Re: A proposal to change the Apache Chemistry project

Hi Slawas,

to track your proposal, please open an issue here:
https://issues.apache.org/jira/projects/CMIS
I'm a bit reluctant to make this change because I don't know its side-effects. In some environments, OpenCMIS is production for almost 10 years and this may (or may not) break things.
Apart from that, you may consider not using the Web Services binding at all. Although the CMIS specs says that servers should provide all bindings, I can't recommend it because the Web Service binding is much slower and requires much more overhead than the other bindings.

Welcome,



I'm new on the mail list, and sorry if my post seems to be too pert,
but i have some proposal to change in the project. I think that it is
good idea to remove JAXB generation to one package
org.apache.chemistry.opencmis.commons.impl.jaxb.

Why? Because it does not work in my project :)



I'm author of little product (in Poland) called Mercury. This is
server of services to manage any objects some like Elastic Search, but
to serve more businses services. So, three days ago, I came up with
the idea to implement CMIS services. I thought it was nothing
difficult and I started to create a service template. And first day,
after first mock implementation, in test I had error
"java.lang.IllegalArgumentException: Object ID property not set!".
Why? Today I know. In my project I have dependency to MOXy JAXB (I
can't remove it, because other elements had dependency to this).
Summary: in my CMIS services was generated wrong namespace for
'properties':

….

      <ns1:getObjectResponse
xmlns:ns1="http://docs.oasis-open.org/ns/cmis/messaging/200908/";
xmlns:ns0="http://docs.oasis-open.org/ns/cmis/core/200908/";>

         <ns1:object>

            <ns0:properties>

               <ns1:propertyId propertyDefinitionId="cmis:objectId">

                  <ns0:value>testRoot</ns0:value>

               </ns1:propertyId>

....

This is because all objects were generated in one package, and you can
not set multiple namespaces for one package.

I commented in pom.xml of chemistry-opencmis-commons-impl:

                <!--

                <extraarg>-p</extraarg>


<extraarg>org.apache.chemistry.opencmis.commons.impl.jaxb</extraarg>

                -->



All objects are generated in three different packages:

org.oasis_open.docs.ns.cmis.core._200908

org.oasis_open.docs.ns.cmis.messaging._200908

org.oasis_open.docs.ns.cmis.ws._200908



I made the necessary corrections in all project elements indicating
new classes and build all project:

Added new libreres to my project and it works!!!! Now I have response:

….

      <ns1:getObjectResponse
xmlns:ns1="http://docs.oasis-open.org/ns/cmis/messaging/200908/";
xmlns:ns0="http://docs.oasis-open.org/ns/cmis/core/200908/";>

         <ns1:object>

            <ns0:properties>

               <ns0:propertyId propertyDefinitionId="cmis:objectId">

                  <ns0:value>testRoot</ns0:value>

               </ns0:propertyId>

....
So, what do You think about it? I know, maybe I'm only one, but, maybe not. 



Best Regards

Slawas
