After you have checked a class or interface out of an external SCM tool's repository, and made changes to it in VisualAge for Java, you may want to compare the edition of the class that is in your workspace to a previous one in the SCM tool's repository.
If the automatic export step is successful, VisualAge for Java invokes the compare function of your SCM software program. If the export is not successful, confirm that you have checked the class out of the SCM repository. (If the file is checked in, the file status in the work directory is read-only.)
