NullPointerExceptionat.org.apache.transformer.TransformerImpl.run


> Ummm Im not sure abut this, but did the rendering actualy produce any
pages? The FOP output usualy logs for every page it produces too, in your
console output i cant see any of that.
Actually my JSP file could not produce any input, But that problem is solved
now by introducing the JSP file via URL class.

Thanks
