RMI Connection to AEM 6.0 via JCR API
Hi,
AEM version: 6.0
Tried to make an rmi connection, from java application.
We followed the steps, as exactly as mentioned on the kb (https://helpx.adobe.com/experience-manager/kb/rmi-connection-crx-cq-561.html) and always we are getting the connection refused exception.
Apart from enabling RMI Connection listener, is we have to do anything at server level for enabling RMI?
In the code, we are referring to a parameter crx-application-name, where we have to configure the same?
Kindly advice us on this.
error.log (After enabling rmi listener):
*INFO* [CM Event Dispatcher (Fire ConfigurationEvent: pid=org.apache.sling.jcr.jackrabbit.server.RmiRegistrationSupport)] org.apache.sling.jcr.registration Using RMI Registry port 1199

Code Snippet:
public static void main (String[] args){
System.out.println("RMI to CRX Test Connection:");
ClientRepositoryFactory factory = new ClientRepositoryFactory();
Repository repository;
String crxApplicationName = "virtual-crx";
String repoUrl = "//localhost:1199/"+crxApplicationName;
String workspace = "crx.default";
String username = "admin";
char [] password = "admin".toCharArray();
try {
repository = factory.getRepository(repoUrl);
Session s = repository.login(new SimpleCredentials(username,password), workspace);
System.out.println("Workspace: " + s.getWorkspace().getName());
System.out.println("userId: "+s.getUserID());
} catch (Exception e) {
e.printStackTrace();
}
}
Exception:

We also tried to make an rmi connection as mentioned on (http://dev.day.com/docs/en/crx/current/developing/accessing_the_crx.html#Accessing a Repository via RMI), in that case also we are getting the same exception

Session session = null;
session = repository.login(creds, "crx.default");

Perhaps the repository you are trying to access is not available at the moment.
