Remote URL with encoded variables with FOP Servlet whitespace problem.

Hello there,

I have modified the FOP Servlet to allow it to read in an url as input instead of a local file. The urls are php files which take variables passed in a get line to generate the correct XML and XSL-FO files. Everything works perfectly if there is no whitespace or %20 in the url. I.E.

http://127.0.0.1:8080/fop/fop?xsl=http://domain.loc/xsldoc.php%3Ftemplate_id=60&xml=http://fireantxtt.loc/xmldoc.php%3Ftemplate_id=60%26GRP0=accessuser%7Csean%26GRP1=short_name%7CABBTurbidityMeter&remot

It pulls in the correct info and generates the pdf. As soon as one of the variables contains a %20, the servlet returns this error:

http://127.0.0.1:8080/fop/fop?xsl=http://domain.loc/xsldoc.php%3Ftemplate_id=60&xml=http://fireantxtt.loc/xmldoc.php%3Ftemplate_id=60%26GRP0=accessuser%7Csean%26GRP1=short_name%7CABB%20Turbidity%20Meter&remot

javax.servlet.ServletException: Server returned HTTP response code: 400 for URL: http://fireantxtt.loc/xmldoc.php?template_id=60&GRP0=accessuser|sean&GRP1=short_name|ABB Turbidity Meter
FopServlet.doGet(Unknown Source)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

I understand that it is most likely java automatically converting %20 back to whitespace before retreiving the url. Is there a way to keep urlencoding throughout. Below is my modified code which is called if &remot is appended to the url. I realize it's ugly bulky code but this is my first time using java.

                URL url = new URL(xmlParam);
                URLConnection urlconn = url.openConnection();

                  FileOutputStream foxml = new FileOutputStream ("temp.xml");
                  ByteArrayOutputStream tempxml = new ByteArrayOutputStream () ;
                  int lengthxml = urlconn.getContentLength();
                  InputStream isxml = urlconn.getInputStream();
                  int chxml ;
                  while ( (chxml = isxml.read())>0)
                  {
                      tempxml.write (chxml);
                  }
                  tempxml.writeTo(foxml);
                  isxml.close();

                URL url2 = new URL(xslParam);
                URLConnection urlconn2 = url2.openConnection();


                  FileOutputStream foxsl = new FileOutputStream ("temp.xsl");
                  ByteArrayOutputStream tempxsl = new ByteArrayOutputStream () ;
                  int lengthxsl = urlconn2.getContentLength();
                  InputStream isxsl = urlconn2.getInputStream();
                  int chxsl ;
                  while ( (chxsl = isxsl.read())>0)
                  {
                        tempxsl.write (chxsl);
                  }
                  tempxsl.writeTo(foxsl);
                  isxsl.close();

                XSLTInputHandler input =
                  new XSLTInputHandler(new File("temp.xml"),
                                       new File("temp.xsl"));
                renderXML(input, response);
