   As Kevin indicated a stacktrace would be needed to pursue this further.

You might start by reading  two papers I  wrote, by following the links 
ab the bottom of this email.

Actually DX was introduced in much earlier versions..  Brains a big 
foggy on this but I seem to remember that version 1 had the beginnings 
of DX.   I have never found any "depreciation" issues.  Only 
enhancements and extensions.

No not in the slightest..

Your problem may be that you are trying to use it in Eclipse and are 
therefore missing the correct class files.  This is a JBuilder ONLY 
component and should be used ONLY in JBuilder.

Hope that helps get us back on the right track..
