Exception when initiating a session using mina-core-0.9.3.jar

When executing this code:

// make sure we have no ongoing efforts...
m_session = null;
m_initiator = null;

// now set up our QuickFIX application and initiator...
try {
SessionSettings v_settings = new SessionSettings( m_settings );
m_settings.reset(); // so we can use them again as needed...
MessageStoreFactory v_store = new JdbcStoreFactory( v_settings );
LogFactory v_log = new JdbcLogFactory( v_settings );
MessageFactory v_msg = new DefaultMessageFactory();
>>>>>> m_initiator = new ThreadedSocketInitiator( m_app, v_store, v_settings, v_log, v_msg );
m_initiator.start();
ArrayList v_sessions = m_initiator.getSessions();
if( v_sessions.size() > 0 )

{ m_session = Session.lookupSession(( SessionID) v_sessions.get( 0 ) ); }

else

{ log.error( "No sessions exist after starting initiator!" ); }

m_sm.onInitiatorStarted();
}

I get this exception:

java.lang.NoClassDefFoundError: org/apache/mina/protocol/ProtocolProvider

On the line of code indicated. When I substitute mina-0.8.2.jar in the classpath, this code works.
