Unable to configure json with spring - Request method 'GET' not supported - ajax

Question

I'm not able to correctly configure json support with Spring 4.0.4. A json request results in:
org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping.getHandlerInternal(246): - Looking up handler method for path /equipments/datatable.json
org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver.resolveException(134): - Resolving exception from handler [null]: org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported
org.springframework.web.servlet.mvc.annotation.ResponseStatusExceptionResolver.resolveException(134): - Resolving exception from handler [null]: org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported
org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver.resolveException(134): - Resolving exception from handler [null]: org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported
org.springframework.web.servlet.PageNotFound.handleHttpRequestMethodNotSupported(198): - Request method 'GET' not supported
I have an applicationContext.xml and a my-servlet.xml:
web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/conf/applicationContext.xml
/WEB-INF/conf/my-security.xml
</param-value>
</context-param>
<servlet>
<servlet-name>losap</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/conf/my-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

Controller
#Controller()
#RequestMapping(value = "/equipments")
public class EquipmentController extends BaseController {
#RequestMapping(value = "/datatable.json", method = RequestMethod.GET, headers = "Accept:*/*", produces = "application/json")
public #ResponseBody Equipment getEquipmentsDatatable(Model model) {
Equipment e = new Equipment();
e.setEquipmentName("Lathe 123");
e.setEquipmentNumber("12345TTY");
e.setId(89L);
return e;
}
}
jQuery
$.getJSON($('#ctxtrelurl').val() + 'equipments/datatable.json', function(e) {
console.log(e.equipmentName);
});

I have a feeling it has something to do with having two separate context config. files. Any pointers will be greatly appreciated.

ok, my guess is, that spring doesn't map /datatable.json properly because of the "." I had similar problem at mapping this:
#RequestMapping(value="/somestuff/{fileName:.+}"
i had to put :.+ so spring can properly map the url.
spring seems to truncate ".something" in this case. I actually don't know if it's the case on regular mapping, without #PathVariable. But you could try to map your URL without the dot and check if it will help
And that's why spring try to call the {equipId} function, that is waiting for PUT request. That's why in the response header you see : allow:PUT
