I'm trying to estabilish a connection to an IBM DB2 database located on the Internet through my Android Application. I added the "db2jcc4.jar" to the Java Build Path,with the following code:
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;
import java.sql.*;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String url = "jdbc:db2://5.10.125.192:50000/SQLDB";
String user = "user";
String password = "password";
Connection connection = null;
try {
Class.forName("com.ibm.db2.jcc.DB2Driver");
connection = DriverManager.getConnection(url,user,password);
} catch (ClassNotFoundException e) {
Toast.makeText(this, "Driver non caricato", Toast.LENGTH_SHORT).show();
} catch (SQLException e) {
Toast.makeText(this, "Errore con url e credenziali", Toast.LENGTH_SHORT).show();
}
if(connection!= null)
{
Toast.makeText(this, "Connessione riuscita!", Toast.LENGTH_SHORT).show();
}
}
}
I also tried to write the same code in Java without using Android,and it runs perfectly,but when i try to run it on Android,it shows lots of errors. There's the logcat:
