Hi Ariel,

thx for telling me about the dispatchProviderInterceptors. I read =
through the DevGuide and some examples and implmented the interceptor =
and a Xjob. Unfortunately so far
I wasn't able to trigger my Job and the provided examples didn't help.=20=


Following I wrote down what I did.=20
Thx for your help so far, I understand if you can't spare the time going =
through it

I startet out with my netbeans project (generate by the OOo-integration) =
which contains, the CentralRegistration.class and my generated starter =
dispatch class=20
called addonStarter.class which handles all my Dispatches and is =
referenced as protocollhandler in the protocolhandler.xcu.=20

I created:=20
- a Interceptor class implementing XDispatchProviderInterceptor and =
XDispatch.
- a job class implementing com.sun.star.task.XJob and implements the =
execute method which shall trigger my interceptor.

I wrote a configuration for my XJob (Jobs.xcu) and saved it along with =
addons.xcu and my protocollHandler.xcu
---------------------------------------
<node oor:name=3D"Jobs">
      <node oor:name=3D"Job _1" oor:op=3D"replace">
          <prop oor:name=3D"Service">
              <value>myaddon.test.InterceptorJob</value>
          </prop>
          <node oor:name=3D"Arguments">
              <prop oor:name=3D"arg_1" oor:type=3D"xs:string" =
oor:op=3D"replace">
                  <value>val_1</value>
              </prop>
          </node>
      </node>
  </node>
 <node oor:name=3D"Events">
    <node oor:name=3D"onFirstVisibleTask" oor:op=3D"fuse">
        <node oor:name=3D"JobList">
            <node oor:name=3D"Job_1" oor:op=3D"replace">
            </node>
        </node>
    </node>
	</node>
</oor:component-data>
---------------------------------------

Then I added my jobs.xcu to my uno-extension-manifest.xml with:

---------------------------------------
<manifest:file-entry =
manifest:media-type=3D"application/vnd.sun.star.configuration-data"
                      =
manifest:full-path=3D"registry/data/org/openoffice/Office/ProtocolHandler.=
xcu"/>
---------------------------------------

This is were I stumble and my Job class wasn't triggered so far. I know =
that my job shall be registered by __getServiceFactory and =
__writeRegistryServiceInfo by
the set implementatiton name: "myaddon.test.InterceptorJob", but I =
couldn't figure out what is necessary that those methods are called by =
openoffice.

I've seen examples where the XJob implementation is set in the jar =
manifest as "RegistrationClassName" and I guess therefor its =
__getServiceFactory is called. In my generated manifest my addonStarter =
class is set as RegistrationClass.

Can you tell me about anything obvious I'm missing to fully register my =
job class?

Thank you!

regards,
Fabian
