Re: [riena-dev] Remote Services
hi sonya,

I see what you mean. The text output is of course simply debug output about a possible service that you can call. We only display this information if the call to the server is as "localhost". That means your URL has to say "localhost" and no http proxy is involved. The reason are really security reasons, because you dont want to expose information about protocols, interfaces to an external party (or a possible external party).

Hi Christian,
 
Thanks for your speedy reply.  All means normally?
 
 
“ So clicking on this link [http://localhost/hessian/PingPongWS] will open a page in the browser that says something like this:
calls protocol=hessian, url="" href="http://192.168.14.51/hessian/PingPongWS" style="color: blue; text-decoration: underline; ">http://192.168.14.51/hessian/PingPongWS, interface=org.eclipse.riena.communication.sample.pingpong.common.IPingPong
 
…”
 
And I do not receive the similar information in a browser.

Hi Sofya,
 
Hessian is a webservice not a webapplication. So it cannot talk to your browser (even though it use HTTP). The 405 error simply tells you that you cannot use GET because the Hessian web service protocol is using only POST.
 
The error 500 means that your browser is not sending webservice calls (in the hessian protocol). You can only talk to the hessian web service backend through a hessian client. Not sure what you expected.
 
Riena is about client service applications. Its not a webapp that you can run your browser against. http://www.eclipse.org/riena -> "What is Riena ?"

Hi Christian,
 
thanks for M5. Today I return to Riena again.
Sample for simple remote service PingPong  works OK, but not completely. 
 
When I call in Mozilla : http://localhost:8080/hessian/PingPongWS,  I receive an error:
 
HTTP ERROR: 405
Hessian requires POST
RequestURI=/hessian/PingPongWS
 
If I cause a server through a method post :
 

HTTP ERROR: 500

expected 'c' in hessian input at -1

RequestURI=/hessian/PingPongWS

Hi Sofya,
 
I assume you are using M5 from today ? Yes createAndRegisterProxy still has 3 parameters and the example should work. (in M4 it had 4 parms but we removed the last parameter in the M5 again).
 
Did you look at the description at http://wiki.eclipse.org/Riena_Getting_started ? It shows you step by step how to import a simple Remote service example from the Riena platform and get it running. Then simply look at the source code and there you have it.
 
If that doesnt help, let me know

Hi Riena Developers,
 
I am interested in the remote services of the Riena and I am currently trying to make a small sample.
 
Tell me please, are examples on page    http://wiki.eclipse.org/Riena_Getting_started_remoteservices
still actual?  For example, here... A method  RemoteServiceFactory().createAndRegisterProxy() has 3 parameters.
 
Where could I get a simple actual example of the Riena remote service?
 
Thanks alot!
 
Best regards
