RFAJ8.0 ConfigDb, unable to acquire a Session
Hello,
I'm trying to initialize Context using a ConfgDb instance :
configDb.addVariable("com.reuters.rfa.TestDistrib.Connections.TestDistrib.serverList","spl-trep-101");
configDb.addVariable("com.reuters.rfa.TestDistrib.Connections.TestDistrib.portNumber","14002");
configDb.addVariable("com.reuters.rfa.TestDistrib.Connections.TestDistrib.connectionType","RSSL");
configDb.addVariable("com.reuters.rfa.TestDistrib.Sessions.TestDistrib.connectionList","TestDistrib");
Context.initialize(configDb); // returns OK
Session.acquire("TestDistrib"); // returns null
I also tried to acquire a session using string "com.reuters.rfa.TestDistrib" but it didn't work either.
I know it's a beginner question but.. can anyone help ?
In advance thank you.
Hello @claude.thomas,
In the configuration settings via ConfigDb, you can omit 'com.reuters.rfa.' for the first parameter (scopedVarName).
Kindly modify the source code to be as follows:
configDb.addVariable("TestDistrib.Connections.TestDistrib.serverList","spl-trep-101");
configDb.addVariable("TestDistrib.Connections.TestDistrib.portNumber","14002");
configDb.addVariable("TestDistrib.Connections.TestDistrib.connectionType","RSSL");
configDb.addVariable("TestDistrib.Sessions.TestDistrib.connectionList","TestDistrib");
Context.initialize(configDb); // returns OK
Session.acquire("TestDistrib::TestDistrib"); // returns null
In the snippet code above, please see the meaning of strings' position below.
- configDb.addVariable("<nameSpace>.Sessions.<sessionName>.connectionList","TestDistrib");
- configDb.addVariable("<nameSpace>.Connections.<connectionName>.serverList","spl-trep-101");
- configDb.addVariable("<nameSpace>.Connections.<connectionName>.portNumber","14002");
- configDb.addVariable("<nameSpace>.Connections.<connectionName>.connectionType","RSSL");
- Session.acquire("<nameSpace>:<sessionName>");
Note that a character '.' is not allowed for the <nameSpace> string value. If you try to use a nameSpace that contain it. For example; com.reuters.rfa.TestDistrib, RFA will return the following error message:
// A result from..
// Session.acquire("com.reuters.rfa.TestDistrib::TestDistrib");

Hope this helps!
Hello,
Thank you very much, it now works.
Indeed, I didn't correctly set the parameter for Session.acquire method.
