public class SendErrorServlet
extends javax.servlet.http.HttpServlet

This servlet simply sends an error code. The only reason you might need such a thing is to override a servlet that has been deployed in a Library Module. Due to the way descriptor merging works for web.xml, you can not "turn off" a servlet which is deployed in a library's web.xml. There is not anything available in your web app's web.xml to turn such a servlet off. Therefore, the only thing you can do is override the servlet with one that sends errors (usually 404, which is what this servlet does. This servlet understands one optional init parameter named "errorCode", which should be an integer for the code this servlet should send. It defaults to 404.

For example, maybe a library module contains a servlet such as:

    <servlet>
      <servlet-name>SomeServlet</servlet-name>
      <servlet-class>org.foo.TheServlet</servlet-class>
    </servlet>
 

You can override this in your application's web.xml using the same servlet-name, like this:

    <servlet>
      <servlet-name>SomeServlet</servlet-name>
      <servlet-class>com.bea.p13n.servlets.SendErrorServlet</servlet-class>
    </servlet>
