We use the second approach. It looks something like that:
public String readIOR() 
  {
    InputStream iorInputStream = null;
    String input=null;
    try
    {
      iorInputStream = iorURL.openStream();
    }
    catch(IOException ioe)
    {
      ioe.printStackTrace(System.out);
    }

    DataInputStream iorDataInputStream = new DataInputStream(iorInputStream);
    try
    {
      input = iorDataInputStream.readLine();
    }
    catch(IOException ioe)
    {
      ioe.printStackTrace(System.out);
    }
    return input;
  }

For convenience we write the Stringified IOR of the server and the nameserver
to a defined file at startup with a little script like that:

#!/bin/sh
/usr/local/JavaIDL/bin/nameserv -ORBInitialPort 8088 > /home/mamue/javaIDL.log &
sleep 4
grep IOR /home/mamue/javaIDL.log > /home/mamue/javaIDL.ior
cd /home/mamue/programming/corba/java
/usr/local/jdk1.1.1/bin/java -classpath /usr/local/jdk1.1.1/lib/classes.zip:/usr
/local/JavaIDL/lib/classes.zip:. pictureServer -ORBInitialPort 8088 &
cd -

Hope this helped
