this is the code to save.
void SavejButton_actionPerformed(ActionEvent e) {
xmlDoc = new XMLDoc("EPOD_USER");
try
Node userConfig = xmlDoc.addNode(xmlDoc.getRootNode(),"USER_CONFIGURATION");
//Compant Infomation
Node company =xmlDoc.addNode(userConfig,"COMPANY_INFOMATION");
xmlDoc.addNode(company,"COMPANY_NAME", SetupCompanyNameJText.getText());
xmlDoc.addNode(company,"COMPANY_TYPE", (String) CompanyTypejComboBox.getSelectedItem());
//Company Phones
Node contact = xmlDoc.addNode(userConfig,"COMPANY_PHONES");
xmlDoc.addNode(contact,"PHONE_1", SetupPhWork1jText.getText());
xmlDoc.addNode(contact,"PHONE_2", SetupPhWork2JText.getText());
xmlDoc.addNode(contact,"FAX", FaxjTextField.getText());
xmlDoc.saveToFile("EPOD" +".xml");
catch (IllegalNodeAddException inae)
System.out.println(inae.getMessage());
System.out.println(xmlDoc);
// System.out.println(xmlDoc);
cancel();
Code to bring it back .
public void setUserConfig(){
xmlDoc = new XMLDoc();
xmlDoc.loadFromFile("Epod.xml");
try
Node company = xmlDoc.getNode("/EPOD_USER/USER_CONFIGURATION/COMPANY_INFOMATION/");
SetupCompanyNameJText.setText(xmlDoc.getValueOf(company,"COMPANY_NAME"));
CompanyTypejComboBox.setSelectedItem(xmlDoc.getValueOf(company,"COMPANY_TYPE"));
Node phone = xmlDoc.getNode("/EPOD_USER/USER_CONFIGURATION/COMPANY_PHONES/");
SetupPhWork1jText.setText(xmlDoc.getValueOf(phone,"PHONE_1"));
SetupPhWork2JText.setText(xmlDoc.getValueOf(phone,"PHONE_2"));
FaxjTextField.setText(xmlDoc.getValueOf(phone,"FAX"));
catch ( NodeNotFoundException nnfe)
System.out.println(nnfe.getMessage());
}

Answer 1

well, if this SetupPhWork1jText.getText() is null, then you try adding a null node and it explodes...
