Handle file name duplication when creating files in alfresco - alfresco

Question

I have a Java-backed webscript in repo tier that creates files (with given name) in a given folder in Alfresco.
To handle the file name duplication issue I wrote this code:
NodeRef node = null;
try {
node = createNode(fullName, folderNodeRefId);
} catch (DuplicateChildNodeNameException e) {
System.out.println("Catched");
boolean done = false;
for (int i = 1; !done; i++) {
String newName = filename + "_" + i + "." + fileFormat;
System.out.println("Duplicate Name. Trying: " + newName);
try {
node = createNode(newName, folderNodeRefId);
done = true;
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
System.out.println("Done");
ContentWriter writer = serviceRegistry.getContentService().getWriter(node, ContentModel.PROP_CONTENT, true);
writer.setMimetype(getFileFormatMimetype(fileFormat));
writer.putContent(inputStream);
writer.guessEncoding();
and
private NodeRef createNode(String filename, String folderNodeRefId)
throws InvalidNodeRefException, InvalidTypeException, InvalidQNameException {
System.out.println("In " + filename);
NodeRef folderNodeRef = new NodeRef(folderNodeRefId);
Map<QName, Serializable> props = new HashMap<QName, Serializable>(1);
props.put(ContentModel.PROP_NAME, filename);
return serviceRegistry.getNodeService()
.createNode(folderNodeRef, ContentModel.ASSOC_CONTAINS,
QName.createQName(NamespaceService.CONTENT_MODEL_1_0_URI, filename), ContentModel.TYPE_CONTENT,
props)
.getChildRef();
}
The codes work very fine if there is no file name duplication (a new name). But it does nothing when there is a duplication, although it executes without any errors! When I test it it doesn't throw any exceptions but no file is created either!
Any hints about the cause of that?
Thanks,

I tested this code , It's working fine
#Test
public void createNode() {
AuthenticationUtil.setFullyAuthenticatedUser(ADMIN_USER_NAME);
NodeRef node = null;
String fileFormat = "txt";
String filename = "test";
NodeRef folderNodeRef = getCompanyHome();
//Create first node
node = createNode(filename, folderNodeRef);
try {
node = createNode(filename, folderNodeRef);
} catch (DuplicateChildNodeNameException e) {
System.out.println("Catched");
boolean done = false;
for (int i = 1; !done; i++) {
String newName = filename + "_" + i + "." + fileFormat;
System.out.println("Duplicate Name. Trying: " + newName);
try {
node = createNode(newName, folderNodeRef);
done = true;
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
System.out.println("Done");
}
private NodeRef getCompanyHome() {
return nodeLocatorService.getNode("companyhome", null, null);
}
private NodeRef createNode(String filename, NodeRef folderNodeRef) throws InvalidNodeRefException, InvalidTypeException, InvalidQNameException {
System.out.println("In " + filename);
Map<QName, Serializable> props = new HashMap<QName, Serializable>(1);
props.put(ContentModel.PROP_NAME, filename);
return serviceRegistry.getNodeService().createNode(folderNodeRef, ContentModel.ASSOC_CONTAINS,
QName.createQName(NamespaceService.CONTENT_MODEL_1_0_URI, filename), ContentModel.TYPE_CONTENT,props).getChildRef();
}
