Adding JTextFields and JLabels on a window/panel

Question

Hi everyone,
i am creating a program that reads information from an XML, it can read the XML without any problem. my problem is i have got an Element viz: serviceOrderElement, and i store its values inside a Combobox. that serviceOrderElement has parameters
E.g:
<ServiceOrder name="MPABX_LIST_VPN_MEMBER" description="List enterprise members">
     <parameter>GRPID</parameter>
     <parameter>DEPT</parameter>
     <parameter>POVERDUE</parameter>
     <parameter>STARTDATE</parameter>
     <parameter>ENDDATE</parameter>
     <parameter>ORDER1</parameter>
     <parameter>ORDERTYPE1</parameter>
     <parameter>ORDER2</parameter>
     <parameter>ORDERTYPE2</parameter>
     </ServiceOrder>
     <ServiceOrder name="MPABX_LIST_VPN_HUNTINGNO">
     <parameter>GRPID</parameter>
     <parameter>MAINNUMBER</parameter>
     </ServiceOrder>
so now what i want to do is, when i select a serviceOrder e.g: MPABX_LIST_VPN_MEMBER, i what the program to automatically create Labels and TextFields on an InternalJFrame, meaning because MPABX_LIST_VPN_MEMBER has 9 parameters 9 Labels("Parameter names") and TextField must be created on an internalJFrame, or because MPABX_LIST_VPN_HUNTINGNO has 2parameters 2 Labels("Parameter names") and TextField must be created on an internalJFrame

Answer 1

The question is how can i create Labels and TextField Depending on the number of parameters that exist in a serviceOderElement.
This is my code:
try {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse (new File("ServiceOrderGUIConfig.xml"));
NodeList serviceOrder = doc.getElementsByTagName("ServiceOrder");
int totalServiceOrder = serviceOrder.getLength();
for(int s=0; s<serviceOrder.getLength() ; s++){
Node anAttributeNode = serviceOrder.item(s);
if(anAttributeNode.getNodeType() == Node.ELEMENT_NODE){
Element anAttributeElement = (Element)anAttributeNode;
NodeList para = anAttributeElement.getElementsByTagName("parameter");
test=anAttributeElement.getAttribute("name");
test2=anAttributeElement.getAttribute("description");
if(menu1.getSelectedItem().equals(test))
for(int paramCounter = 0; paramCounter <para.getLength();++paramCounter)
Element parameterElement =(Element)para.item(paramCounter);
NodeList parameterTextList =parameterElement.getChildNodes();
String parameterValue =parameterTextList.item(0).getNodeValue().trim();
System.out.println("\n"+parameterValue);
}//end of if clause
}//end of for loop with s var
for(int counter = 0; counter < serviceOrder.getLength(); ++counter)
Node anAttributeNode = serviceOrder.item(counter);
if(menu1.getSelectedItem().equals(test))
if(anAttributeNode.getNodeType()==Node.ELEMENT_NODE)
Element anAttributeElement = (Element)anAttributeNode;
NodeList para =anAttributeElement.getElementsByTagName("parameter");
for(int paramCounter = 0; paramCounter <para.getLength();++paramCounter)
Element parameterElement =(Element)para.item(paramCounter);
NodeList parameterTextList =parameterElement.getChildNodes();
String parameterValue =parameterTextList.item(0).getNodeValue().trim();
System.out.println("\n"+parameterValue);
System.out.println("=============================================");
//For separating the values
}catch (SAXParseException err) {
String msg = "Error on line " + err.getLineNumber () + "\n, URL " + err.getSystemId ()+"\nMessage"+err.getMessage ();
JOptionPane.showMessageDialog(null,msg,"ERROR!",JOptionPane.ERROR_MESSAGE);
}catch (SAXException e) {
Exception x = e.getException ();
((x == null) ? e : x).printStackTrace ();
}catch (Throwable t) {
t.printStackTrace ();
}
