[xmlvm-users] NeHeLesson4

[Jeremiah B. <jbl...@da...>]

Hi there,

I've been trying to run the NeHeLesson4 OpenGL example but I keep running
into exceptions. From Eclipse or the command line, I get the following
output, exception, and stack trace:

View: 320.0,480.0
Exception in thread "Thread-6" java.lang.NullPointerException
        at org.lwjgl.opengl.GL11.glViewport(GL11.java:3199)
        at org.xmlvm.iphone.gl.GL.glViewport(GL.java:625)
        at
org.xmlvm.iphone.demo.gl.nehelesson4.GLView.setupView(GLView.java:133)
        at
org.xmlvm.iphone.demo.gl.nehelesson4.GLView.drawView(GLView.java:155)
        at
org.xmlvm.iphone.demo.gl.nehelesson4.GLView$1.timerEvent(GLView.java:112)
        at org.xmlvm.iphone.NSTimer.timerTick(NSTimer.java:81)
        at org.xmlvm.iphone.NSTimer.access$1(NSTimer.java:80)
        at org.xmlvm.iphone.NSTimer$1.run(NSTimer.java:52)

Now, I did fix what appeared to be an error that prevented "setupView" from
being called, but even without it, I get very similar results:

View: 320.0,480.0
Exception in thread "Thread-6" java.lang.NullPointerException
        at org.lwjgl.opengl.GL11.glClear(GL11.java:586)
        at org.xmlvm.iphone.gl.GL.glClear(GL.java:594)

        at org.xmlvm.iphone.NSTimer.timerTick(NSTimer.java:81)
        at org.xmlvm.iphone.NSTimer.access$1(NSTimer.java:80)
        at org.xmlvm.iphone.NSTimer$1.run(NSTimer.java:52)

I've tried tracking down the problem but I'm not having any luck. Anyone
know how I can get this working? I'm in the process of porting some of my
code over to the iPhone but this has become a roadblock for me.

Thanks in advance!
