help with jsp include tag

Hi
I am having a problem with the jsp include tag on my page
I am trying to include a graph generated by cgi onto a jsp page . To render the graph I would have to pass the page paramters but when I run the page
all i get is a blank screen .
when I take the offending tags out the page loads normally
Can anyone tell me what I am doing wrong ?
many thanks

the offending code is as follows

<% Calendar today = Calendar.getInstance();
int day = today.DAY_OF_MONTH;
int month = today.MONTH;
int year = today.YEAR;
%>
<jsp:include page= &quot;<jsparam name=&quot;dd&quot; value=&quot;<%=day%>&quot; />
<jsparam name=&quot;mm&quot; value=&quot;<%=month%>&quot; />
<jsparam name=&quot;yyyy&quot; value=&quot;<%=year%>&quot; />
<jsparam name=&quot;zoom&quot; value=&quot;2&quot; />
<jsparam name=&quot;yscale1&quot; value=&quot;100&quot; />
<jsparam name=&quot;yscale2&quot; value=&quot;500&quot; />
<jsparam name=&quot;yscale3&quot; value=&quot;0&quot; />
<jsparam name=&quot;yscale4&quot; value=&quot;0&quot; />
<jsparam name=&quot;yscale5&quot; value=&quot;0&quot; />
<jsparam name=&quot;start&quot; value=&quot;96&quot; />
<jsparam name=&quot;end&quot; value=&quot;216&quot; />
<jsparam name=&quot;days&quot; value=&quot;62&quot; />
<jsparam name=&quot;opt&quot; value=&quot;2629600&quot; />
<jsparam name=&quot;type&quot; value=&quot;16&quot; />
<jsparam name=&quot;ports&quot; value=&quot;185%20&quot; />
</jsp:include>
