Hi,

I am using CQ5.6. I am using admin resolver to get session. I create nodes and then save the session using session.save(). I am creating multiple nodes in a loop. However each time when I run the code, I get session exception and code execution stops without creating all the nodes. Is it because of this admin resolver that my execution stops in between? What can be the solution?

Make sure you close() the session in a finally{} block, I don't see the close in your code.

Hi,

looks like you are using a session with multiple threads. Don't do this, as it will cause all kind of weird problems.

Please post the code so communuty can see what is happening. Also, are you using Sling Mapping service to map system user to get a session?

Hi,

PFB code snippet:

ResourceResolver adminResolver = resolverFactory.getAdministrativeResourceResolver(null);

Session session = adminResolver.adaptTo(Session.class)

Node node= JcrUtils.getOrCreateByPath(livePath, DamConstants.NT_SLING_ORDEREDFOLDER, session);

for(Group group : groupDetail.getGroups()){
                       String nodeName = StringSimplifier.simplifiedString(group .getGroupName());
                       Node roleNode = dataScopesecurityRoleNode.addNode(dataNodeName );
                       roleNode .setProperty("dataRole", group.getGroupName());

                       session.save();

                       for(GroupIDs group1 : group.getGroupIDs()){


                           Node childNode = roleNode .addNode(group1.getName(), "nt:unstructured");


                           childNode.setProperty("role", group1.getGroupName());
                           childNode.setProperty("id", group1.getGroupID());
                           session.save();
                       }

                   }
                   session.save();
               }
