Why are you returning stream reader instead of xml document ?

Hi,
I am trying to create a service to return an
instance of XMLStreamReader.
I have four simple code and I got an error
as follows.
Echo.java
import javax.xml.stream.XMLStreamReader;
public interface Echo {
String echo(String echo);
XMLStreamReader returnReader(String s);
}
EchoImpl.java
import javax.xml.stream.*;
import java.io.*;
public class EchoImpl implements Echo {
public String echo(String echo) {
return echo;
}
public XMLStreamReader returnReader(String s) {
System.out.println("returnReader called with param: " + s);
XMLStreamReader reader = null;
try {
XMLInputFactory factory =
XMLInputFactory.newInstance();
BufferedInputStream stream = new
BufferedInputStream(new
FileInputStream("/home/blast/xfire/testDir3/book.xml"));
reader = factory.createXMLStreamReader(stream);
System.out.println("after create XMLStreamReader");
} catch(Exception e) {
e.printStackTrace();
}
return reader;
}
}
