Apps Oracle database connection using jbdc

[mogly]

Hi all
I am trying to communicate with an oracle database using jbdc, I need to read and write to the database, I dont have server access so have to commincate directly with the database. At the moment I am struggling to even get a connection. The app only needs to be simulated on a secure network so I am not too worried about security issues.
code im using:

package com.tentantrepairs;

import java.sql.Connection;
import java.sql.DriverManager;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class TenantRepairs extends Activity{
	@Override
	public void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	TextView tv = new TextView(this);
	tv.setText("orcale Connect Example.");
	setContentView(tv);
	
	Connection conn;
	String url = "jdbc:oracle:thin:@blah.blah.blah.ac.uk:1522:orcl";
	String userName = "PRCSF"; 
	String password = "PRCSF";
	try {
		Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
	  conn = DriverManager.getConnection(url,userName,password);
	  tv.setText("Connected to the database");
	} catch (Exception e) {
		tv.setText("nope");
	}
	}
	}

Many thanks Ben
