here is the url-pattern in web.xml
<servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
Here is my controller
@Controller public class HelloController { @RequestMapping("/*.km") public String handleKm() { System.out.println("km ext called"); return "aaa"; } @RequestMapping("/*.jsp") public String handleJsp() { System.out.println("jsp pages called"); return "bbb"; } }

while accessing the url with http://localhost:8087/requestMapping/a.km , it is works, calls the handleKm() method.
but with http://localhost:8087/requestMapping/a.jsp , it should call handleJsp().but it does not work. result : HTTP Status 404 - /requestMappingExperiment/a.jsp.
why ??

If I chane the url-pattern from "/" to "/*" , although both method are called , but dont get to the appropriate pages.
May be the "org.springframework.web.servlet.view.InternalResourceViewResolver" is not working .

please help. I m new to SprimgMVC.
Thanks

I cant understand now, that the same code I did a copy-paste in a new web application.
And it works fine.

I tried the old one by deleting the application from C:\Tomcat 6.0\work\Catalina\localhost\oldProject
don't work.

Then I tried to run it on my friend's computer. But did not work.


Then I created a new project from the scratch. And just copy paste the same code from the old project.
And its just working fine.

May it be a virus effect ??? I cant understand.
Please share your experience.

session.isNew()true

Enumeration enm = session.getAttributeNames(); enm.hasMoreElements());false

Hi William Brogden. Thanks for your reply.
According to you I have tested like this :
System.out.println(session.isNew()); // true if(session.isNew()) { Enumeration enm = session.getAttributeNames(); System.out.println("has more elements : " + enm.hasMoreElements()); //false while(enm.hasMoreElements()) { System.out.println("element : " + enm.nextElement()); } }

Hi Bear!

Both servlets are in the same web-app. Infact in the same package.
The Redirect URL without a context path also works for me.
But I have tried with a context path also. But with no results.
String contextPath = request.getContextPath(); response.sendRedirect(contextPath+"/loginAuth");

Edit : for the second servlet
The SecondServlet is here.
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String name = (String)request.getSession().getAttribute("name"); System.out.println(name); }

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { HttpSession session = request.getSession(); session.setAttribute("name", "MyName"); response.sendRedirect("SecondServlet"); }

Here is the Second Servlet

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { HttpSession session = request.getSession(); String name = (String)request.getSession().getAttribute("name"); System.out.println(name); }

name=null , in the SecondServlet
Whats the problem?

what to put in view and what to put in controller, I really dont understand .
Would you please provide me some resource on that ?
Thanks .

<%request.removeAttribute("name"); %>
How could I perform this without using <%%> ?

Thanks for your quick reply.

Now is there any ideal way to populate data in a drop-down-list at the very first visit of a jsp page form ??

I was doing like this
ArrayList<String> stateList = request.getAttribute("stateList"); if(stateList ==null) { RequestDispatcher rd=request.getRequestDispatcher("myServlet"); rd.forward(request, response); } else { //iterate through the list }

<% RequestDispatcher rd=request.getRequestDispatcher("mypage.jsp"); rd.forward(request, response); %>
How the above code could be replaced with EL ? or Any other way ?
Please help.

class AAA<T1, T2> { void show1(AAA<T1, T2> a) { } void show2(AAA<?, ?> a) { } }

Please explain it . What is the difference between the two methods show1() and show2() ???
When to use the wildcards ?
Thanks.

The program gives the out put but with the missing first letter of every line.

Error :

The requested URL /schoolAutoSysV1/pages/ff.action was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

-------------------------------

The project is running on my local system. But after uploaded on the server its throwing the above error.
I think there is some problem connecting with the database
The databse i have used is mySql.

please help.

pages/admin/admin.jsp
pages/admin/success.jsp

admin.jsp
-------------------------------
<s:form method="post" action="/admin/admin.action"> <s:submit/> </s:form>


struts.xml
----------------------------------
<struts> <package name="admin" namespace="/admin" extends="struts-default" > <action name="admin" class="com.AdminLoginAction"> <result name="success">/pages/admin/success.jsp</result> </action> </package> <struts>

pages is the root namespace.
