# Updating Portal Libraries with New Service Packs

After you install a new service pack that includes portal library updates, you must update the libraries in the applications you have developed. Updating overwrites the existing libraries. To update your application libraries:

1. Shut down your server if it is running. In WebLogic Workshop, choose Tools --> WebLogic Server --> Stop WebLogic Server.
2. In WebLogic Workshop, open the portal application you want to update.
3. In the Application window, right-click the application directory and choose Install --> Update Portal Libraries.
4. If the service pack includes Commerce or Pipeline updates, right-click the application directory and choose Install --> Commerce Services and Install --> Pipeline Services.
5. After the portal application libraries are updated, a dialog box appears that lets you select Web projects in the application to update. Select the Web projects whose libraries you want to update, and click OK.
6. In the Application window, right-click the Web project directory and choose Install --> Update Portal Libraries.
7. In the Application window, right-click the Libraries directory and choose Add Library. In the Add Library window, switch to the <app>/APP-INF/lib directory, select all the files in that directory, and click Open. If you are prompted to overwrite existing files, click Yes.
8. If the service pack includes updates to Commerce or Webflow JSP tag libraries, right-click the Web project directory in the Application window and choose Install --> Commerce Taglibs and Install --> Webflow Taglibs.
9. Restart the server.
