Updating an existing ITP/OnLine Web Application on WebSphere

Open the web administrative console and select Applications > Enterprise Applications. Select the application 'itp' and click the button Update.

In the dialog that follows choose to replace the entire application. Similar as to deploying, select the file itp.ear that is included in the ITP/OnLine installation package. Again, enter "itp" as the context root.

Then complete the wizard, which contains a number of follow-up screens. The default settings on these follow-up screens are normally all right.
