How do I upgrade the JVM for ColdFusion on Windows?

  1. Download and run installer from http://java.sun.com/javase/downloads/index.jsp
  2. Open the jvm.config, the file which is typically within the ColdFusion directory within \runtime\bin. Locate the line that starts with java.home= and make a copy of the line. Comment out one of the lines by placing a # at the beginning of the line, this will allow you to easily revert if necessary.
  3. Update the other java.home= path to reflect the new JRE path, for example

    C:/Program Files/Java/jdk1.6.0_19/jre

    So it should look something like this:

    Note: The paths are forward slashes.

  4. Restart ColdFusion and the new version should be listed in the System Information page of the ColdFusion admin.
