Here is an overview of the issue:
---------------------------------------------------------------------
Key: XDT-317
Summary: @web.servlet tag produces invalid web.xml for Servlets that employ
inheritance
Type: Bug
Status: Assigned
Priority: Major
Time Spent: Unknown
Estimate: 0 minutes
Project: XDoclet
Component: Web Module
Assignee: xdoclet-devel (Use for new issues)
Reporter: Stanford S. Guillory
Created: Thu, 20 Feb 2003 10:55 AM
Updated: Thu, 20 Feb 2003 10:55 AM
Environment: Windows 2000/Windows NT/JDK 1.4.1/Tomcat 4.1.18
Description:
If you have a servlet class that extends another servlet class, rather than
HttpServlet directly, and you utilize the @web.servlet and
@web.servlet-mapping tags in both the base class and the child class servlet, xdoclet
will attempt to generate *two* <servlet> tags for the derived servlet class, one
erroneously using the servlet name for the base servlet class.
Example:
/**
* @web.servlet name="BadCode"
* @web.servlet-mapping url-pattern="/badcode"
*/
public class BadCodeServlet extends HttpServlet {}
/**
* @web.servlet name="FilteredCode"
* @web.servlet-mapping url-pattern="/filteredcode"
*/
public class FilteredCodeServlet extends BadCodeServlet {}
The following entries will be generated in the deployment descriptor (web.xml):
<servlet>
<servlet-name>BadCode</servlet-name>
<servlet-class>coreservlets.ch03.BadCodeServlet</servlet-class>
</servlet>
<servlet>
<servlet-name>FilteredCode</servlet-name>
<servlet-class>coreservlets.ch03.FilteredCodeServlet</servlet-class>
</servlet>
<servlet>
<servlet-name>BadCode</servlet-name>
<servlet-class>coreservlets.ch03.FilteredCodeServlet</servlet-class>
</servlet>
This deployment descriptor is not valid since a duplicate servlet-name is used, and
app servers will reject it.
