How to print out details of an exception in an Orbix 3.3 per-process filter.

Environment

Orbix 3.3, All Supported OS

Question/Problem Description

How to print out details of an exception in an Orbix 3.3 per-process filter.

Clarifying Information

A per-process filter can monitor ten individual points during the transmission and reception of an operation or attribute request:

• four Pre-marshalling Filter Points
• four Post-marshalling Filter Points
• two Failure Points

• out reply failure (in the target object’s address space)
• in reply failure (in the caller’s address space)

Resolution

Use the Environment parameter to access the details of the exception as shown in the code below.

void MyProcessFilter::outReplyFailure (CORBA::Request &r, CORBA::Environment &env)
{
    CORBA::Exception *e = env.exception();

    cout << endl << "In outReplyFailure, operation "
        << r.operation () << " Raised Exception. " << endl;

    if (e) {
        cout << "Exception is: " << e->_toString() << endl;
    }
        
    return;
}

void MyProcessFilter::inReplyFailure (CORBA::Request &r, CORBA::Environment &env)
{
    CORBA::Exception *e = env.exception();

    cout << endl << "In inReplyFailure, operation "
        << r.operation () << " Raised Exception. " << endl;

    if (e) {
        cout << "Exception is: " << e->_toString() << endl;
    }

    return;
}
