Passing Additional Arguments to the JVM to Control Mule

The Wrapper provides several properties you can set as described in the article on Java Service Wrappers.

If you want to pass additional arguments to the JVM that runs Mule, you can add wrapper.java.additional.n entries to the wrapper.conf file in the ${MULE_HOME}/conf directory, or you can pass the arguments at the command line by adding the -M switch.

For example, to set Mule’s encoding, you could:

  • Add wrapper.java.additional.1=-Dmule.encoding=ISO-8859-1 to the Wrapper configuration file.

  • Or you could add -M-Dmule.encoding=ISO-8859-1 to the Mule script at the command line.

    Example
If you add wrapper.java.additional.n entries to the configuration file, you must change each instance of n to a consecutive number, or Java does not parse the properties correctly.
