Sun One Studio 3.0 EE Installation error

Encountered following error while installing Sun One Studio 3.0 EE :

For Tools Debugger ("Org.netbeans.modules.debugger.debug/1") failed :

This module depends on java package sun.tools.debug which is not loaded

( or not registered according to the versioning specification ).

Any help on this ?

Thanks
