ERROR - oracle.jdbc.pool.OracleDataSource - oracle

Question

I'm trying to develop an adf mobile app using jDeveloper and oracle sql developer.
I have connected jDev and sql. I want to populate selectOneChoice comp. that I m gonna fetch datas.
this is my connection method;
package salesorder.application;
import groovy.sql.Sql;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import javax.sql.DataSource;
import oracle.adf.share.jndi.InitialContextFactoryImpl;
import oracle.adfmf.framework.api.AdfmfJavaUtilities;
import oracle.jbo.server.InitialContextImpl;
import oracle.jdbc.connector.OracleConnectionManager;
import oracle.jdbc.pool.OracleDataSource;
public class DBConnection {
public DBConnection() {
super();
}
private static String jdbcUrl = "jdbc:oracle:thin:#10.172.105.37:1521:VIS";
private static String userid = "***";
private static String password = "***";
protected static Connection conn = null;
public static Connection getConnection()throws Exception{
if (conn == null) {
try {
OracleDataSource ds; ds = new OracleDataSource();
ds.setURL(jdbcUrl);
conn=ds.getConnection(userid,password);
} catch (SQLException e) {
// if the error message is "out of memory",
// it probably means no database file is found
System.err.println(e.getMessage());
}
}
return conn;
}
}
and this, my method to fetch data;
private void Execute() {
Trace.log(Utility.ApplicationLogger, Level.INFO, Customers.class, "Execute",
"!!!!!!!!!!!!!!!!!In COUNTRY Execute!!!!!!!!!!!!!!!!!!!!!!!!!");
try{
Connection conn = DBConnection.getConnection();
customers.clear();
conn.setAutoCommit(false);
PreparedStatement stat= conn.prepareStatement("select cust_account_id,account_name from hz_cust_accounts_all where account_name is not null order by account_name asc");
// fetching customers name
ResultSet rs = stat.executeQuery();
Trace.log(Utility.ApplicationLogger, Level.INFO, Customers.class, "Execute",
"!!!!!!!!!!!!!!!!!Query Executed!!!!!!!!!!!!!!!!!!!!!!!!!");
while(rs.next()){
int id = rs.getInt("CUST_ACCOUNT_ID"); // customer id
String name = rs.getString("ACCOUNT_NAME"); // customer name
Customer c = new Customer(id,name);
customers.add(c);
}
rs.close();
} catch (SQLException e) {
System.err.println(e.getMessage());
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
when i try to start application, an error comes up like that.
i cant use an image. so
Error
oracle.jdbc.pool.OracleDataSource
I dont know how Im gonna solve that, i cannot figure out why . Any help ?

Just to clarify - are you trying to use ADF Mobile (AMX pages)?
If so then you can't connect with JDBC to a remote database from the client.
You can only connect with JDBC to the local SQLite DB on your device.
To access data from remote servers you'll need to expose this data with web services and call those.
