try with User class, if it helps

 

import org.apache.jackrabbit.api.security.user.User;

 

User currentUser = request.getResourceResolver().adaptTo(User.class);

This is very simple servlet and just to test I was trying to understand issue with adaptTo here -

 

package com.aem.demo.core.servlets;

import java.io.IOException;

import javax.jcr.RepositoryException;
import javax.servlet.Servlet;

import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.servlets.HttpConstants;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Component;

import com.adobe.granite.security.user.UserProperties;

@component(service = Servlet.class, property = { "sling.servlet.paths=" + "/bin/username",
"sling.servlet.methods=" + HttpConstants.METHOD_GET })
public class UserPropertiesServlet extends SlingAllMethodsServlet {




/**
*
*/
private static final long serialVersionUID = -3561858749807565841L;

protected void doGet(SlingHttpServletRequest slingHttpServletRequest, SlingHttpServletResponse slingHttpServletResponse) {

ResourceResolver resourceResolver = slingHttpServletRequest.getResourceResolver();

UserProperties userProperties = resourceResolver.adaptTo(UserProperties.class);
try {
slingHttpServletResponse.getWriter().write(userProperties.getDisplayName());
} catch (IOException | RepositoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

 

But I didn't face such problem and here is the servlet response -

Could you please tell me what are you trying to achieve via the servlet or code overview.

the error does NOT happen all the time.

 

I'm trying to read user properties.

Are you facing this intermittent issue on publish instance? how are you accessing it?
