Spaces in subject line causing mail servlet to brake

Question

Hi,
I am working with cocoon, tomcat and xml/xsl/xsp. I have the mail servlet which works fine with html form always. However in the xml page if I put spaces in subject line or the text body, I am getting IOExcpetion. I
don't get any error if my subject and body text is one long word. Please help.
Here is the code for my XSP page
<?xml version="1.0"?>
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>
<?xml-stylesheet href="Station.xsl" type="text/xsl"?>
<xsp:page language="java" xmlns:xsp="http://www.apache.org/1999/XSP/Core"
xmlns:util="http://www.apache.org/1999/XSP/Util">
<xsp:structure>
<xsp:include>java.lang.*</xsp:include>
<xsp:include>java.util.*</xsp:include>
<xsp:include>java.io.*</xsp:include>
</xsp:structure>
<page>
<xsp:logic>
String From,sub,body;
From = request.getParameter("From");
sub = request.getParameter( "Subject");
body = request.getParameter("Body");
String x= "http://localhost:8080/kong/servlet/GSMailServlet?command=send&to=aj&from="+ From+"&subject=" sub "&text=" +body;
</xsp:logic>
<util:include-uri>
<util:href>
<xsp:expr>x</xsp:expr>
</util:href>
</util:include-uri>
</page>
</xsp:page>

Thanks for the suggestion. But When I tried using URLEncoder I got the output like this:
{http%3A%2F%2Flocalhost%3A8080%2Fkong%2Fservlet%2FGSMailServlet%3Fcommand%3Dsend%26to%3Daj%26from%3Daj%26subject%3Drest+gfdfg%26text%3Dggfd+gfg: java.net.MalformedURLException: no protocol: http%3A%2F%2Flocalhost%3A8080%2Fkong%2Fservlet%2FGSMailServlet%3Fcommand%3Dsend%26to%3Daj%26from%3Daj%26subject%3Drest+gfdfg%26text%3Dggfd+gfg}
Since Cocoon is doing the parsing I don't have the control over it. How do I solve this problem. Please help
