Hi,

I was trying to access jcr repository of QA instance from the dev instance using a sling servlet. But i am facing an exception as mentioned below:

 

Please help me out with this. And also let me know if this scenario is possible or not.

 

Sling Servlet code:

package com.demo.core.servlets;

import com.google.gson.JsonArray;
import com.google.gson.JsonObject;
import com.demo.core.utils.Entity;
import com.demo.core.utils.EntityUtil;
import com.demo.core.utils.impl.EntityUtilImpl;
import org.apache.jackrabbit.commons.JcrUtils;
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.SlingAllMethodsServlet;
import org.apache.sling.jcr.api.SlingRepository;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;

import javax.jcr.*;
import javax.servlet.Servlet;
import java.io.IOException;
import java.io.PrintWriter;

@Component(service = Servlet.class, property = {"sling.servlet.methods=" + "GET",
"sling.servlet.paths=" + "/bin/validate"})
public class DataValidation extends SlingAllMethodsServlet {
/**
*
*/
private static final long serialVersionUID = 1L;

@Reference
SlingRepository slingRepository;


@Override
protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response)
throws IOException {
//get request param
String parentPath = request.getParameter("parentPath");
String uri = request.getParameter("uri");
String origin = request.getParameter("origin");
ResourceResolver resourceResolver = null;
Session jcrSession = null;
if (uri.isEmpty() && !parentPath.isEmpty()) {
//resource resolver created from request
resourceResolver = request.getResourceResolver();
jcrSession = resourceResolver.adaptTo(Session.class);
} else if(!uri.isEmpty() && !parentPath.isEmpty()) {
try {
Repository repository = JcrUtils.getRepository(uri+"/crx/server");
jcrSession = repository.login(new SimpleCredentials("admin","admin".toCharArray()));
Node rootNode =jcrSession.getRootNode();
} catch (RepositoryException e) {
e.printStackTrace();
}
}else{
//return response that uri and path is not available
}

}


}

}

 

Exception Occurs:

javax.jcr.RepositoryException: Unable to access a repository with the following settings:
org.apache.jackrabbit.repository.uri: http://{server-ip:port}/crx/server
The following RepositoryFactory classes were consulted:
Perhaps the repository you are trying to access is not available at the moment.
