Creating links

Hello everyone,
I wanted to know whether code, through WebService, I can insert a Item (any binary document) and then create always code a link to this file in other folders without replicate the file again.
Thank you.

Rocco.

Hi,

here is a method to create a link of a node in another destination,

It assumes you have the object you want to link and the destination as Alfresco Node Type …

public boolean addLink(Node object, Node destination)
&nbsp;&nbsp;&nbsp;{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;boolean result = false;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;try
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ParentReference to = new ParentReference(
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Constant.STORE,
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;destination.getReference().getUuid(),
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;destination.getReference().getPath(),
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Constants.ASSOC_CONTAINS,
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Constants.ASSOC_CONTAINS);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Predicate where = new Predicate( new Reference[] { object.getReference() }, null, null );

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CMLAddChild addChild = new CMLAddChild();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;addChild.setTo(to);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;addChild.setWhere(where);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CML cml = new CML();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;cml.setAddChild(new CMLAddChild[] {addChild});

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;UpdateResult[] updateResult = repositoryService.update(cml);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;result = (updateResult != null);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;catch(RepositoryFault e)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;System.out.println("RepositoryFault: " + e.getMessage() + "\n" + e.getStackTrace());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;catch(RemoteException e)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;System.out.println("RemoteException: " + e.getMessage());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return result;
&nbsp;&nbsp;&nbsp;}

Hope it helps

Hello,
I wanted to ask how you can create the node destination,
The crux origin so recovery through a search XPATH and the step to your method, but I would not know how to create the node destination.
The manufacturer requires the parameters that I do not know what they are.
For example this is the code that I use but I do not know whether it is right to create the Reference as I have done and also do not know how to create the node dest to send then the method that I have recommended.

Reference reference = new Reference(STORE, null, "/app:company_home/cm:categoria/cm:links");
Node dest=new Node(reference,"prova",null,null);
addLink(sourse,dest);

Thank you.

Hello everyone,
I did the tests and it was solving the problem I had initially with knots.
Now I have another problem. If a link gate of what I created him I erase all that can be found in other folders plus links to real, in practice a link gate and I delete everything.
how can I do to him only delete the link that refers to the object in the repository and not everything?
Thank you.
