problem using sandesha
Hi
Has anyone been able to use sandesha outside the
interop examples ?...I have been trying to get a very
simple echo service (userguide\example3\MyService.java
in axis samples) to work but I am having some trouble.
It looks like the create-sequence request and
response messages are exchanged correctly but after
that the invoke() request does not seem to be reaching
the service. I have followed the userguide client-side
and server-side instructions in setting up this
scenario.
On running the client, following output is generated:
=========================
C:\Tomcat\axis-1_2RC2>java
samples.userguide.example3.Client
-lhttp://127.0.0.1:8070/axis/services/MyService "A"
INFO: SENDER STARTED ....
NFO: CLIENT LISTENER STARTED ....
INFO: SENDING CREATE SEQUENCE REQUEST ....
INFO: SENDING REQUEST MESSAGE ....
INFO: SENDING REQUEST MESSAGE ....
=========================
While tomcat (running the sandesha enabled MyService)
prints the following statements:
=========================
INFO: SENDER STARTED ....
INFO: RMINVOKER STARTED ....
INFO: SENDING CREATE SEQUENCE RESPONSE ....
=========================
axis.log on the client side has the following logs:
=========================
id does not exist
86625 ERROR [main] (SandeshaQueue.java:574) -
Sequence id does not exist
86805 ERROR [Thread-0] (Sender.java:105) -
org.apache.axis.types.URI$MalformedURIException:
Cannot initialize URI with empty parameters.
87126 ERROR [main] (SandeshaQueue.java:574) -
Sequence id does not exist
87626 ERROR [main] (SandeshaQueue.java:574) -
Sequence id does not exist
=========================
the MalformedURIException exception could be the
problem but I am not sure whats causing it. As can be
seen in the client logs above the service url being
passed to the client is:
-http://127.0.0.1:8070/axis/services/MyService
My modifications to the Client.java are based on the
EchoClientAsyncAck.java interop sample. ie.
1. RMInitiator.initClient(false);
2. call.setProperty(Constants.ClientProperties.SYNC,
new Boolean(false));
3. call.setProperty(Constants.ClientProperties.ACTION,
""); ( This is different from the interop
example...here unlike EchoClientAsyncAck.java I am
setting ACTION property to an empty string as thats
the value in the wsdl for MyService)
4.call.setProperty(Constants.ClientProperties.FROM,"http://127.0.0.1:"+defaultClientPort+"/axis/services/RMService");
5.
call.setProperty(Constants.ClientProperties.REPLY_TO,"http://127.0.0.1:"+defaultClientPort+"/axis/services/RMService");
(defaultClientPort=9070, tcp mon is running to forward
it to 9090)
6.call.setTransport(new RMTransport(endpointURL, ""));
(endpointURL=http://127.0.0.1:8070/axis/services/MyService)
Could anyone suggest what I might be doing wrong ?
Thanks,
Aditya

Hi Aditya,
The error is not something to do with your code. It is the Action URI that
causes the problem. Sandesha uses Action property to identify different
services from the client side. I will correct this soon so that it will use
the target URL to identify different services in the client side. Then we
don't have to depend on the action property anymore.
Until such time please set a valid action in the client.
e.g. call.setProperty(Constants.ClientProperties.ACTION,"urn:abc");
The error due to malformed URI is mainly due to not complying with the URI
schemes. For more information on URIs please refer.
http://www.gbiv.com/protocols/uri/rfc/rfc3986.html#examples
btw; This is the client class that I used

String ret = (String) call.invoke( new Object[] { "Hello" } );
System.out.println("You typed : " + ret);
RMInitiator.stopClient();
} catch (Exception e) {
System.err.println(e.toString());
}
