what does NodeTypeRegistry.reregisterNodeType() do?

[Betty Chang-3]

Hi -

I've been able to add custom node types within the jackrabbit server app.

However, is it possible to add new properties to a node type that is already registered?

I first call isRegistered() to see if a nodeTypeName is registered, and if it is, I call
reregisterNodeType() in the hopes that it would re-register the node type with the new properties I have
added.

However, new properties do not seem to get registered.

What does reregisterNodeType() actually do?

you can only register 'trivial' node type changes, i.e. changes that
do not affect existing content.

a trivial change would e.g. be adding a non-mandatory property.

a non-trivial (and thus non-supported change) would e.g. be adding a
mandatory property
or adding a value constraint to an existing property definition.

what exactly are you trying to change?

reregisterNodeType() allows to modify the definition of
an existing, already registered node type. only trivial
changes are currently supported.

for more details see:
http://jackrabbit.apache.org/api-1/org/apache/jackrabbit/core/nodetype/NodeTypeDefDiff.html

Hi --

I was trying to just add another string property, and I did not specify
"mandatory" in my .cnd file, so does that mean it is
non-mandatory?

I did a dump after the re-register, but the new property does not show up
under  /jcr:system/jcr:nodeTypes anywhere, and
I cannot seem to set it when I add my node.

Thanks

Betty

Hi -- Did you wish to see sample code on the server side where I do the
re-register, or on the
client side where I read the stuff?

Hi

I have node type with following structure.
book:file  and book:folder  extends book:node.

When I make an node as node:file , is it possible to make property of
book:node non- versionable and property of book:file as versionable.
Basically user can change name, path title ...without making versions but
when book:content is changed, node should be versioned.



[book:node] > nt:base
- book:name (string) mandatory
- book:path (string)  
- book:title (string)
- book:nodeType (string)
- book:description (string)
- book:reportID (string)
- book:createdDate (date)
- book:publishedDate (date)
- book:unPublishedDate (date)
- book:region (string)
- book:department (string)
- book:language (string)
- book:organizationID (string)
- book:keywords (string)
- book:securityRoles (string)multiple

[book:file] >  book:node
- book:content (binary)  
- book:contentTxt (string)


[book:folder] >  book:node
+ * = book:file multiple

Thanks

both if possible.

BTW: what protocol are you using for remotely accessing the repository?

Hi --

I got side-tracked a bit, but I will try to put together a code snippet.

In answer to the protocol question,  the remote client uses the spi webdav
interface

ah, i see. that explains it. this is probably a caching issue of the spi layer.
please feel free to create a jira issue. you can attach your sample code to
that issue.

the SPI layer does not support nodetype registration
anyway, since this a jackrabbit specific extension
and not part of the JCR API.
how did you register the nodetype?

> please feel free to create a jira issue.

before you create an issue, i'd like to understand
how you registered the nodetype.

[Betty Chang-3]

Hi -- I'm doing the nodetype registration on the server side as a servlet.
Originally,
I did it in a separate webapp in the same tomcat server
as the jackrabbit server, then I changed it to a servlet within the
jackrabbit webapp.
I configured the servlet to load on startup after all other startup
servlets.  It reads in the .CND file, checks if a nodetype
already exists, and if so, it re-registers it.  If not, it just registers
it.

My client programs are able to add to the repository using these custom node
types and they show up under
jcr:system/jcr:nodeTypes in the tree.

I can add a new node type to the CND file, restart the tomcat, and the new
node type shows up in the dump on
the client side.
However, if I add a new property to an existing node type, the new property
does not show up.

I'm not sure why it would be a caching issue, because my client program is
just a little test program that can dump out all
the nodes and I run it fresh everytime.

Hi -- I've attached a couple of pieces of code.  The servlet is the code
that registers or re-registers the node types.  I run it
in the same webapp as jackrabbit, and have it load on startup after
everything else.
The dumpsnippet.java is from a test program that just dumps the nodes.   I
call it at the "/jcr.system/jcr.nodeTypes" level
  to see all the node types and their properties.   This is run via the spi
webdav interface.

I can add node types to the CND file and restart tomcat and all is well, but
adding non-mandatory properties to an
exisiting node type does not seem to do anything.

Thanks

Betty

Hi --  my attachments did not  appear.  Let me try that again with just code
inserted.

Here's the servlet code that registers or re-registers node types:

===========================================

public class NodeTypeConfigServlet extends HttpServlet{

 /**
  * default logger
  */
 private static final Logger log =
LoggerFactory.getLogger(NodeTypeConfigServlet.class);

 static final String NODETYPE_CND_FILE_NAME="edgeNodeTypes.cnd";
 static final String EDGE_NAMESPACE_URI="http://www.edgenuity.com/edge";
 static final String EDGE_PREFIX="edge";
 static final String SUPERUSER_USER="admin";
 static final String SUPERUSER_PW ="admin";

 private Repository repository = null;

 public void init() throws ServletException {
  super.init();
  CompactNodeTypeDefReader cndReader;

  try {
   //repository = rf.getRepository();
   repository = new ServletRepository(this);

   char[] pwarr = SUPERUSER_PW.toCharArray();
   SimpleCredentials sc = new SimpleCredentials(SUPERUSER_USER,pwarr);
   Session session = repository.login(sc, null);
   Workspace ws = session.getWorkspace();
   NamespaceRegistry nsReg = ws.getNamespaceRegistry();
   try {
    String uri = nsReg.getURI(EDGE_PREFIX);
    log.info("Prefix "+EDGE_PREFIX+" has already been registered under URI
of "+uri);

   } catch(NamespaceException nex) {
    // prefix is not mapped, so register it
    nsReg.registerNamespace(EDGE_PREFIX, EDGE_NAMESPACE_URI);
   }

   // Read in the CND file
   InputStreamReader rd = new
InputStreamReader(this.getClass().getClassLoader().getResourceAsStream(NODETYPE_CND_FILE_NAME));
   //
   // Create a CompactNodeTypeDefReader
   cndReader = new CompactNodeTypeDefReader(rd, NODETYPE_CND_FILE_NAME);

   // Get the List of NodeTypeDef objects
   List ntdList = cndReader.getNodeTypeDefs();

   // Get the NodeTypeManager from the Workspace.
   // Note that it must be cast from the generic JCR NodeTypeManager to the
   // Jackrabbit-specific implementation.
   NodeTypeManagerImpl ntmgr =(NodeTypeManagerImpl)ws.getNodeTypeManager();

   // Acquire the NodeTypeRegistry
   NodeTypeRegistry ntreg = ntmgr.getNodeTypeRegistry();


   // Loop through the prepared NodeTypeDefs
   for (Iterator i = ntdList.iterator(); i.hasNext();) {

    // Get the NodeTypeDef...
    NodeTypeDef ntd = (NodeTypeDef)i.next();

    log.info("----NODE TYPE DEF node name="+ntd.getName());
    // register it if it is not already registered
    if (ntreg.isRegistered(ntd.getName())) {
      log.info("Node type "+ntd.getName()+ " is already registered -- it
will be re-registered in case properties have been changed");
    }

    else {
     log.info("Node type "+ntd.getName()+" wil be registered ");
     ntreg.registerNodeType(ntd);
    }
   }

  }
  catch (NamespaceException nex) {
   throw new ServletException(nex);
  }
  catch (RepositoryException ex) {
   throw new ServletException(ex);
  }
  catch (org.apache.jackrabbit.core.nodetype.compact.ParseException pex) {
   throw new ServletException(pex);
  }
  catch (org.apache.jackrabbit.core.nodetype.InvalidNodeTypeDefException
iex) {
   throw new ServletException(iex);
  }
 }
}

======================================================
and here's the snippet that dumps out nodes on the client side via the spi
webdav interface:

private void dump(Node node, boolean expandBin) throws RepositoryException
  {
    System.out.println("NODE = "+node.getPath());
    PropertyIterator properties = node.getProperties();
    Property property = null;
    while (properties.hasNext()) {
 property = properties.nextProperty();
 System.out.print("----Property "+property.getPath() + "=");
