Spring Themes not working with REST - spring

Question

I have been trying to solve this problem for several days now and I also couldn't find any posts in forums with a similar problem. I have Spring Theme working well when I have the servlet mapping url-pattern as *.html in the web.xml file. However, if I change the url-pattern in the web.xml file to forward slash, so that the default servlet handles all requests and that the URLs can look like REST URLs, then I use to get NO MAPPING error, which results in not able to display the css settings for web pages. The NO MAPPING warning that I get use to get is as follows:
WARN http-apr-8080-exec-6 (DispatcherServlet.java:947) - No mapping found for HTTP request with URI [/MyApp/themes/default.css] in DispatcherServlet with name 'spring'.
But upon the mapping issue being solved by adding to my Spring servlet configuration file:
<mvc:default-servlet-handler />
another problem has arisen: Now, upon the application being started and prior to any operations, the use of clicking the Theme choice prior to any REST operation works well. It all works fine displaying the correct Theme. In fact, if I go via the normal Controllers (without REST) and do non-REST operations, everything continues to work as normal and I can switch between Themes. However, upon going via REST, and upon clicking on a Theme and even though it returns the same view name as the normal Controller would return, I get the following error in the browser and strangely with no console (debug) messages being reported:
HTTP Status 405 - Request method 'GET' not supported
type Status report
message Request method 'GET' not supported
description The specified HTTP method is not allowed for the requested resource (Request method 'GET' not supported).

And finally, my Theme properties files are location in
LiveAppSpring\src\main\resources
with the contents of all Theme properties files having the following pattern:
css=themes/default.css
AND to be safe, I have my css files duplicated in all 3 directories:
LiveAppSpring\src\main\webapp\resources
LiveAppSpring\src\main\webapp\resources\themes
LiveAppSpring\src\main\webapp\themes
Any directions would be appreciated.

Answer 1

I expect that /MyApp/themes/default.css should deliver default.css. But this is a resource file, and you mapped them by
<mvc:resources mapping="/resources/**" location="/resources/" />
So the right request url would be /MyApp/resources/default.css (assuming that the default.css is located in webapp/resources/default.css)
