    How to add a document to the JCR Repository via Java API

    u005078 Level 1

      I'm trying to get started with the JCR 2.0 " Content Repository Java Technology API Specification" It's really a great document but I miss a minimum of examples to visualize how it is all fits together.

      For a start I want to add a pdf-document to my local CRX repository. Form the book I see, that I must add a Node and add the Properties.

       

      File file = new File("/mypath/mydocument.pdf"); 
      FileInputStream is = new FileInputStream(file); 
      ValueFactory valueFactory = session.getValueFactory(); 
      Binary myBinary = valFact.createBinary(is); 
      Value valueFactory =valFact.createValue(myBinary);
      Node nodeCarl=content.addNode("Carl", "nt:file");
      Property pCarl=nodeCarl.setProperty("jcr:data", myBinary); 
      
      
      

      The program fails with:

      javax.jcr.nodetype.ConstraintViolationException: no matching property definition found for {http://www.jcp.org/jcr/1.0}data in the lastt cited line.

      I don't know, why this comes up with ..jcr/1.0; The Classpath consists of JCR-2.0.jar and jackrabbit-standalone-2.2.13.jar.

       

      Any hint to get this stored is appreciated.

          The reason you are getting a ConstraintViolationException is because you are creating a node of type nt:file. The nt:file node as per the JCR specification[0], requires a child node jcr:content which contains the actual file contents.

          Here is an updated snippet of Java code I created to store a PDF file into CRX:

           

          File file = new File("/mypath/mydocument.pdf");   
          FileInputStream is = new FileInputStream(file); 
          Node node = _session.getNode(parentNode);  
          ValueFactory valueFactory = session.getValueFactory();             
          Binary contentValue = valueFactory.createBinary(is);            
          Node fileNode = node.addNode(fileName, "nt:file"); 
          fileNode.addMixin("mix:referenceable"); 
          Node resNode = fileNode.addNode("jcr:content", "nt:resource"); 
          resNode.setProperty("jcr:mimeType", mimeType); 
          resNode.setProperty("jcr:data", contentValue); 
          Calendar lastModified = Calendar.getInstance(); 
          lastModified.setTimeInMillis(lastModified.getTimeInMillis()); 
          resNode.setProperty("jcr:lastModified", lastModified); 
          session.save();            
          
          
          // Return the path to the document that was stored in CRX. 
          return fileNode.getPath();
          

           

           

          Hope this helps
