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() + "=");
if (property.getDefinition().isMultiple()) {
Value[] values = property.getValues();
for (int i = 0; i < values.length; i++) {
if (i > 0)
System.out.println(",");
System.out.println(values[i].getString());
}
} else {
if (property.getType() != PropertyType.BINARY)
System.out.print(property.getString());
else if (expandBin)
System.out.print(property.getString());
else
System.out.print("["+property.getLength()+"] Data Not Printed!");
}
System.out.println();
}
NodeIterator nodes = node.getNodes();
while (nodes.hasNext()) {
Node child = nodes.nextNode();
dump(child, expandBin);
}
}

Subject: Re: what does NodeTypeRegistry.reregisterNodeType() do?
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 -- 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.

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.
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.
