Getting JRebel Standalone

  1. Download the JRebel Standalone ZIP.
  2. Unpack the archive to a folder of your choice.

Getting your license up and running

  1. Find the jrebel-activate.jar file in the bin folder, right where you extracted JRebel. Run it!
  2. Fill out the form.
  3. Press Activate JRebel.

Got a license?

Press I already have a license in the activation window.

  • Activation code. Paste your activation code if you have one already.
  • License file from the hard drive. Point to your jrebel.lic file. You get this file via email when you purchase JRebel.
  • Connect to ZeroTurnaround License Management or an on-premises License Server. Enter your team URL and email. You get the team URL from your network administrator.

Generating rebel.xml

  1. JRebel requires an XML file to map your workspace to your deployed application.

Here is an example of a generated XML file:

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.zeroturnaround.com" xsi:schemaLocation="http://www.zeroturnaround.com http://update.zeroturnaround.com/jrebel/rebel-2_1.xsd">
<classpath>
<dir name="C:/Users/user/workspace/spring-petclinic/target/classes">
</dir>
</classpath>
<web>
<link target="/">
<dir name="C:/Users/user/workspace/spring-petclinic/src/main/webapp">
</dir>
</link>
</web>
</application>

Did this work?

When building your application, rebel.xml should be included within the application archive.

  • In case of JAR files, rebel.xml should be included in the root folder.
  • When working with WAR files, the rebel.xml should be located within the WEB-INF/classes folder.
  • EAR files require a rebel.xml for each internal EAR module (that means JARs and WARs).

Enabling JRebel agent for your server

  1. Add JRebel to the JVM startup arguments. Read more here.


Good to know

Head over to the JRebel Manual to read more about running servers with JRebel.


Did This Work?

  • When building your application, rebel.xml should be included within your application’s archive.
  • When working with JAR files, rebel.xml should be located in the root folder (i.e. yourapp/rebel.xml).
  • When working with WAR files, rebel.xml should be located in the WEB-INF/classes folder (i.e. yourapp/WEB-INF/classes/rebel.xml).
  • When working with EAR files, rebel.xml should be located in each internal EAR module (that means both WARs and JARs as shown).

When successful, you will see the JRebel banner in the console right at server startup. This is what the JRebel banner should look like:
