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

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.

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

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

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 🙂

That means that a file has been uploaded on a node and if you have a node, below method is use to get nodeRef of that node.
NodeRef nodeRef = JCRNodeRef.getNodeRef(Node);

but i don't know where to get my node.. :cry:

what im trying to do is to write a query using lucene, then try to get its nodeRef, but i can't seem to make it work.
i uploaded the file inside the company home (app:company_home), and my file's name is generated by timestamp :

String name = "RequestMembership (" + System.currentTimeMillis() + ")";
RequestImage.setChildName("cm:" + name);

i have seen an example on how to query then get its nodeRef after, but i dont know how i can put in here:

ResultSet resultSet = searchService.query(storeRef, SearchService.LANGUAGE_LUCENE, "HERE"");
NodeRef companyHome = resultSet.getNodeRef(0);

the path plus the name of my image..

:cry:

You could use a combination of PATH query and property query:


ResultSet resultSet = searchService.query(storeRef, SearchService.LANGUAGE_LUCENE, "+PATH:\"/app:company_home/*\" +@cm\\:name:\"RequestMembership*\"");
NodeRef companyHome = resultSet.getNodeRef(0);

This wiki lucene search page might help you further with a lot of examples at http://wiki.alfresco.com/wiki/Search

thanks amit!

i used webscripts and js to search using lucene

i did this and it worked:

var docs = search.luceneSearch(" @cm\\:name:\""+args.filename+"\"");
   var log = "";

    for (var i=0; i<docs.length; i++)
            {
                   log += "NodeRef: " + docs.nodeRef + "\r\n";
             }

         logFile.content = log;

i called the webscripts in adobe flex via httpservice and passed the name of my file to the webscripts, and it works perfectly for calling my workflow
