printWriter() error
Hello,
I am very new to spring and have just been put on a project with an existing spring web application. I was also told the people who wrote the app did not know how to properly implement spring. Anyways I am trying to to setup a very simple controller (hello world) in the existing environment. I am getting an error and am not sure how to go about resolving it.
I am getting a 404 on the jsp and tomcat is showing a printWriterI() error. Below is the code, and the error:
JSP:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<head>
<title>merge test</title>
</head>
<body>
${message}
<p>This is a test of the emergency broadcasting system!</p>
</body>
</html>
Controller:
@Controller
@RequestMapping("/gcap/merge")
public class MergeController {
private static final Logger log = Logger.getLogger(MergeController.class);
@PreAuthorize("isAuthenticated()")
@RequestMapping(value = "mergeData", method = RequestMethod.GET)
public ModelAndView mergeData(){
log.info("GOT TO MergeController");
String message = "MERGE MY DATA";
return new ModelAndView("mergetest","message",message);
}
}

I figured this one out. My jsp was not being deployed to the correct location.
