XMLDataSet and Dynamic XML using JSP

Question

I am trying to use the XMLDataSet function to call a jsp page
instead of an xml file. The jsp page fetches records out of a db
and creates xml to return to the spry function. Nothing seems to be
returned, and blank spry data region on page.
If i supply a xml file to the function it works correctly.
I adapted the ASP/PHP samples from XMLExport demo. Code as
follows:- If i run 2nd jsp directly, the browser shows the xml as
expected.
--- TEST.JSP ---
<script type="text/javascript">
Spry.Data.Region.debug=true;
var dsPeople = new Spry.Data.XMLDataSet("transtoxml.jsp",
"company/person");
</script>
--- transtoxml.jsp ---
<%@ page language="java"
import="java.sql.*, java.io.*, java.util.*,
com.Ostermiller.util.*"
errorPage="" %>
<%@ include file="globals.jsp" %>
<%
String SQL="";
Statement sTransaction;
ResultSet rTransaction;
try
Class.forName(className);
con =
java.sql.DriverManager.getConnection(connectionURL,userName,password);
}catch(Exception e){
out.print(e.toString());
out.print("Error connecting to database " + connectionURL);
SQL ="SELECT ";
SQL+="[ID], ";
SQL+="[DocumentNo]";
SQL+="FROM TRX_TRANSACTION_MAPPING";
sTransaction = con.createStatement();
try {
rTransaction = sTransaction.executeQuery(SQL);
response.setContentType("text/xml");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("pragma","no-cache");
%>
<?xml version='1.0' encoding='iso-8859-1'?>
<company>
<% while(rTransaction.next()) { %>
<person>
<id><%=(rTransaction.getString("ID"))%></id>
</person>
<% } %>
</company>
<%
response.flushBuffer();
sTransaction.close();
} catch (SQLException e) {
out.print(e);
%>

Answer 1

This is the xml output the jsp gives when run directly:- Cut
n pasted from browser. There does appear to be an error, because
the spry:state="error" div is being displayed. If i paste the
following into a file all is ok, any ideas anyone.
