What configuration management / version control options are available when developing with JBuilder?

Integrated Version Control is a feature of the Enterprise Versions of JBuilder.

For versions 1,2,3 (Windows) - Borland shipped the PVCS Version Control System.

JBuilder 3.5 contains a sample integration with CVS, JBuilder 4.0 includes CVS

For JBuilder 3.5, There are some OpenTools that are compatible with all versions (Foundation, Professional Enterprise) that can be used to integrate with Source Control. One example is the Visual Source Safe Addin

If you wish to use a different Source Control system, all versions of JBuilder are "file-friendly" in that JBuilder stores all Java Source files as normal text files and is aware of when a file is changed from an external program.
