Ah ha, that's right, I forgot you will need to create a custom file node type
instead of resource. In our env, I've created custom node types for folder,
file and resource to allow any custom properties we want. I just happened to
have the code right in front of me....
----
//if not already registered you'll have to register the namespace
//
ses.getWorkspace().getNamespaceRegistry().registerNamespace("company","http:/
/company.com/jr/ns/1.0");
public void register(Session ses) throws Exception {
registerNodeType(ses,"company:folder","nt:file",false);
registerNodeType(ses,"company:file","nt:file",false);
registerNodeType(ses,"company:resource","nt:resource",true);
}
public void registerNodeType(Session ses, String name, String superType,
boolean versionable) throws Exception {
NodeTypeManager ntm = ses.getWorkspace().getNodeTypeManager();
if(ntm.hasNodeType(name)){
ntm.unregisterNodeType(name);
}
NodeTypeTemplate ntt = createNodeType(ses,name, superType,versionable);
ntm.registerNodeType(ntt,true);
ses.save();
}
public NodeTypeTemplate createNodeType(Session ses, String name, String
superType, boolean versionable) throws Exception{
NodeTypeManager ntm = ses.getWorkspace().getNodeTypeManager();
PropertyDefinitionTemplate pdts = ntm.createPropertyDefinitionTemplate();
pdts.setName("*");
pdts.setMultiple(false);
PropertyDefinitionTemplate pdtm = ntm.createPropertyDefinitionTemplate();
pdtm.setName("*");
pdtm.setMultiple(true);
NodeTypeTemplate ntt = ntm.createNodeTypeTemplate();
ntt.setName(name);
ntt.getPropertyDefinitionTemplates().add(pdts);
ntt.getPropertyDefinitionTemplates().add(pdtm);
if(versionable){
ntt.setDeclaredSuperTypeNames(new String[] {superType,
JcrConstants.MIX_VERSIONABLE});
}else{
ntt.setDeclaredSuperTypeNames(new String[] {superType});
}
return ntt;
}

One other note. From your initial question it sounded like you register every
time create a new session? It should be a onetime thing, then the node types
will just be available to new sessions.

Subject: Re: How to add unversioned metadata to a versioned node?
Hi Mark,
Thanks for the reply. What you say makes sense, but I'm having a hard time
figuring out how to do it. I mean, I can see by looking at my code why it's
doing what it's doing. But I'm not quite able to wrap my head around some of
these node-type concepts enough to change it to what I want.
If you have a moment, could you look at this piece of code and tell me if you
have any quick pointers? Maybe some quick pseudo-code?
In addition to the code I provided previously, here's a sample of what I
currently have for creating a node for a new file....
-----------------------------------------------------------------------------
-----------------------------------------------------------
Node folderNode = session.getNode(folderPath); Node fileNode =
folderNode.addNode(fileName, "nt:file");
fileNode.addMixin("mix:versionable");
Node resNode = fileNode.addNode("jcr:content", "fileContent");
resNode.setProperty("jcr:mimeType", mimeType);
resNode.setProperty("jcr:data", stream);
resNode.setProperty("jcr:lastModified", Calendar.getInstance());
resNode.setProperty("description", description); session.save();
vman.checkin(fileNode.getPath());
-----------------------------------------------------------------------------
-------------------------------------------------------
It seems to me that I should (conceptually) change the code from above to
something like the following....
However, I can't figure out to add custom properties to that top-level node.
-----------------------------------------------------------------------------
-----------------------------------------------------------
Node folderNode = session.getNode(folderPath); Node fileNode =
folderNode.addNode(fileName, "nt:file"); fileNode.setProperty("description",
description); Node contentNode = fileNode.addNode("jcr:content",
"fileContent"); contentNode.addMixin("mix:versionable");
contentNode.setProperty("jcr:mimeType", mimeType);
contentNode.setProperty("jcr:data", stream);
contentNode.setProperty("jcr:lastModified", Calendar.getInstance());
session.save(); vman.checkin( contentNode.getPath());
-----------------------------------------------------------------------------
-------------------------------------------------------
