Java 7 retrieve and read local file using fileinput stream

Question

How can i retrieve and read local file using fileinputstream using Java 7. Something like this but for a local file. With the new security settings, I cant get it to work

public static InputStream openReading(String file)
    throws FileNotFoundException
{
try
{
    PersistenceService pService = (PersistenceService) ServiceManager
            .lookup(PersistenceService.class.getCanonicalName());
    URL fileurl = new URL(getCode() + file);
    FileContents fc= pService.get(fileurl);
    fc.setMaxLength(10240000);
    InputStream in= fc.getInputStream();
    return stream;
}
catch (MalformedURLException m)
{
    m.printStackTrace();
}
catch (FileNotFoundException f)
{   
    throw new FileNotFoundException(f.getMessage());   
}
}

ExtendedService.openFile is the equivalent for opening a file. That gives read/write access. There is no option to ask for read-only!
