I am using following method in Controller
@ModelAttribute(“users”)
@RequestMapping(value = “/GetList.json”, method = RequestMethod.GET)
public @ResponseBody List getList() throws Exception{
List users = new ArrayList();
try {

User user1 = new User();

user1.setFirstName(“Vijayasekhar”);
user1.setLastName(“Duvvur”);
users.add(user1);

User user2 = new User();

user2.setFirstName(“Markus”);
user2.setLastName(“Rogosinsky”);
users.add(user2);

} catch (Exception e) {
return null;
}
System.out.println(“Exit GetList method ” + users);
return users;
}

and i am invoking using RestTemplate as follows

List list = template.getForObject(url, List.class);

When i am trying to print list its collection of LinkedHashMap objects instead of User objects

I am not understanding whats going on ..

I just uploaded new project zip. Old one had winzip only compression settings.

Erwin,

Yes something is wrong with the zip. I can open it only one of my laptops that has winzip.
I will upload updated zip Monday.

Hi,

Is the zipfile broken? I can see the file but i get errors when i try to extract. The JSONView.java is what i want to see, if i copy the code fragment i get errors. I would like to get it working!
thx for the tutorial

Chris,

I checked, the source and all the configs are there in the zipped up project. Google app project is not a “web application” project in eclipse. If you are building regular web app, start with a new project wizard and add the required configurations and libraries from the downloaded one by hand.

Thank you for the tutorial. I am trying to use your example to get REST working with Spring 3.0RC1 w/o Google. I tried to get the full project source as I could not get my code to work off the tutorial but the source is missing the source files and the XML files. Did I do something wrong? Thanks in advance and great job on the tutorial. I know I am close.
