回答1:
Check that you have the environment variable JAVA_HOME defined and set to the root directory of your JDK (not just a JRE, which doesn't include javac)
回答2:
for anyone who googles this error when using xml beans (I was forced to maintain an old app that uses xmlbeans and got this error), use jdk 5 and not higher for xmlbeans and this error goes away
