Servlet issue in 6.1 upgrade (from 5.6.1)

Hi,

I'm working on 5.6.1 to 6.1 upgrade. I'm facing issues with few custom servlets (these servlets are working fine in current 5.6.1).

My servlet looks like 

@Component(label = "The Search Servlet.", description = "Servlet for Search Process", metatype = false, immediate = true) @SlingServlet(generateComponent = false, paths = {"/bin/XXXX/servlet/search"}, extensions = {"html"})public class SearchServlet extends AbstractPostServlet {

.

}

but this servlet status is  'satisfied' in the Felix console. So I have modified the above servlet to

@Component(immediate = true, metatype = false)
@Service(Servlet.class)
@Properties({
    @Property(name = "sling.servlet.paths", value = "/bin/XXXX/servlet/search"),
    @Property(name = "sling.servlet.methods", value = "POST") })
public class SearchServlet extends SlingAllMethodsServlet {

.....

}

now servlet status is 'active' but still I'm seeing the same error  ( and in this case I'm seeing the request in the Felix console 'recent requests').

Error:-

on the page

Error while processing /bin/XXXX/servlet/search

Do you have any idea on this?

Thanks in advance for helping on this.

As @Scott mentioned

Adding only @SlingServlet(paths="/bin/mySearchServlet", methods = "POST", metatype=true) will make the servlet to work even in 6.1: Example: http://adobeaemclub.com/news-component-in-aem-using-guardian-news-api/

Take a look at similar reported issues, it might help you

To rule out JCR issue in your CQ version - try placing the an AEM 6.1 example Servlet  package for testing purposes.

You should get this result: 

This is using Path and posting data to a Sling Servlet. If you can get this working - it will rule out some sort of configuration issue. 

Install the 6.1 Servlet package here:

Make sure you install the 6.1 package and then let us know if that works and you get the same result as the above illustration.

    Have you verified if Sling is resolving your servlet correctly or not - http://localhost:4502/system/console/servletresolver ?

            Hi Are you modifying any jcr content using that servlet ? If so can you check ACL on that content

    Yes - looks like something is wrong - the return JSON is parsed and should be Filed by Scott Macdonald (or what ever your first and last name was)

    In this example - if you invoke in Chrome - are you seeing a 200 HTTP value or another value?

    Yeah, status code is 200 and response is {"date":"","firstname":"","address":"","city":"","cat":"Home","details":"","id":"40a4e66a-e90c-4586-8491-87123436f3a4","state":"Alabama","lastname":""}

    Hi ManiKumar, Thanks for your response, no I'm modifying any JCR content in my servlet, it is just 'response.sendRedirect' with some query parameter in the url.
