  • open the file in a text editor, and remove the lines that look like this:
<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name> 
    <url-pattern>/webservices/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/WebServices/*</url-pattern>
</servlet-mapping>
