I'm beginner for using JPOS with ISO8583. At this time, I try my application using Spring to build the request using JPOS where I want to send it to BASE24.
Here my code for build :
public class BuildISO {
public void sentISOMsg(String hostname, int portNumber) {
// Create Packager based on XML that contain DE type
GenericPackager packager;
ASCIIChannel channel;
try {
packager = new GenericPackager("packager/iso93ascii.xml");
channel = new ASCIIChannel(hostname, portNumber, packager);
ISOMUX isoMux = new ISOMUX(channel) {
@Override
protected String getKey(ISOMsg m) throws ISOException {
return super.getKey(m);
}
};
new Thread(isoMux).start();
// Create ISO Message
ISOMsg isoRequest = new ISOMsg();
isoRequest.setMTI("1800");
isoRequest.set(3, "123456");
isoRequest.set(7, new SimpleDateFormat("yyyyMMdd").format(new Date()));
isoRequest.set(11, "000001");
isoRequest.set(12, new SimpleDateFormat("HHmmss").format(new Date()));
isoRequest.set(13, new SimpleDateFormat("MMdd").format(new Date()));
isoRequest.set(48, "Tutorial ISO 8583 Dengan Java");
isoRequest.set(70, "001");
ISORequest req = new ISORequest(isoRequest);
isoMux.queue(req);
ISOMsg isoReply = req.getResponse(50*1000);
if (isoReply != null) {
System.out.println("Req ["+new String(isoRequest.pack()) + "]");
System.out.println("Res ["+new String(isoReply.pack()) + "]");
}
// print the DE list
logISOMsg(isoRequest);
// Get and print the output result
byte[] data = isoRequest.pack();
System.out.println("RESULT : " + new String(data));
} catch (ISOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private static void logISOMsg(ISOMsg msg) {
System.out.println("----ISO MESSAGE-----");
try {
System.out.println(" MTI : " + msg.getMTI());
for (int i=1;i<=msg.getMaxField();i++) {
if (msg.hasField(i)) {
System.out.println(" Field-"+i+" : "+msg.getString(i));
}
}
} catch (ISOException e) {
e.printStackTrace();
} finally {
System.out.println("--------------------");
}
}
}
and next, while I want to call that class in here :
public @ResponseBody ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
String hostname = request.getParameter("hostname");
int portNumber = Integer.parseInt(request.getParameter("portNumber"));
System.out.println("handleRequest... : " + hostname + " : " + portNumber);
BuildISO buildISO = new BuildISO();
buildISO.sentISOMsg(hostname, portNumber);
return null;
}
I got error like this :

I have searched through StackOverflow's already asked questions, but have not found any of the situations in which the changes to the project were NONE. So I am feeling quite frustrated now because I have actually changed NOTHING and my project has stopped working. Help me please, any ideas would be grateful.
You should be sure that you have all jars in the CLASSPATH. In your case it is jpos.jar. And they all (with Spring) should be loaded withing the same classloader.
And one more advice: add -verbose option to the java (I guess Tomcat) to see from where your classes are loaded.
