How to restart the repository session

ethan — Mon, 13 Sep 2010 12:12:21 GMT

Hi I'm trying to add some nodes to the Alfresco Repository. I iterate through a tree and copy each nodes and their children into the Alfresco repository. Sometimes, an exception is thrown (like DuplicateChildNameException). I used a try catch for each node and I would like that when an exception i

Unfortunately you can't catch the exception and carry on since the current transaction is rolling back.

If it is a big long list of nodes then do you need to process them all as one transaction or could you process them in individual transactions?

If you do need a big long list then you need to do as much validation up front as possible.

Currently, I save each node at a time. I use the following code :

try {
   String nodeRelPath = ISO9075.encode(nodeName);
         
   if(!alfParentNode.hasNode(nodeRelPath)){ 
      try{
         Node newAlfNode = alfParentNode.addNode(nodeRelPath, customNodeType);
         newAlfNode.setProperty("cm:name", "myNodeName");
         …
         sessionALF.save();
         convertChildrenNodes(sessionALF, childNode, newAlfNode);
               
      } catch(RepositoryException e){
         System.out.println("ERROR WHILE SAVING NODE :" + nodeName + " - " + e.getCause());
      }
                     
   } else { 
      Node newAlfParentNode = alfParentNode.getNode(nodeRelPath);
      System.out.println("already existing node : " + nodeName);
      convertChildrenNodes(sessionALF, childNode, newAlfParentNode);
   }

} catch (RepositoryException e) {
   e.printStackTrace();
}

Up !

Is this the right way to proceed or is there a better one ?

Thank you

Should I use explicit transactions like it is defined here in the wiki ? If I use the trx.rollback() in the catch() part, will I still be able to use the session and get back to the parent node to continue to iterate?
