Hi --
Hmm, I don't know if I explained my problem well enough.
Yes, we are running jcr2spi running on the spi2dav implementation
yes, I register/reregister nodetypes on the server side
Now comes the more confusing part of my explanation.
On the client side, I use use session.getRootNode() and proceed to dump out
the tree to see what is there.
All the nodetypes that I first register show up.
I can stop the tomcat, add some new nodetypes to the CND file, run the
server again to register/reregister nodetypes, and
the new node types will show up on the client side if I run a fresh program
to dump out the tree. Also, I can use the new nodetypes when I add new
content.
However, if I try to add new properties to existing node types in the CND
file, the reregistration does not seem to do anything
because the new properties never show up when I dump the tree. If I try to
add new content using those new properties, the
program will complain because it does not think those properties exist.
Did that make any sense?

hi betty
sorry for the delay.
let me summarize your findings to see if i properly
understood the problem. you have
- jcr2spi running on the spi2dav implementation.
- you register/reregister nodetypes directly on the server side.
- the content-representation of your nodetypes under
/jcr:system/jcr:nodeTypes shows your custom definitions.
- however, the nodetypes exposed through the NodeTypeManager
accessed through session.getWorkspace().getNodeTypeManager() don't
reflect the changes.
is that correct?
if it is i would assume that it is caused by the following
behaviour:
- jcr2spi reads nodetype definitions through the SPI only.
- jcr2spi currently has no possibility to detect changes
made to nodetypes.
- new nodetype definitions will be detected (loaded from the
server) if the nodetype is accessed directly or indirectly.
if my assumption is correct, your reregistered definitions
will only show up, if you create a new client repository.
could you confirm this?
without having thought about it carefully, i's say there are
two possibilities in order to make jcr2spi aware of changes
made to nodetype definitions:
- implement extended JSR 283 nodetype functionality and
mandate that the nodetypes are managed through the JCR
API only.
- add some sort of observation mechanism to detect modifications
to the set of registered nodetypes, e.g. by having an
event listener to /jcr:system/jcr:nodeTypes tree.
however, this would not be garanteed to work, since nodetype
registration is not part of JSR 170 and observation is
an optional feature.
currently i would prefer the first variant.
kind regards

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.
