Hi Bris ,
The sample code , you didnt specified from where do u want to access the oracle thorough java code or through webdynpro .
Sample code to access through Java
import java.sql.*;
class Customer
public static void main(String args[]) throws SQLException
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
System.out.println("Connecting to the database...");
try
Connection cn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","scott","t");
Statement st=cn.createStatement();
ResultSet rs=st.executeQuery("select 'Connected' from dual");
rs.next();
String s=rs.getString(1);
System.out.println(s);
st.close();
cn.close();
catch(Exception ex)
System.out.println("The exception raised is:" + ex);

      * @return
     public Connection getConnection() {
          try
               Context jndiContext = new InitialContext();
               DataSource ds = (DataSource)jndiContext.lookup("jdbc/MyAlias");
               connection = ds.getConnection();
         catch(Exception connectionErrEx)
               //connectionErrEx.printStackTrace();
