Alas neither solution worked. When I looked at the registry (as David suggested) there was no CLASSPATH entry for the Java VM (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM). In fact I searched and didn't find anything related to IE or Java that included a classpath.
I tried Adrian's suggestion of changing "Program Files" to "Progra~1", but that didn't resolve anything either. Here's what I am using: IE6, JDK 6 update 21, POI 3.6. Is there something about JDK 6 update 21 that is incompatible with POI? Any other suggestions will be happily accepted. Thomas
