I am getting the following error when I hit this servlet
ERROR:
XML Parsing Error: no element found
Location: http://url/LeagueStandings
Line Number 1, Column 1:

SERVLET CODE:
           RStoXML rsxml = new RStoXML(results, "ResultSet", "Result");
            //create the XML from recordset
            Document jDOMDoc = rsxml.build();            
            results.close();
            XMLOutputter outputter = new XMLOutputter() ;
            StringWriter writer = new StringWriter() ;
            outputter.output( jDOMDoc, writer );
            writer.close() ;
            //respond with output stream
            rep.setContentType("text/xml");
            rep.getOutputStream();
 logger.debug(outputter.outputString(jDOMDoc));

The XML returned in the debug message is below.
XML:
<?xml version="1.0" encoding="UTF-8"?>
<ResultSet>
    <Result>
         <ROUNDS>3</ROUNDS>
         <USERNAME>testuser</USERNAME>
         <BIRDIES>2</BIRDIES>
         <PARS>13</PARS>
         <BOGIES>28</BOGIES>
         <DOUBLES>11</DOUBLES>
         <GH>10</GH>
        <FH>10</FH>
        <PUTTS>108</PUTTS>
        <SCORES>264</SCORES>
    </Result>
</ResultSet>

You can only use the outputtter once probably. Try just


rep.setContentType("text/xml");
outputter.output( jDOMDoc, rep.getWriter() );

I put the  logger.debug(outputter.outputString(jDOMDoc)); in there after I experienced the error to check the XML, but I just took it out just in case and I am still getting the error.

The section of the Servlet:

            RStoXML rsxml = new RStoXML(results, "ResultSet", "Result");
            //create the XML from recordset
            Document jDOMDoc = rsxml.build();            
            results.close();
            XMLOutputter outputter = new XMLOutputter() ;
            StringWriter writer = new StringWriter() ;
            outputter.output( jDOMDoc, writer );
            writer.close() ;
            //respond with output stream
            rep.setContentType("text/xml");
            rep.getOutputStream();

You're not writing anything to the output stream. Try

rep.getWriter().println(writer.toString());

Thanks, that got rid of the error. Below is the final snippet of code.

            RStoXML rsxml = new RStoXML(results, "ResultSet", "Result");
            //create the XML from recordset
            Document jDOMDoc = rsxml.build();            
            results.close();
            XMLOutputter outputter = new XMLOutputter() ;
            StringWriter writer = new StringWriter() ;
            outputter.output( jDOMDoc, writer );
            writer.close() ;
            //respond with output stream
            rep.setContentType("text/xml");
            rep.getWriter().println(writer.toString());

:-) If you don't need 'writer' again you should be able to do

RStoXML rsxml = new RStoXML(results, "ResultSet", "Result");
//create the XML from recordset
Document jDOMDoc = rsxml.build();            
results.close();
XMLOutputter outputter = new XMLOutputter() ;
rep.setContentType("text/xml");
outputter.output( jDOMDoc, rep.getWriter() );
