I ma trying to use this class for databse connection but the code is not compiling and I am getting missing return statement error.
I am not able to debug it. PLease help.

Here is the code

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import oracle.jdbc.driver.*;


public class DatabaseConnection{

Connection connection = null;
String present = "";
public String getDBname()
{
try {
// Load the JDBC driver
String driverName = "oracle.jdbc.driver.OracleDriver";
Class.forName("oracle.jdbc.driver.OracleDriver");

// Create a connection to the database
String serverName = "135.51.32.169";
String portNumber = "1521";
String sid = "admindb";
String url = "jdbc racle:thin:@" + serverName + ":" + portNumber + ":" + sid;
String username = "amst";
String password = "b1indne$$";
connection = DriverManager.getConnection(url, username, password);
Statement stmt = connection.createStatement();

ResultSet firstdb;
firstdb = stmt.executeQuery("SELECT present FROM auser.sid");
while ( firstdb.next() )
{
present = firstdb.getString("present");
System.out.println("The output we getting from auser.sid is "+present);
}
connection.close();
}

Your method "getDBname()" is declared as returning String, but there are no "return" statements in it anywhere. You could either change that "String" to "void", or have the method return something.

Since we're really talking about Java fundamentals, here, I'm going to move this to our Java beginner's forum.
