Right now, I am trying to use Spring 3.1.0 since it fixed the js issue. But I got 400 Bad Request Error in Weblogic when clicking on the Create button. When running in Tomcat, the FormatAnnotationIntrospector is not used to handle the format annotations.

2) when I hit creat button I only get this error :

escription The server refused this request because the request entity is in a format not supported by the requested resource for the requested method ().

Please whoever had success with this example help me .
thanks.

I am developing a web application in Spring Framework. In simple words my application works with

Spring MVC RESTful JSON ajax jQuery. HOpe you understood by this.

To implement security i am struggling alot. Can u kindly Post a tutorial with sample code. That implements spring security for login validation with remember me option.

And if possible, every request must be checked.

Please help me.

I actually prefer a synchrounous in my app. Wonder if there is a way to do that. Currently, I'm using
$.getJSON("enrollment/get_info", { countryCode: "GB" }, function(myInfo) {
// something to do with myInfo
});

Jason

In JS:
$.getJSON("enrollment/get_info", { countryCode: "GB" }, function(myInfo) {
alert("myInfo = " myInfo);
});

In Controller:
@Controller
@RequestMapping("/enrollment")
public class EnrollmentController{
@RequestMapping(value="/get_info", method=RequestMethod.GET)
public @ResponseBody String getInfo(@RequestParam String countryCode) {
System.out.println("countryCode = " countryCode);
return "Your info";
}
}

In servlet-context.xml:
…

…

And I do have the following jars in my WEB-INF/lib
jackson-core-asl-1.6.4.jar
jackson-mapper-asl-1.6.4.jar

I'm using springframework 3.0.6

I can see the following in my tomcat log:
countryCode = GB
2011-11-06 10:24:47,601 DEBUG [DispatcherServlet] DispatcherServlet with name 'springAppServlet' processing GET request for [/myapp/spring/enrollment/get_info]

2011-11-06 10:24:47,607 DEBUG [DispatcherServlet] Successfully completed request

I can see that the controller was prossing the request, but just couldn't return back to the javascript caller since its alert() never shown.

The other interesting thing is that sometime the request couldn't even reseach the controller without changing any of code/configuration.

What's wrong? Do I need the java classes in org.springframework.samples.mvc.ajax.json from this sample for my controller? Currently I'm not using them for my controller.

Appreciate your help!
Jason

open the browser debugger and check what it shows you. Also, when you said "Nothing submitted to server" you already check the DEBUG messages and you are sure that "Nothing submitted to server", don't you?

After using sts, everything runs fine

I just tried this but when click Create button, nothing happened. Nothing submitted to server.

Anyone can help?

many thanks

Spring detects and invokes the JacksonConversionServiceConfigurer @Component when the application starts up. This BeanPostProcessor intercepts the initialization event for Spring MVC's AnnotationMethodHandlerAdapter, retrieves the default MappingJacksonHttpMessageConverter, and injects a custom Jackson ObjectMapper that uses our ConversionService.

Given that, how can one obtain a reference to the ObjectMapper to define additional customizations?

Specifically, I'm looking for a way to define what java class type is passed in to the deserializer. I want to define whether the controller attempts to parse a base or derived class.

I don't want to use polymorphism as I know at runtime which class a controller should expect. I'm sharing controller code between 2 apps that use different variations of the data types.

Is this possible? – to set the class type here:
@Valid @RequestBody ObjectType obj) {
to ObjectType or a subclass thereof via wiring or other startup config?
