SOAP lookups from withing message mapping

Question

Hi
   We are doing a call to a webservice from within a udf in a message mapping using the SOAP API described in one of the blogs in SDN. We are using a soap receiver communication channel to make this webservice call -
We see activity on the communication channel monitoring - indicating that there is a call going out and a response coming back from the webservice. But there are no details shown on the payload in communication channel monitoring. We do not see this webservice lookup as a message on the adapter engine either ?
Is there any place from within XI runtime environment we can get a hold of the message going out to webservice call and the return from webservice ?  We are facing problems in the webservice not doing the required action desired and hence this question on visibility of the call to the webservice.
Thanks in advance for your time.

My udf is basically makes a call to the webserservice lookup method ( line - CallCentralMonitoring.LogToCentralMonitoring( "IN130.10", "COMPLETED"); ) - the definition of CallCentralMonitoring class is given below after the udf
UDF
String adapter = "RECEIVE_FusionDBLookUpRequest";
Channel channel = null;
boolean retry = false;
int noOfRetries = 0;
String sqlQuery = new String("");
DataBaseAccessor accessor = null;
DataBaseResult resultSet = null;
String parameterValue = new String("");
MappingTrace trace = container.getTrace();
// Build the Query String
//sqlQuery = "select * from CTL_BusinessRules with (nolock) where parameter_key = '" + parameterKey + "'";
sqlQuery = "exec uspCTL_GetBusinessRule '" + parameterKey + "'";
do
     try
          //trace.addInfo( "SQL query is: " + sqlQuery);
          // Determine a channel, as created in the Configuration
          channel = LookupService.getChannel(businessService,adapter);
          // Get a system accessor for the channel. As the call is being made to a DB, a DatabaseAccessor is obtained.
          accessor = LookupService.getDataBaseAccessor(channel);
          //trace.addInfo( "Successfully obtained the system accessor..." );
          // Execute Query and get the values in resultset
          resultSet = accessor.execute(sqlQuery);
          Iterator rows = resultSet.getRows();
          //trace.addInfo( "Executed query successfully..." );
          while( rows.hasNext() )
               Map rowMap = (Map)rows.next();
               parameterValue =  rowMap.get("CHARACTER_VALUE").toString();
               //trace.addInfo( "Parameter Value is: " + parameterValue );
          retry = false;
          CallCentralMonitoring.LogToCentralMonitoring( "IN130.10", "COMPLETED");
          return parameterValue;
     catch( Exception ex )
          //trace.addInfo( ex.toString() );
          if ( noOfRetries < 3 )
               retry = true;
               noOfRetries++;
          else
               retry = false;
               CallCentralMonitoring.LogToCentralMonitoring( "SD152.01", "Error");
               ExceptionThrower.fire( "Database connectivity error: " + ex.toString() );
     finally
          try
               if ( accessor != null ) accessor.close();
          catch( Exception e )
               ExceptionThrower.fire("Error closing accesor: " + e.getMessage() );
               //return e.getMessage();
} while( retry );
return null;
