How to get NodeRef of an already uploaded file?

[amit_wmw]

Hello,

I am having a content file (say Amit.txt) in company Home. And assuming that I have a custom method by name checkOut(String A), where parameter “String A” is Amit.txt that will be send by any invoking class. Now can you please suggest me how to get NodeRef for Amit.txt? Below is the full code scenario where I want to use this(basically its to checkout Amit.txt in company home itself).

#####################################################################

public void checkOut(String A){
      //this.fileRef=fileRef;
      
          try{
         
         ApplicationContext context = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
         Repository repository = (Repository)context.getBean("JCR.Repository");
         Session session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()));
         
         NodeRef NR= ????????????????????
         
         
         ChildAssociationRef Parent=nodeSevice.getPrimaryParent(NR);
                  
         FileInfo fileinfo = fileFolderService.getFileInfo(NR);

         fileRef = fileinfo.getNodeRef();

         CheckOutCheckInService checkOutCheckInService= serviceRegistry.getCheckOutCheckInService();

         checkOutCheckInService.checkout(fileRef, Parent.getParentRef(), ContentModel.ASSOC_CONTAINS, ContentModel.TYPE_CONTAINER);
         
         
         session.save();
         }
         catch (Exception exp ){
         System.out.println (" error while creating nodes " + exp);
         exp.printStackTrace();
         }
         
         }

To get the NodeRef with JCR is described in the wiki at:

Lothar, thanks for the quick reply!

But the link you suggested above speaks all about Node and not NodeRef and for my code scenario I need NodeRef, because I am making use of checkout method of checkOutCheckInService class, which requires NodeRef.

Please suggest.

Thanks
Amit

The example code of the section shows how to convert the JCR node to an Alfresco NodeRef by the use of the helper class JCRNodeRef:

// convert the JCR Node to an Alfresco Node Reference
NodeRef nodeRef = JCRNodeRef.getNodeRef(jcrNode);
‍‍‍‍

The JCR Node has to be obtained first using one of the JCR lookup methods.

Thanks dear!

Similarly ,do you know any way to get Node out of a NodeRef? If please share. Will be kind.

kind regards-
Amit.

A direct lookup by id might work for the other way round:

Node jcrNode = session.getNodeByUUID(nodeRef.getId());‍

Hi!

im really new at this, where do you invoke these codes? to get the noderef?
sorry if you think this question is silly, but i really dont know where…  :roll:

Hi Pamela,

You have to explore your question a bit more. Do you mean to say where we are writing and executing this codes? Or you want to know anything in particular about Noderef?

And remember silly mistakes leads to big problems, similarly correcting silly mistakes lead people to great success 🙂
