I'm having a problem with displaying a string in jsp view. A a web framework I'm using Spring MVC.
The view (return.jsp) is like that:
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>FredomWings</title>
</head>
<body>
<b>Result -></b>
<p>${currentValue}</p>
</body>
</html>
The controller looks like that:
#RequestMapping(value="balance")
public String getBalance(Model model) {
model.addAttribute("currentValue","alalal");
return "return";
}
What is the reason for which in the jsp page only Result -> without any value is displayed?
I am trying to bind a list to drop down in JSP. Below is my controller and JSP.
Controller:
#Controller
public class WeatherServiceController {
#Value("#{'${countryList}'.split(',')}")
private List<String> countries;
#ModelAttribute("CountriesList")
private List<String> getCountries(){
System.out.println(countries.size());
return countries;
}
#RequestMapping(value = "/getweather", method=RequestMethod.GET)
public ModelAndView getWeather(){
Place p = new Place();
ModelAndView mav = new ModelAndView();
mav.addObject("place",p);
mav.setViewName("home");
return mav;
}
}
JSP:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Weather Service Client - Home</title>
</head>
<body>
<h2>Welcome to Weather Service</h2>
<form:form modelAttribute="place" action="getWeather">
<table>
<tr>
<td><form:label path="country">Country:</form:label></td>
<td>
<form:select path="country" items="${CountriesList}">
</form:select>
</td>
</tr>
</table>
</form:form>
</body>
</html>
But I am getting error like "Type [java.lang.String] is not valid for option items". Country list is not coming in jsp page. Please help me what I did wrong here.
It is working now.
I have added below line in jsp page.
<%# page isELIgnored="false" %>
I thought by default "isELIgnored" is set to false, so I haven't included earlier. After including this page is binding list result.
my data, which I try to pass from my controller to the view is apparently ignored. The console doesn't output any errors. Can somebody point me to the apparently obvious mistake I did?
Controller
#RequestMapping("/notes")
public String index(ModelMap model) {
String test = "Hello Felix";
model.addAttribute("hello", test);
return "notes";
}
View
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# page contentType="text/html; charset=UTF-8" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Notes</title>

<body>
<h1>${hello}</h1>

You need to return the model, something like the following should work:
Map model = ...
model.put(name, value);
return new ModelAndView(view, model);
I Have created simple mvc CRUD. All works fine except search page.
Im getting errorr as follows:
HTTP Status 500 - Request processing failed; nested exception is org.springframework.dao.EmptyResultDataAccessException: Incorrect result size: expected 1, actual 0
Controller page is:
#RequestMapping(value="/search")
public ModelAndView search(){
return new ModelAndView("search","command", new Emp());
}
#RequestMapping(value="/jsp/searchemp",method = RequestMethod.POST)
public ModelAndView search1(#ModelAttribute("name") Emp emp){
String name = null;
name = dao.searchname(name);
return new ModelAndView("searchemp","name",name);
}
Search.jsp:
<%# taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>z

Add New Employee
jdbctemplate query:
public String searchname(String name) {
String query = "select * from Emp99 where name=?";
Object[] inputs = new Object[] {name};
String empName = template.queryForObject(query, inputs, String.class);
return empName;
}
Dont know what goes wrong.
help me.
in order for jsp to consume an bean , your controller method should return data,in your jsp you are trying to utilize
{String.id} and {emp.id} which is never passed from the controller method search1.so you need to add your beans to a model and
return the page like this.
#RequestMapping(value="/jsp/searchemp",method = RequestMethod.POST)
public String search1(#ModelAttribute("name") Emp emp,Model model){
model.addAttribute("emp",emp); //passing the model name and the bean ,
//model.addAttribute("name",anotherBean); //you can add many attributes as you wish.
return "searchemp";
}
now inside the searchemp.jsp you can utilize the emp bean like this.
{emp.id}
remove the {String.id} part. inside the searchemp.jsp which will not work.
When a file is selected it must set the fileName with path to a textField with path="inputFileName". I tried to below code which is not working as setFileName is not called either onClick nor onSelect.
Any pointers how this can be done will be great help to me.
