WebRowSet properties for Oracle 10g XML

Question

//I am writing data into a database
//Clob field then useing a WebRowSet writing
//it as XML to the clob
ResultSet rs = statement.executeQuery();
WebRowSet webRowSet = new WebRowSetImpl();
webRowSet.setCommand(sql);
webRowSet.populate(rs);
// First add the base entry to the database
ReportResultDao rrDao = new ReportResultDao();
ReportResultVo rrVo = new ReportResultVo();
rrVo.setProcessRequestId(processRequest.getRequestId());
rrVo.setDescription("Report_UserListByRealmSecurityCode");
int reportResultId = rrDao.addReportResult(rrVo);
// Next read that entry back so that the CLOB can be inserted
rrVo = rrDao.getReportResult(reportResultId);
Clob results = rrVo.getResult();
// write the clob value
Writer clobWriter = new BufferedWriter(results.setCharacterStream(0L));
webRowSet.writeXml(clobWriter);
clobWriter.close();
//I then read the XMl but get an error
Clob clob = reportResult.getResult();
clobCharacterStream = new BufferedReader(clob.getCharacterStream());
webRowSet = new WebRowSetImpl();
webRowSet.readXml(clobCharacterStream);
// This is the error
     : XML-20220: (Fatal Error) Invalid InputSource.
// I validated the XML using an XML Validator tool
//and found the following flaws
<datasource><null /></datasource>
<table-name><null /></table-name>
<url><null /></url>
// I removed the <null /> string and re-validate
// and success with
<datasource></datasource>
<table-name></table-name>
<url></url>
//Now how do I do that so the row set produces the
//same thing???
//I tried the following
// before writing the xml I set the following
webRowSet.setDataSourceName(" "); // there was no setdataSource method
webRowSet.setTableName(" ");
webRowSet.setUrl(" ");
// and before reading I set
webRowSet.setDataSourceName(" "); // there was no setdataSource method
webRowSet.setTableName(" ");
webRowSet.setUrl(" ");
// Still I got error
     : XML-20220: (Fatal Error) Invalid InputSource.
// But this time when I validated I just got an reported flaw on
<datasource><null /></datasource>
// The url and table-name both accepted " "
Can anyone help me with this issue?

The decsion to prevent access to the filesystem was taken as part of the general process of hardening the database for security reasons.
I use XSL with includes in the following form without any problems
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:n1="http://www.w3.org/2001/XMLSchema" xmlns:r="http://xmlns.oracle.com/xdb/XDBResource.xsd" xmlns:xfiles="http://xmlns.oracle.com/xfiles" xmlns:xr="http://xmlns.oracle.com/xdb/XDBResource.xsd">
     <xsl:output version="1.0" encoding="utf-8" omit-xml-declaration="no" indent="no" media-type="text/html" method="html"/>
     <xsl:include href="/cabo/XSL/XFilesCommon.xsl"/>
     <xsl:variable name="reverseSort">
