Re: connection error (retrieveRecordFormat?)

Your program looks good (I copied it into a test case and it connected to
my AS/400, then crashed because it could not find library ljptest).  In
your case the program ends where it does because that is the first time the
Toolbox needs to access the AS/400.  You talk about your firewall.  Is it
configured for data transmission in both directions?  Do you have a machine
behind the firewall to see if you can connect to your AS/400 when the
firewall is not in the picture?  That will help determine if the AS/400 or
the firewall is the problem.  Check the QUSER profile to make sure it is
enabled.  The server jobs start as QUSER then switch to the user specified
profile to do actual work.

Subject:  connection error (retrieveRecordFormat?)




Please have patience with what's probably a stupid mistake.

I am trying to make a demo data queue program from AS400 Network Expert
(may/june 2000) work on my system.  I made some modifications to set it up
for my environment but am having trouble getting it to connect to the
AS400.
The sign on window appears and I fill it in but then it fails with the
following error:
"java.net.ConnectException: Connection refused: no further information"

I put the source that is getting the error at the end of this message.
Please forgive my primitive debugging. The failure appears to be in the
execution of the retrieveRecordFormat.
"pList[0]:" & "pList[1]:" both come up but then I get the connection
refused error and no "pList[1a]:"

I checked the system name.
I checked the file name (LJPTEST/PRDMST).
The firewall shows activity on ports assigned to the signon server then on
the port mapper and finally on the DDM server before failing.
STRTCPSVR *DDM says the server is already active.

1 - Do you see my error?
2 - Where can I look on the 400 for any logging information about what it
thinks is happening and maybe a more explicit error message?
3 - Any other ideas for debugging this type of stuff?

Thanks for any help or ideas,

Here is the section of code that is executing:

public class Inv013Dtaq {
  DataQueue dtaqIn, dtaqOut;
  AS400 sys;
  RecordFormat dtaqFormat;
  public Inv013Dtaq() {
    sys = new AS400("S100BFDD");
    System.out.println("pList[0]: ");

    AS400FileRecordDescription recDesc =
      new AS400FileRecordDescription(sys,
         "/QSYS.LIB/LJPTEST.LIB/PRDMST.FILE");
    System.out.println("pList[1]: ");
    try {
      dtaqFormat = recDesc.retrieveRecordFormat()[0];
    System.out.println("pList[1a]: ");
      dtaqIn = new DataQueue(sys,
        "/QSYS.LIB/LJPTEST.LIB/JAVADTAQO.DTAQ");
    System.out.println("pList[1b]: ");
      dtaqOut = new DataQueue(sys,
        "/QSYS.LIB/LJPTEST.LIB/JAVADTAQI.DTAQ");
    System.out.println("pList[1c]: ");
    } catch (Exception e) {
      System.out.println(e);
    }
  }
