Question

Hi All,
Can anyone send sample programs in XI.
jsp-> controller-> database
how much scope of the java we are going to use in XI.
Thank you
with best regards

a sample program for adapter module: this has the main process function...
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData)
throws ModuleException
Object obj = null; // Handler to get Principle data
Message msg = null; // Handler to get Message object
try
obj = inputModuleData.getPrincipalData();
msg = (Message)obj;
try
XMLPayload xmlpayload = msg.getDocument();
String messageStr = xmlpayload.getText();
String inputStr = null;
String tags[] = new String[2];
String values[] = new String[2];
String tagvalue1 = messageStr.substring(messageStr.indexOf("BEGIN+"), messageStr.indexOf("'");
String tagvalue2 = messageStr.substring(messageStr.indexOf("'"), messageStr.lastindexOf("ENDING");
tags[0] = "tag1";
tags[1] = "tag2";
values[0] = tagvalue1 ;
values[1] = tagvalue2 ;
Document xmldoc = null;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
DOMImplementation impl = builder.getDOMImplementation();
org.w3c.dom.Element e = null;
Node n = null;
xmldoc = impl.createDocument(null, "MT940", null);
org.w3c.dom.Element root = xmldoc.getDocumentElement();
for(int i = 0; i < tags.length; i++)
e = xmldoc.createElementNS(null, tags);
n = xmldoc.createTextNode(values);
e.appendChild(n);
root.appendChild(e);
DOMSource domSource = new DOMSource(xmldoc);
ByteArrayOutputStream myBytes = new ByteArrayOutputStream();
Result dest = new StreamResult(myBytes);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty("indent", "yes");
serializer.transform(domSource, dest);
byte[] docContent = myBytes.toByteArray();
if (docContent != null) {
xmlpayload.setContent(docContent);
inputModuleData.setPrincipalData(msg);
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"sample: Inside sample Module---after setting principal data");
catch(ArrayIndexOutOfBoundsException e)
e.printStackTrace();
catch(StringIndexOutOfBoundsException e)
e.printStackTrace();
catch(TransformerException e)
e.printStackTrace();
catch(Exception e)
e.printStackTrace();
catch(Exception e)
ModuleException me = new ModuleException(e);
throw me;
return inputModuleData;
