[jdom-interest] Memory Errors in JDOM

[Smith, Jonathan]

Funy thing. I had a DOM program writing a 8MB file out and then I changed it to JDOM and I am getting the following error

C:\data\projects\XMLRead>jdom > jdom_out.xml
Exception in thread "main" java.lang.OutOfMemoryError

C:\data\projects\XMLRead>

Below is a sample of the code I am using

import netscape.ldap.*;
import netscape.ldap.util.*;
import netscape.ldap.client.*;

import org.jdom.*;
import org.jdom.output.*;


import java.util.*;
import java.io.*;
