Run the iwadmin command.
Where im-svr-base is the directory in which you installed Instant Messaging.
Running iwadmin updates the Instant Messenger .jar files. However, iwadmin does not update or reinitialize the Instant Messenger download page.
See the documentation for your web container for additional information. Also see the iwadmin man page for additional configuration options.
(Optional) After upgrading, if you want to reinitialize the Instant Messenger download page, run the configure utility again.
Reinitializing the download page overwrites any customizations you have made. If you choose not to reinitialize the download page, be aware that the product version on the download page and the product version in the Instant Messenger .jar files may differ.
See Chapter 1, Configuring Instant Messaging After Installation for more information.
