public class DataHandler {
    public DataHandler() throws Exception {
    String jdbcUrl = "jdbc:oracle:thin:@//localhost:1521/XE";
    String userid = "hr";
    String password = "hr";
    Connection conn;

    public String getColumnName(int col){

    public Object getValueAt(int row, int col){
        return tempTable.getValueAt(row,col);
    public JTable getClients(int departmentId) throws Exception {
        getDBConnection();
        try {
            stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
            res=stmt.executeQuery("SELECT * FROM Employees");
            ResultSetMetaData RSMD=res.getMetaData();
            NumberOfColumns=RSMD.getColumnCount();
            AttributeNames=new String[NumberOfColumns];
            for(int i=0; i<NumberOfColumns; i++)
                AttributeNames=RSMD.getColumnName(i+1);
Object[][] MyArray=new Object[1000][NumberOfColumns];
int R=0;
while(res.next()) {
//if(departmentId == res.getInt("DEPARTMENT_ID")){
for(int C=1; C<=NumberOfColumns;C++)
MyArray[R][C-1]=res.getObject(C);
R++;
res.close();
NumberOfRows=R;
Object[][] TempArray=MyArray;
MyArray=new Object[NumberOfRows][NumberOfColumns];
for(R=0;R<NumberOfRows;R++)
for(int C=0;C<NumberOfColumns;C++)

tempTable = new JTable(MyArray, AttributeNames);
return tempTable;
catch(Exception e) {
e.printStackTrace();
return null;
public JComboBox getDepartments() throws Exception {
getDBConnection();
try {
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
res=stmt.executeQuery("SELECT * FROM Departments");
JComboBox jtempBox = new JComboBox();
while (res.next()){
jtempBox.addItem(res.getString("DEPARTMENT_NAME"));
return jtempBox;
catch(Exception ex){
return null;
public int getDepartmentId(String departmentName) throws Exception {
getDBConnection();
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
res=stmt.executeQuery("SELECT * FROM Departments WHERE DEPARTMENT_NAME='" + departmentName +"'");
while (res.next()){
if (res.getString("DEPARTMENT_NAME").equals(departmentName))
return res.getInt("DEPARTMENT_ID");
return 0;
here is the code for the DataHandler. i'm simply using a dummy database right now.
