Installing and Endorsing the JDK

Before installing Mule ESB, ensure that the host machine has one of the following Java Development Kit versions installed on it:

  • Standard Edition 1.6.0_26 (also known as JDK SE 6 Update 26) or more recent (including SE 7)

  • Enterprise Edition 1.6u3 (JDK EE 6 Update 3) or more recent (including EE 7)

You can download the JDK from here.

Be sure to set the JAVA_HOME environment variable on your system to point at the directory where you have installed your JDK, as in C:\Java

Endorsement

If you choose not to use one of the JDK options listed above for any version of Mule ESB, you must "endorse" that JDK with a proper implementation of JAXP (Java API for XML Processing).

To do this, download Apache Xerces and Xalan and drop the .jar files into the jre/lib/endorsed directory of your JVM (Java Virtual Machine). If that directory does not yet exist, create it.
