That's right. Chemistry provide all necessary code for : * expose the api in WS or atomPub to client * translate WS or atomPub queries to Java object and service call.
This is when come the services call that we need to implement the lenya repositories call. The first things to implement seems to be the ServiceFactory class, that will provide to CMIS a way to get necessary classes depending on client requirement.
Hope it's clear. ++ On 05/01/2013 04:10 AM, Lsitha Chamara wrote:
Hi Florent, Thanks for the reply. You said that we have to translate chemistry instructions into lenya repository compliant instructions. What I understood is we have to give a client API with apache chemestry as well as a CMIS server implementation which is the client API communicating. Inside that server implementation we are going to call lenya repository. Is that he thing you mentioned ? I am referring to this kind of CMIS server implementation. http://chemistry.apache.org/java/how-to/how-to-create-server.html Regards Lasitha Chamara On Tue, Apr 30, 2013 at 3:33 PM, Florent André <[email protected] <mailto:[email protected]>> wrote: hi, On 04/30/2013 10:51 AM, Lsitha Chamara wrote: Hi, Can we connect to the lenya repository using apache chemestry workbench ? This is the glue you have to develop in order to get chemistry instructions translated into lenya repository compliant instructions. If we run Lenya using built in jetty server what is the location it creates the lenya repository ? by default the repository for each publication is here : lenya/lenya/pubs/$PUBLICATION___NAME/content/ (with embedded jetty you may remove the first "lenya" folder) You can define another location for each publication by modifying the file : $MYPUB_HOME/config/__publication.xml with <content-dir src="/home/john/src/lenya/__data/content"/> change src for any folder you want.

Even if the actual one have no clear interface, it's work and this development will give you good ideas on limits and good points of this implementation. In a second step, you can then start designing a new repository api and implementation that can be plug behind chemistry. == About Spring From my point of view, Spring technologies is between IOC actually provided by avalon/excalibur [1] actually used in Lenya and OSGI technologies that are recent, powerfull and in the target for the future of Lenya. Still for me, I find Spring big, really verbose and no so maintainable (I don't have big spring experience though). Apart from that, Lenya already have an authentication / authorization mechanism that is pretty simple and configurable via the user interface or files. In order to have a good integration of the CMIS with Lenya I think we have to rely on that. Regards.

I thought of implementing this using spring restful services (Spring controllers) so that repository handling operations will be centralized. Ans as for the authentication mechanism I though of using a URL based authentication mechanism (Define a dispatcher servlet and a fliter for authenticate users to perform the repository operations ) .I went through spring security framework and they have done it. It would be nice if you can comment your idea on this.

I will try to finish the maven migration before the summer, but really not sure to achieve this goal in the timeline... So, to be clear, don't think about this migration for now, it's on my side, stay focused on the CMIS and repository definition ! :) Have you already writing down your proposal ?
