Hello Stephan,
thanks for your fast answer.

IIRC, UNO remote bridge protocols are found by library name. That is,
if you have a protocol named xyz (and corresponding accept strings/UNO
URLs would be of the form "...;xyz..." instead of the familiar
"...;urp..."), its implementation would be in in a dynamic library
called libxyz_uno.so (on Unix), similar to the existing liburp_uno.so.
I did not know that it's as easy as to have a corresponding library. So
it is enough, if I have built such a library, to copy the new library
into the program directory and then the protocol will be recognized (that
means there is no registry entry or something similar necessary)?
I'm really not sure about the details. If you encounter any problems,
report back and I'll see if I can find some time to dig into that.

Hi Stephan,
meanwhile I have found out that there must exist a service in the service
registry. For the urp protocol it is the line with UrpBridge:
/ com.sun.star.comp.remotebridges.Bridge.various
/ UNO
/ ACTIVATOR
Value: Type = RG_VALUETYPE_STRING
Size = 34
Data = "com.sun.star.loader.SharedLibrary"
/ SERVICES
/ com.sun.star.bridge.UrpBridge <=====
existing urp protocol
/ com.sun.star.bridge.UrtpBridge <===== my new
protocol urpt
/ com.sun.star.bridge.Bridge
/ com.sun.star.bridge.IiopBridge
/ LOCATION
Value: Type = RG_VALUETYPE_STRING
Size = 20
Data = "remotebridge.uno.so"
Can you give me a hint/link to docu how to add that line "UrtpBridge" to the
services database (I have produced the above with the regview command) and
could that be enough for load the library liburtp_uno.so with my text-based
frontend?
Thanks,
Arnulf
A bridge for protocol xyz must be a UNO service implementation that
simultaneously supports the UNO service "com.sun.star.bridge.Bridge" and
the UNO service "com.sun.star.bridge.xyzBridge" (where the "xyz" part
can be any mixture of upper and lower case), see
remotebridges/source/factory/bridgefactory.cxx.
What you found in services.rdb is the service implementation named
"com.sun.star.comp.remotebridges.Bridge.various" that happens to be the
only bridge implementation available in a default OOo. It happens to
support two protocols, "urp" and "iiop" (which is dead code).
To introduce a bridge for a new protocol "urtp", you would either need
to write a UNO component that supports the UNO services
"com.sun.star.bridge.Bridge" and "com.sun.star.bridge.UrtpBridge" (see
the UNOIDL documentation of com.sun.star.bridge.Bridge, and the
Developer's Guide on general information about developing and deploying
UNO components). Or you hack your protocol into the existing
"com.sun.star.comp.remotebridges.Bridge.various" implementation, see
remotebridges/source/bridge/remote_bridge.cxx (since you want to re-use
the existing urp code, it might work to patch ORemoteBridge::initialize
so that if the protocol name in swProtocol is "urtp", you change it to
"urp"; swProtocol will contain the complete protocol string, consisting
of the protocol name followed by zero or more parameters of the form
",KEY=VALUE").
