hi,
i am doing one sample application in hibernate with struts .i kept one jsp welcome file in web.xml with welcome file list.in struts-config.xml,i mapped the action path in jsp to one Action class which extends struts Action class.When i am running the tomacat server its perfectly working.and welcome file is displayed.But on submitting following error is given in browser.
"HTTP Status 500 - No action instance for path /search could be created"
Attaching the welcome file and struts-config.xml:
1.web.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

</welcome-file-list>

2.struts_config.xml:

<forward name="sucess" path="/sucess.jsp"/>
</action>
</action-mappings>
</struts-config>
3.jsp file:

<body bgcolor="lightgreen">

id:<input type="text" name="txt1"/>
<input name=button type=submit value="Click">
<input name=button type=reset value="reset">

4.Action class:

import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.log4j.Logger;
public class SearchAction extends Action
{
private static Logger log = Logger.getLogger(SearchAction.class.getName());
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest req,
HttpServletResponse res)throws IOException,ServletException
{
HttpSession session=req.getSession();
log.info("In Search Action");
Search se=(Search)form;
try
{
String name=SearchFascade.getSearchName(se);
session.setAttribute("name",name);
}
catch(DAOException daoexception)
{
daoexception.printStackTrace();
//return mapping.findForward("failure");
}
return mapping.findForward("sucess");
}
}
please give a solution.

due to securith issues, the java and sun should not be used as the package names. That is the not the starting word in the package.
for ex java.xyz ----- error
xyz.java or xyz.abc.sun ------- it's ok
for ex java.xyz ----- error
xyz.java or xyz.abc.sun ------- it's ok

There's also another problem. You're missing some important stuff in your web.xml file. Your servlet stanza should look like this:
