A DESCRIPTION OF THE PROBLEM :
The JNLP specification version 1.5 suggests this DOCTYPE declaration for JNLP files:

<!DOCTYPE jnlp-discriptor PUBLIC
  "-//Sun Microsystems, Inc//DTD JNLP Discriptor 1.1"//EN">

This doctype has three errors:

1. The root element of a JNLP File is not <jnlp-discriptor>, but <jnlp>.
2. The word "Descriptor" is spelled incorrectly
3. The JNLP spec is at version 1.5, not 1.1

A correct DOCTYPE for JNLP files would be:

<!DOCTYPE jnlp PUBLIC
  "-//Sun Microsystems, Inc//DTD JNLP Descriptor 1.5"//EN">
