Applying an XSLT against results from XSU in Java Stored Procedure

Question

Is there an easy way to have a Java Stored Procedure apply an XSLT against the results of an OracleXMLQuery? The only examples I can find are with regular Java code outside the database.
I'm running 9.2.0.2 on Windows 2000 Server.

This is what I use:
(I have table called params where I have stored encodinf, XSL, and stuff like that)
DOMParser parser;
XMLDocument xml, xsldoc, outXML;
URL xslURL;
URL xmlURL;
Connection conn = getConnection();
Statement stmt = conn.createStatement();
ResultSet rset= stmt.executeQuery("select xsl_varchar2,encoding,version,host,port,host_path,usrnm,passwrd from params");
rset.next();
String strXSL=rset.getString(1); //This is XSL transformation
String strEncoding=rset.getString(2);
String strVersion=rset.getString(3);
rset.close();
stmt.close();
parser = new DOMParser();
parser.setPreserveWhitespace(true);
StringReader rXSL= new StringReader(strXSL);
xslURL=createURL("test");
parser.parse(rXSL);
xsldoc=parser.getDocument();
OracleXMLQuery qry = new OracleXMLQuery(conn, "select * from somewhere");
xml=(XMLDocument) qry.getXMLDOM();
// instantiate a stylesheet
XSLStylesheet xsl = new XSLStylesheet(xsldoc, xslURL);
XSLProcessor processor = new XSLProcessor();
// display any warnings that may occur
processor.showWarnings(true);
processor.setErrorStream(System.err);
// Process XSL
DocumentFragment result = processor.processXSL(xsl, xml);
// create an output document to hold the result
outXML = new XMLDocument();
outXML.setVersion(strVersion);
outXML.setEncoding(strEncoding);
outXML.appendChild(result);
outXML is your XML.
