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.SlingServletResolv...  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);
        }
    }
}
