, JRebel should be ready to work with our projects. JRebel recommends to additionally configure the Eclipse debugger in order to ignore synthetic methods.

It is already added to our parent project POMs (in the env-development profile), so all you have to do is to update your SVN folders and rebuild the packages that you want to use with JRebel.Īdditional Eclipse debug configuration

There is a Maven Plugin available which automatically creates this rebel.xml for our projects. For additional files and directories a config file named "rebel.xml" is required that describes these paths. JRebel has to know which class and resource files it should watch for changes.

Add the above line (with your JRebel path) to the VM arguments.Ĭonfiguration of development/build environment.

Double click on the server, a settings window will open.noverify -javaagent:c:\programme\javarebel-2.0.3\jrebel.jar Configuration of JBoss in Eclipse Replace the path with your individual complete path to the jrebel.jar file. Add the following line to your JBoss startup VM arguments.In version 2.2.1 you can also choose an installation jar which works quite nicely.

Copy the license file (*.lic) to the JRebel directory.

Unpack the zip to an arbitrary directory.

Luckily, we could convince them of our projects and got free one-year licenses for the OSS-committers at Max Planck Digital Library. JRebel is not free, but supports Open source Projects. This table shows what you can now do without a complete redeployment. It watches for changes in the class and resource files and maps them directly to the application server. JRebel is a great tool that bridges this gap. Unfortunately, Eclipse and other development environments do not support incremental hot deployment in combination with different application servers. This can get very time-consuming and annoying. Whenever you make a change to your Java code or your JSP/ JSF page, you have to rebuild and redeploy the complete application in order to see or debug the changes.
