hi
good
check this code
Ask your system Admin for servername,portnumber of database server
Connection conn=null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn =DriverManager.getConnection ("jdbc:oracle:thin:@<servername>:<portnumber>:DB","uname", "pwd");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from <tablename>"); // select statment
while(rs.next())
IXXElement nodeConnection=wdContext.createXXElement(); //creating a node to store the data from oracle
nodeConnection.setYY(rs.getInt("YY")); // setting the values into input fields
nodeConnection.setAA(rs.getInt("AA"));
nodeConnection.setBB(rs.getInt("BB"));
wdContext.nodeXX().addElement(nodeConnection); // adding the node
catch(Exception ex)
finally
try
conn.close(); // closing the connection
catch(Exception e)
