This error is likely to be the problem:

The Web. xml file has versions 2.3, 2.4, 2.5, and 3.0, which have a very important configuration difference:

This can be configured in the servlet version 2.5, where multiple URLs are mapped to the same servlet. Specific as follows.

<servlet-mapping>

<servlet-name>servletName</servlet-name>

<url-pattern>/index</url-pattern>

<url-pattern>/login</url-pattern>

</servlet-mapping>

Not in 2.3 or 2.4.
