我如何使用Java代码来调用AS400 PGM添加DB2库

Question

我打电话使用Java代码的AS400程序。调用成功时，程序简单，而不是试图以任何DB2表来写。当我尝试调用它试着在DB2表写另一个程序的不成功，因为我要补充与此有关表的DB2库。我要补充使用Java代码库。一个例子是使用ColdFusion代码来添加这些库给了我。我想知道如何添加使用Java代码的DB2库。

private static final String HOST = "XXX.XXX.XXX.XXX";
private static final String UID = "XXX";
private static final String PWD = "XXX";

String fullProgramName = "/QSYS.LIB/TSTOBJ.LIB/GETAB.PGM";
String input = "12345678";
AS400 as400 = null;
byte[] inputData;
byte[] outputData;
String  SCAB;
AS400Text textData;
ProgramParameter[] parmList;
ProgramCall programCall;

try {
            // Create an AS400 object
            as400 = new AS400(HOST, UID, PWD);
            // Create a parameter list
            // The list must have both input and output parameters
            parmList = new ProgramParameter[2];
// Convert the Strings to IBM format

        inputData = input.getBytes("IBM285");

            // Create the input parameter  

        parmList[0] = new ProgramParameter(inputData);

            // Create the output parameter
            //Prarameterised Constructor is for the OUTPUT LENGTH. here it is 10
            parmList[1] = new ProgramParameter(20);


            /**
             * Create a program object specifying the name of the program and
             * the parameter list.
             */
            programCall = new ProgramCall(as400);
            programCall.setProgram(fullProgramName, parmList);
            // Run the program.  
            if (!programCall.run()) {
                /**
                 * If the AS/400 is not run then look at the message list to
                 * find out why it didn't run.
                 */
                AS400Message[] messageList = programCall.getMessageList();
                for (AS400Message message : messageList) {
                    System.out.println(message.getID() + " - " + message.getText());                

                }
            } else {
                /**
                 * Else the program is successfull. Process the output, which
                 * contains the returned data.
                 */
            outputData = parmList[1].getOutputData();
                  SCAB = new String(outputData, "IBM285").trim();

               /* System.out.println("Output is " + SCAB );*/
            }

        } catch (PropertyVetoException | AS400SecurityException | ErrorCompletingRequestException | IOException | InterruptedException | ObjectDoesNotExistException e) {
            System.err.println(":: Exception ::" + e.toString());
        } finally {
            try {
                // Make sure to disconnect 
                if (as400 != null) {
                    as400.disconnectAllServices();
                }
            } catch (Exception e) {
                System.err.println(":: Exception ::" + e.toString());
            }

使用commandcall执行命令。请参见下面的链接了解详情。
