Android app connect to MsAccess Database using jackcess

Hi guys,

Iam new in developing android applications.
I want to use Jackcess in Android-App for access an existing accdb database.
I'm using eclipse juno.

My jar files:
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.0.7.jar
jackcess-encrypt-2.0.2.jar
jtds-1.3.1.jar
log4j-1.2.7.jar

My code:
package com.example.siferfinal;
import java.io.File;
import java.io.IOException;
import com.healthmarketscience.jackcess.Database;
import com.healthmarketscience.jackcess.DatabaseBuilder;
import com.healthmarketscience.jackcess.Table;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ConectarBD();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

public void ConectarBD(){
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
System.setProperty("com.healthmarketscience.jackcess.brokenNio","true");
System.setProperty("com.healthmarketscience.jackcess.resourcePath ","res/raw/");
try
{
Database db = DatabaseBuilder.open(new File("sif.mdb"));
Table tblTempoAnt = db.getTable("tblTempoAnt");
System.out.println(tblTempoAnt.toString());
}
catch (IOException e)
{
e.printStackTrace();
}
}

Public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

I added my database to res/raw folder.
On the next line
Database db = DatabaseBuilder.open(new File("sif.mdb"));
I get an error - "java.io.FileNotFoundException: given file does not exist: sif.mdb"
What am i doing wrong ?
