I am not sure what to suggest - it sounds as if there might be an issue with the Java installation on your system. It could be worth checking the CLASSPATH environment variable on your system and (if it is present) make sure it starts with
to ensure that the current directory is checked for Java classes. Also if there is a JAVA_HOME environment variable then make sure it points to where java has been installed.
Your best bet might be to use the "Java" command instead of "javaw" and do it from a DOS command box. That stops java being run in a separate process and leaves it reporting to the command window used to initiate it.. That way you have a better chance of seeing any error messages. It could also be worth checking in Event Viewer to see if there are any error messages being reported there.
