Invalid InputSource Error using XML Parser V2

Question

I'm using the following code to read xml from
a clob field in an Oracle database.
try
// Parse xsl and xml documents
parser = new DOMParser();
parser.setPreserveWhitespace(true);
Statement sqlSel=conn.createStatement();
ResultSet xmlDet=sqlSel.executeQuery("SELECT * FROM USER_XML WHERE IHC_USER_ID='123456789'");
if (xmlDet.next())
CLOB xmlCLOB= ((OracleResultSet)xmlDet).getCLOB(2);
int index=0;
Reader clobStream=xmlCLOB.getCharacterStream();
parser.parse(clobStream);
Everything seems to work fine, and I can
create a String from the stream which contains the entire XML document. However, if I try to do the above and parse the Stream, or alternatively parse the String resulting from the stream, I get the following Error:
nvalid InputSource.
void oracle.xml.parser.v2.XMLError.flushErrors()
void oracle.xml.parser.v2.XMLError.error(int, int, java.lang.String, java.lang.String, java.lang.String, int, java.lang.Exception, int, boolean)
void oracle.xml.parser.v2.XMLError.error(oracle.xml.parser.v2.XMLReader, java.lang.String, int, java.lang.Exception, int, boolean)
void oracle.xml.parser.v2.XMLReader.pushXMLReader(org.xml.sax.InputSource)
void oracle.xml.parser.v2.XMLParser.parse(java.lang.String)
void xmlquerydb.testParse()
void xmlquerydb.main(java.lang.String[])
Any ideas what could cause this?

Answer 1

I'm quite sure the xml documents are valid.
At present, I'm just using booklist.xml,
which comes as an example with the XML SQL
utility. The problem is not really with the
parsing (If I convert the xml into a url then it parses fine).
My real problem is pulling the document out
of a CLOB field. Regardless of what I pass to the parser( a string or a stream), or which xml its parsing, I still get the Invalid inputsource error.
