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());
}
