XML DTD questions

[Meichun Li <lim@metalab.unc.edu>]

Hi, 

I wrote a java class which is using DOM to process data in a XML file  
into  database.  The java class workes well without DTD added to the XML. 
But I  got errors when I add this line-
<!DOCTYPE omf SYSTEM "OMF.dtd">

The errors are as follows. These are result from invalid dtd file or 
somthing else?

Could anyone help me out? Thanks a lot!
