Resolving The Problem

Modify the web.xml and comment out the ipcsystem servlet and servlet mapping.

maximo\applications\maximo\maximouiweb\webmodule\web-inf\web.xml

Take out the ipcsystem servlet or comment out the XML tag.

<!--
<servlet>
<servlet-name>ipcsystem</servlet-name>
<servlet-class>psdi.webclient.servlet.IpcClientServlet</servlet-class>
</servlet>
-->
.....
<!--
<servlet-mapping>
<servlet-name>ipcsystem</servlet-name>
<url-pattern>/servlet/ipcsystem</url-pattern>
</servlet-mapping>
-->

Rebuild the maximo.ear, and restart the application server
