## Saving the relationships together with a catalog

You can save the relationships by clicking OK on the Pre-join Editor toolbar. Note that the pre-join information won't really be saved to disk until you save the catalog. After you have saved the catalog, you can then use the just created pre-join to develop reports.

Notes:

- If you have made joins and defined at least one path, you can click OK to close the Pre-join Editor window.
- If joins have been made but no path defined,
  - If there are no join loops among the joins: after you have clicked OK, a default path named Path1 which includes all the joins you have made will be defined by JReport Designer. A message box will then be displayed to ask whether you accept the default path (click Yes), or you can modify the default path (click No).
  - If there are join loops among the joins, after you have clicked OK, the Save Pre-join Path dialog will appear for you to define at least one path.
