sling.servlet.paths don't work in Servlet

Hello, AEM Community

I have the following issue:

I want to create a servlet which works with the following properties:

@Component(

   immediate = true,
   service = Servlet.class,
   property = {

   "sling.servlet.extensions=json",
   "sling.servlet.extensions=js",
   "sling.servlet.resourceTypes=sling/servlet/default",
   "sling.servlet.methods=GET",
   "sling.servlet.methods=HEAD",
   "sling.servlet.paths=/content/unified"
   }

)

public class UnifiedSettingsJSONServlet extends SlingSafeMethodsServlet {

...

}

But it activates on all paths, not only specified. If I delete "sling.servlet.resourceTypes=sling/servlet/default", it doesn't work at all. So, I think "sling.servlet.paths" is ignored and I don't know why. Do you have any ideas?

Use:

org.osgi.service.component.annotations.Component

AEM 6.3.

Thanks.

    Hi,

    You should not use extension if you are registering servlet by path.

    The servlet is working with "sling.servlet.resourceTypes=sling/servlet/default", because you registered as default servlet.

    There is a issue with path as well, you need to specify Execution path at http://localhost:4502/system/console/configMgr/org.apache.sling.servlets.resolver.SlingServletResolver  if you are registering servlet by path

    "sling.servlet.paths=/content/unified"

    Please check sample servlet aem63app-repo/SimpleGetGroup.java at master · arunpatidar02/aem63app-repo · GitHub

        Hi, arturl43391132 and  Arun Patidar,

        below is my servelt but when i am using http://localhost:4502/content/dam/html-content/test.html  this url it is not calling servelt i have added the path "/content/dam/html-content" in Apache Sling Servlet Configuration

        FYI , We have a business requirement to host static webpages from AEM. Our AEM version is the latest AEM as a Cloud Service - 6.5.


        I did try
        1. Unchecked "Enable For All Resource Paths" option in the Apache Sling Content
        Disposition Filter;
        2. Removed the blacklisted "text/html" configuration and unchecked Allow unknown mime types from SafeBinaryGetServlet(DamContentDispositionFilter)

        but nothing worked.
        let me know if you have better solution

        @Component(immediate = true, service = { javax.servlet.Servlet.class }, property = {
                "sling.servlet.methods=GET",
                "sling.servlet.paths=/content/dam/html-content",
                "sling.servlet.methods=HEAD",
                "sling.servlet.resourceTypes=sling/servlet/default",
        })

        public class CustomDAMSlingServlet extends SlingSafeMethodsServlet {
            private static final Logger log = LoggerFactory.getLogger(CustomDAMSlingServlet.class);

            @Activate
            protected void activate() {
                log.info("CustomDAMSlingServlet activated");
            }

            @Override
            protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response)
                    throws ServletException, IOException {
                try {
                    log.info("In the servlet");

                    response.getWriter().write("Hello, this is MyCustomServlet for /content/dam/html-content/test.html!");

                    log.info("CustomDAMSlingServlet: doGet method started");
                    // Get the path of the requested HTML file
                    String path = request.getRequestPathInfo().getResourcePath();

                    log.info("pathhhhhh: {}");

                    response.setHeader("Content-Disposition", "inline; filename=" + path);

                    // Read the content of the HTML file from DAM
                    InputStream htmlStream = request.getResource().adaptTo(InputStream.class);

                    // Set the content type
                    response.setContentType("text/html");

                    log.info("CustomDAMSlingServletttttt");

                    // Copy the content to the response
                    IOUtils.copy(htmlStream, response.getOutputStream());

                    log.info("CustomDAMSlingServlet: doGet method completed");

                } catch (Exception e) {
                    log.error("Error in CustomDAMSlingServlet: " + e.getMessage());
                    response.setStatus(SlingHttpServletResponse.SC_INTERNAL_SERVER_ERROR);
                }
            }
        }
