How can I make own ActionServlet? with example
Answers were Sorted based on User's Feedback
You can make your own ActionServlet by extending
RequestProcessor class and overriding its methods. The
example is given below....
package com.visualbuilder;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.RequestProcessor;
public class CustomRequestProcessor extends
RequestProcessor {
public boolean processPreprocess(HttpServletRequest
request, HttpServletResponse response) {
System.out.println("Called the preprocess method before
processing the request");
return super.processPreprocess(request,response);
}
}
The following is web.xml file u should change it accoringly
<?xml version="1.0" encoding="UTF-8"?><web-app
version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-
app_2_4.xsd"><servlet> <servlet-name>action</servlet-
name> <servlet-
class>com.visualbuilder.CustomActionServlet</servlet-
class> <init-param> <param-name>config</param-
name> <param-value>/WEB-INF/struts-config.xml</param-
value> </init-param> <load-on-startup>2</load-on-

Answer / shaik baji
1)ActionServlet contains a set of methods which are invoked
by the container for processing the client request. If we
want to define our own ActionServlet then you
should "extends" our class
from "org.apache.struts.action.ActionServlet" class and
what ever the functionality we want to override of the
ActionServlet we should override that respective predefined
ActionServlet methods.
2)To invoke our own ActionServlet class instead of the
predefined ActionServlet class we should specify our own
ActionServlet class name in In "web.xml" file like as
follows:
<servlet-class>MyOwnActionServlet</servlet-class>
3)Then the container will invoke our own ActionServlet class
