Question:

When I attempt to use the Entity Bean Modeler Wizard in JBuilder 5 Enterprise, the wizard does not complete, but I receive the following error message in the message pane. Why is this occurring?

Answer:

This error would be caused if the jdbcx.jar file was missing or corrupted. It should be located inside the \jbuilder5\lib folder. If this file does not exist, you should either reinstall, or extract it from the CDROM:\alt_setup\jbuilder5.zip file.
