Re: [ecf-dev] trouble creating proxy, when my service interface is in a

[David Donohue <dd@xxxxxxxxxxxxxxxx>]

Scott,

Some background:
In integrating ECF into my Equinox OSGi/Eclipse RAP application, I
decided to create a couple extension types like the one you described.

This extension tells an application to listen to register
cftcp://127.0.0.1:3787/server1 as a container.
<extension
         point="org.inqle.ecf.servers">
   		<ecfServer
   			uri="ecftcp://127.0.0.1:3787/server1"
   			port="3787"
   			protocol="ecf.generic.client"/>
</extension>

This extension registers that the app is to produce a service using
the generic container type, for the IHello service:
<extension
         point="org.inqle.ecf.services">
   		<ecfService
   			serviceInterfaceName="org.inqle.qa.common.services.IHello"
   			serviceClassName="org.inqle.qa.common.services.Hello"
   			clientProtocol="ecf.generic.client"
   			serverProtocol="ecf.generic.server"
   			produce="true"
   			consume="false"/>
</extension>
So bundles in my app can easily contribute a specification for which
ECF servers to listen for, using which protocols, and which ECF
services they produce or consume.  To consume a service, any bundle in
my app can do this
Servicer servicer = Servicer.getInstance();
IHello hello1 = servicer.getServiceObject(IHello.class,
"ecftcp://localhost:3787/server1");
log.info("hello1.hello() to hello1 service object returns: " + hello1);

So my setup is a little complex, and that certainly confounds things.
End background.

To answer your questions:

Galileo

I am using what you provided me earlier, 3.1

yes, generic client/server

I have found lots of cases where things don't work :)
My source is here
http://code.google.com/p/inqle/source/browse/#svn/trunk
So when things were not working:
Bundle org.inqle.qa.common had service interface class IHello, and the
implementation class Hello.  [I have since turned off exporting of its
package and placed the interface in the fragment, bundle
org.inqle.qa.services]
Bundle org.inqle.ecf.client has the client and declares the
"ecfServer" extension point.
Bundle org.inqle.ecf.server has the server
Bundle org.inqle.ecf.common has the "ecfService" plugin type.
When I had the above setup, I experienced the error I reported earlier.
When I moved the IHello and Hello classes into bundle
org.inqle.ecf.client (or into a fragment thereof) then it worked.

I hope this helps.  Sorry to dump so much detail on you!
Best,
