How to run dynamically created jnlp?

Question

Hi,
I'm learning how to run a dynamic jnlp file create by a cgi program.
I have a jnlp file, which can be executed by the in the
HTML file. Then my experiment is to write a perl script to print
exactly the same content as the jnlp file, and then the href is
re-directed to the cgi. But Then I got an error complaining
the first line:
Bad header = <?xml version="1.0+" .... ?>Is there anything else I should add in the header?
Thanks.

To be more specific about my question, here is the perl script I used
to generate the jnlp file. What should I add to it?
Thanks.
#!/usr/bin/perl
use CGI;
## Read parameters
$query = new CGI;
$SecID    = $query->param("SECID");
$PlayName = $query->param("PlayName");
$PlayFile = $query->param("PlayFile");
$PlayFrom = $query->param("PlayFrom");
$PlayTo   = $query->param("PlayTo");
$CodeBase = $query->param("CodeBase");
# Generating jnlp
print "Content-Type: application/x-java-jnlp-file \n";
#print '<%page contentType="application/x-java-jnlp-file" %>'."\n";
print '<?xml version="1.0" encoding="utf-8"?>'."\n";
print "<jnlp spec=\"1.0+\"  codebase= \"$CodeBase\" />\n";
print "  <information> \n";
print "    <title> $PlayName </title> ";
print "    <vender>  </vender> \n";
