    Remove all children of a node [modeshape]

    Nayyereh Fazileh Newbie

      Hi,

      I have node with some properties and a child node that is [nt:folder] type and there are some [nt:file] node type into that. Now I want to remove this node with all sub tree (prpperties and childs) .

      I tried this command:

       

      node.remove();

      But the node just removed and files child in reporsitory remain yet.

       

      I tried these code:

       

      JcrTools tools = new JcrTools();

      tools.removeAllChildren(node);

      PropertyIterator pIt = node.getProperties();

                  while (pIt.hasNext()) {

                      javax.jcr.Property property = pIt.nextProperty();

                      if (!property.isNode()) {

                          System.out.println("pname: " + property.getName());           // just for test

                          property.remove();

                      } else {

                          property.getNode().remove();

                      }

                  }

      node.remove();

       

      But throws:

      java.io.FileNotFoundException: home/user/Repository/83 (Is a directory) ...

       

      If my way is not correct , I will be appreciate if you help me.

      Thank you.

          node.remove() should remove the node and its entire subgraph. However, you need to call session.save() to make sure the changes are persisted (even if you use JcrTools, you still need to call session.save afterwards)

            Thanks for your answer, but I used session.save() after these codes but files childs remain yet!

              Ok, in this case please attach your configuration and if possible the node types involved in this scenario. Did you check the logs/output for any errors/warnings during the remove operation ?

               

              Are you using federation by any chance ? The only cases I can think of when a  java.io.FileNotFoundException would be raised in relation to removing a node would either be a) you're using an ISPN file store and something is corrupted on the disk or b)  you're using federation and the FS connector.

                  Thanks for data, your configuration looks ok (the transactionManagerLookup attribute is deprecated, but doesn't influence anything).

                   

                  I should've asked the first time: are you using the 3.2.0 version of Modeshape ? (I noticed the ISPN xsd is 5.1, while 3.2.0 uses Infinispan 5.2.5)

                   

                  Also, can you please attach the server log so I can see the full stacktrace of the exception ?

                    I am using ModeShpae 3.1.1 version.

                    and this is server log:

                      Please try using ModeShape 3.2.0 and check if this is still happenning. Not only have we fixed 120 issues from 3.1.1 to 3.2.0, but the change in Infinispan from 5.1.x to 5.2.x is significant.

                       

                      Thanks

                        I will use Modeshape 3.2.0 and test it.

                        Thank you for considering my problem.
