Recent Identity Manager versions might contain API changes. If you have modified .jsp files in your installation, you might have to update them when upgrading. You must update any JSP that was supplied by Identity Manager and changed during a deployment (or a custom JSP that uses Identity Manager APIs) to work with the new JSP structure and API changes for the target release.
For a detailed description of API changes, see the Identity Manager Release Notes for the release to which you are upgrading.
Use the inventory -m command (described on Identity Manager Assessment Tools) to identify any JSP modifications made in your deployment.
For more information about JSP customizations, see Chapter 11, Editing Configuration Objects, in Sun Identity Manager 8.1 Technical Deployment Overview.
