Attempting to connect to iSeries from simple PC program

        This is a beginner's question.  We are trying to provide access
to provide access to the AS400 from a PC as part of a larger project.  I
am not using an IDE - just a text editor and the DOS command line, right
now.

        On the list there was a simple access test called
CheckConnect.java, and I compiled and ran that, and I was able to
connect to the extent that the following code worked:

      AS400 as400 = new AS400(); 
      SystemValue model = new SystemValue(as400, "QMODEL"); 
      SystemValue serial = new SystemValue(as400, "QSRLNBR"); 

      as400.connectService(AS400.COMMAND); 

      System.out.println("System: " + as400.getSystemName()); 
      System.out.println(" Model: " + model.getValue()); 
      System.out.println("Serial: " + serial.getValue());

        
        I was prompted for the system, my user ID and password, and I
got back the system values.

        However, when using a sample program in the IBM Toolbox for Java
manual from InfoCenter, my connection is consistently refused.  I am
using code like this:


        // Create AS400 obj and connect for the record level access
service.
      AS400 iSeriesSystem = new AS400(systemName);
      try
      {         
         iSeriesSystem.connectService(AS400.RECORDACCESS);
      }
      catch(Exception e)
      {             
         e.printStackTrace();
         System.exit(0);
      }


        Again, I sign on using my system's TCP/IP address, my user id
and password, but this time I get a series of errors:

com.ibm.as400.access.InternalErrorException: Data stream is not known.

)
at com.ibm.as400.access.AS400.connectService(AS400.java:703)
 at RLSeqAccEx.main(RLSeqAccEx.java:64)


        No logs have been found on the iSeries to cover this rejection.


        Any an all help would be greatly appreciated.  We would like to
explore some Java solutions that require remote connections.
