Class AbstractNoOpServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          com.atlassian.core.servlet.AbstractNoOpServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public abstract class AbstractNoOpServlet
extends javax.servlet.http.HttpServlet

NoOpServlet is a dummy servlet used only to provide a servlet mapping for url patterns that dont have any. This is necessary as some application servers like WebSphere 6.1.0.5 returns a 404 if there are no mapped servlet before applying filters to the request which could potentially change the URL mapped to a valid servlet. For example, the URLRewriter filter does this. Hence this dummy servlet should never handle any requests.

If this servlet receives a request, it will simply log all relevant information from the request that may be of help in determining why the request was received, as this would not be the desired result.
