See this article - we cover that here: Creating a Mail List Sign Up Component for the Experience Manager Toy Store Site

The reason why I pointed you to this article is because you wanted to know why @SlingServlet did not work.

An important aspect to notice is the change on how an AEM Servlet is created. There is no longer @Service or @SlingServlet annotations in the org.osgi.service.component.annotations package.

In Maven Archetype 10 project, you defined a servlet like this:

@SlingServlet(paths="/bin/mySearchServlet", methods = "POST", metatype=true)

public class HandleClaim extends org.apache.sling.api.servlets.SlingAllMethodsServlet {

private static final long serialVersionUID = 2598426539166789515L;

However, in a Maven Archetype 11 project., you define an AEM Servlet like this (there is no @SlingServlet annotation):

@Component(service=Servlet.class,

property={

Constants.SERVICE_DESCRIPTION + "=Simple Demo Servlet",

"sling.servlet.methods=" + HttpConstants.METHOD_POST,

"sling.servlet.paths="+ "/bin/myDataSourcePoolServlet"

})

We have a FAQ on setting a whitelist for an OSGi that lets you set a service that uses admin creds. See this blog. Scott's Digital Community: Adobe Experience Manager FAQs and other Tips

there is a whitelist setting under Configurations. See the FAQ. Search whitelist in the blog item.

You need to whitelist the path, bin is already done.

Should be in the logmessages too

Thanks for this article...To resolved the issue above, I change the "/my-demo/servlet" to "bin/my-demo/servlet". But why must we start with "bin" on paths, I continue to research. Thanks all
