Hi folks,
I'm trying to use remote services over ECF with the XMPP provider. In
order to register and retriever remote services I need to get the
IRemoteServiceContainerAdapter:
IPresenceContainerAdapter adapter = (IPresenceContainerAdapter)
this.container
.getAdapter(IPresenceContainerAdapter.class);
I'm running in a NPE. Debugging the ECF-Code I found out that
the XMPPContainer returns null
providing org.eclipse.ecf.remoteservice.IRemoteServiceContainerAdapter as clazz
parameter.
public Object getAdapter(Class clazz) {
if (clazz.equals(IPresenceContainerAdapter.class))
return this;
if (clazz.equals(ISendFileTransferContainerAdapter.class))
return outgoingFileTransferContainerAdapter;
else
return super.getAdapter(clazz);
}
Btw. the IPresenceContainerAdapter works fine. Any idea?
Has the org.eclipse.ecf.provider.xmpp.remoteservice bundle been deployed
and registered?
Just to follow up with an explanation of why this fragment is
necessary: the xmpp.remoteservice bundle re-uses the ECF generic
implementation of the IRemoteServiceContainerAdapter...it does this by
creating an IAdapterFactory extension (specifically,
XMPPRemoteServiceAdapterFactory).
This extension is then processed and used to respond with non-null
IRemoteServiceContainerAdapter in the return super.getAdapter(clazz); in
the XMPPContainer impl of getAdapter(Class clazz).
So that fragment is now necessary (along with it's dependency on
org.eclipse.ecf.provider.remoteservice) to get/use the
IRemoteServiceContainerAdapter for xmpp.
