I'm getting a java.lang.UnsupportedClassVersionError when I try to start the broker. What does this mean ?
The QPID broker requires JDK 1.5 or later. If you're seeing this exception you don't have that version in your path. Set JAVA_HOME to the correct version and ensure the bin directory is on your path.unmigrated-wiki-markup
