Can anyone shed some light on this? I thought POST is allowed and in above is a simple post servlet.

I think what's happening is you have not registered your servlet to accept POST calls, and therefore you're instead hitting the default Sling Post servlet.  Because you're hitting the default Sling Post servlet, it's acting like your POST is a request to save data into the JCR, which is failing and giving you the stack trace indicating a failed commit.

 

To tell AEM that your servlet can accept POST requests, you must add into the `property` config the following:

ServletResolverConstants.SLING_SERVLET_METHODS + "=" + HttpConstants.METHOD_POST,

OR

"sling.servlet.methods=POST"

Hi, 

 

Are you sure that the code you posted here is the same code which is running on AEM? From what I can see, the code should have at least this entry (which I didn't find in your log)


catch (Exception e) {
            log.error("SubscribeServlet error  ", e); //THIS LINE
            throw new ServletException("SubscribeServlet exception");
        }

Also, the log is pointing out this issue, which seems like your servlet is trying to save some changes and does not have permission to do so. However, your code does not have any reference to such operations. Therefore, I guess that you are running a different code. Can you please double-check?

Caused by: javax.jcr.AccessDeniedException: OakAccess0000: Access denied

 

Hope this helps.
