I am using Spring framework.
Here is my controller:

Java

@RequestMapping("/com/index.do")
public String index(ModelMap model) throws Exception {
	MyClass obj=new MyClass();
	model.addAttribute("obj",obj);
	return "/com/index";
}

Here is my view:

HTML

<%@page contentType="text/html; charset=UTF-8" pageEncoding="ISO-8859-1"%>
<%@page import="org.springframework.ui.ModelMap" %>

<%
	ModelMap model=new ModelMap();
	Object obj=model.get("obj");
%>

In here obj is null.
In this case, how to retrieve that obj in view?
Note: I need to use in jsp tag (<% %>), not like this:

HTML

${obj}

Thanks!

You need your controller method to specify the "view" itself. So the return value should be a String that corresponds to the view name for aaaa.jsp. You can then add the map to the model and it will be available in the JSP. Here is the sample code:

C#

@RequestMapping(value = "/forgotPWD",params="username", method = RequestMethod.POST)
public String forgotPassword(@RequestParam(value = "username", required = false) String username,
         Map<String, Object> map, Model model) {
    [snip]
    map.put("forgotUser","Mail has been sent to your mail address");
    model.addAttribute("userMap", map);
    [snip]
    return "message.jsp"; // or just "message" depending on Spring settings
}
