Having problems reading .wmo consistently, not sure whats wrong please help

[danielrhodea]

Hi,

As some of you may know I'm doing a wee bit of java programming with wow file types, in my adventures into the land of the .wmo file I have hit a wall, hard!!!

so far I have tested my java wmo class on the following adt files

WMO wmo = new WMO("C:\\wow\\World\\wmo\\Dungeon\\AZ_Subway\\Subway.wmo"); // 19 group files
wmo = new WMO("C:\\wow\\World\\wmo\\Azeroth\\Buildings\\Castle\\Castle01.wmo"); //2 group files
wmo = new WMO("C:\\wow\\World\\wmo\\Azeroth\\Buildings\\Castle\\Castle02.wmo"); //1 group file
wmo = new WMO("C:\\wow\\World\\wmo\\Azeroth\\Buildings\\Castle\\Castle03.wmo"); //1 group file
wmo = new WMO("C:\\wow\\World\\wmo\\Azeroth\\Buildings\\Stormwind\\Stormwind.wmo"); // 285 group files

stormwind is not reporting the correct number of group files, textures or anything, any ideas as to what is wrong, the code to my class is below

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

import java.lang.String;

public class WMO {
	//public WMOGroup *groups;
	public int nTextures, nGroups, nP, nLights, nModels, nDoodads, nDoodadSets, nX;
