Dear Ryu,
Thanks very much, indeed it was user error and I did not set -midas option at the compilation stage.

Did you run ROMEBuilder for your application with -midas option ?
With this option, MIDAS library is linked to the application for communicating with MIDAS experiments.
Actual connection is done with using a function implemented in the MIDAS library.
This is the code where a ROME application connects to MIDAS.
(You can see this in $ROMESYS/src/ROMEMidasDAQ.cpp)
cm_connect_experiment is implemented in $MIDASSYS/src/midas.c
//______________________________________________________________________________
Bool_t ROMEMidasDAQ::ConnectExperiment(ROMEMidasDAQ *localThis)
{
// Connect to the experiment
#if defined( HAVE_MIDAS )
if (cm_connect_experiment(const_cast<char*>(gROME->GetOnlineHost()),
const_cast<char*>(gROME->GetOnlineExperiment()),
const_cast<char*>(gROME->GetOnlineAnalyzerName()), 0) != SUCCESS) {
ROMEPrint::Error("\nCan not connect to experiment\n");
return kFALSE;
}
Can you check if this function is called by adding
cout<<"HERE"<<endl;
before the 'if' line and compile your application ?
If you didn't use -midas option when you run ROMEBuilder, HAVE_MIDAS will not be defined and cm_connect_experiment will not be called.
When nothing is written in <online> section of XML, I think the application tries to connect to the localhost with the experiment name defined in /etc/exptab.
I didn't mean anything specific about odbedit.
I guess if you can connect the MIDAS system with odbedit, then the system is ready to accept analyzer too.
But you could ask also MIDAS experts about this issue.
