# Updating Libraries with Service Packs

After you install a BEA service pack that includes library updates, you must update the libraries in page flow web projects that you developed with an earlier version of WebLogic Workshop. For example, WebLogic Workshop 8.1 Service Pack 2 contains page flow library updates that were made since the initial 8.1 release.

To update the libraries for your page flow web projects:

1. In the WebLogic Workshop IDE, open the application you want to update.
2. In the Application pane, right-click the web project's root directory and choose Install > Web Project Libraries...
3. On the Install dialog window, the Libraries box should be checked. Also look at the selections in the Resources category. By default, the WEB-INF/validation*.* files may be checked, but the other resources are unchecked. It is important that you not allow the Install operation to overwrite resource files that you customized for your project, such as the root-level Controller.jpf and index.jsp files.
4. When you are ready, click the Install button.
5. After the updates have been made, click the Close button.
6. Repeat this process for other web projects in applications that you developed.
