XML SQL Utility, Unicode

Question

Hi,
I have some questions to the XML-SQL-Utility:
1.) Is there a bug in the oracle.xml.sql.query class:
OracleXMLQuery qry = new OracleXMLQuery(conn,"select POSITION from DATAS");
qry.setRowTag("DROW");
OracleXMLDocGenDOM gdoc = new OracleXMLDocGenDOM();
qry.getXML(gdoc);
conn.close();
Document docin = gdoc.getXMLDocumentDOM();
NodeList rows = docin.getDocumentElement().getElementsByTagName("DROW");
// The Node "DROW" wasn't found.
// It work if I do it below
NodeList rows = docin.getDocumentElement().getElementsByTagName("ROW");
// It doesn't matter what is set in the "qry1.setRowTag("DROW");"
(I use the sun parser)
2.) I have a problem by insertXML(Document);
I will insert a Document with a structure as below in my database:
<?xml version="1.0" encoding="UTF-16"?>
<ROOTDOC>
<ROW>
<DOCUMENTREF>133-12224</DOCUMENTREF>
<TEXT>hello</TEXT>
</ROW>
<ROW>
<DOCUMENTREF>133-124</DOCUMENTREF>
<TEXT>world</TEXT>
</ROW>
</ROOTDOC>
XmlDocument sdoc = new XmlDocument();
Element rootDEl = sdoc.createElement("ROOTDOC");
sdoc. appendChild(rootDEl);
Element rowEl = sdoc.createElement("ROW");
Element docREl = sdoc.createElement("DOCUMENTREF");
docREl.appendChild(sdoc.createTextNode("133-12224"));
NodeList rows = sdoc.getDocumentElement().getElementsByTagName("ROW");
int size = rows.getLength();
System.out.println("SIZE: " size "\n");
// The size is null, what's wrong ?
OracleXMLSave save = new OracleXMLSave(conn, tabName);
int rowCount = save.insertXML(sdoc);
// It didn't insert something in my table !
3.) I save Unicode UTF-16 in my database with the XML SQL Utility:
<?xml version="1.0" encoding="UTF-16"?>
<ROOTDOC>
<ROW>
<TEXT>D$55DD</TEXT>
</ROW>
<ROW>
<TEXT>tt%zu||</TEXT>
If I read it whit the oracle.xml.sql.query, it is Unicode UTF-8:
OUTPUT IS:
<?xml version="1.0"?>
<ROOTDOC>
<ROW num="1">
<TEXT>D$55--</TEXT>
</ROW>
<ROW num="2">
<TEXT>tt%zu33</TEXT>
</ROW>
I want a output as the input (Unicode UTF-16).
Can anyone please advise on the problems.
Thanks

Answer 1

Hi H.Ozawa,
thanks for trying but non of the solution helped me, sorry.
Question 1:
I'll try it again like this:
OracleXMLQuery qry = new OracleXMLQuery(conn,"select POSITION from DATAS");
qry.setRowTag("DROW");
Document docin = qry.getXMLDOM();
conn.close();
NodeList rows = docin.getDocumentElement().getElementsByTagName("DROW");
// The Node "DROW" wasn't found.
Question 2:
<?xml version="1.0" encoding="UTF-16"?>
<ROOTDOC>
<ROW>
<DOCUMENTREF>133-12224</DOCUMENTREF>
<TEXT>hello</TEXT>
</ROW>
<ROW>
<DOCUMENTREF>133-124</DOCUMENTREF>
<TEXT>world</TEXT>
</ROW>
</ROOTDOC>
XmlDocument sdoc = new XmlDocument();
Element rootDEl = sdoc.createElement("ROOTDOC");
sdoc. appendChild(rootDEl);
Element rowEl = sdoc.createElement("ROW");
Element docREl = sdoc.createElement("DOCUMENTREF");
docREl.appendChild(sdoc.createTextNode("133-12224"));
Element docTEl = sdoc.createElement("TEXT");
docTEl.appendChild(sdoc.createTextNode("hello"));
An error message occur:
java.lang.reflect.InvocationTargetException: java.lang.IllegalAccessError: try to access class com/sun/xml/tree/ParentNode from class project/dbase/xmlwritedb at project.dbase.xmlwritedb.main(xmlwritedb.java:33)
at java.lang.reflect.Method.invoke(Native Method)

at com.borland.jbuilder.util.BootStrap.main(Unknown Source)
Question 3:
I try it like below but the output is "UTF-8" encoding
OracleXMLDocGenDOM gdoc = new OracleXMLDocGenDOM();
query.getXML(gdoc);
XMLDocument docin = (XMLDocument)gdoc.getXMLDocumentDOM();
docin.setEncoding("ISO-8859-1"); //docin.setEncoding("UTF-16");
NodeList rows = docin.getDocumentElement().getElementsByTagName("ROW");
Element row = (Element)rows.item( i );
NodeList elements = row.getElementsByTagName( "DOCUMENTREF" );
So you or someone have another idea to fix this problems.
Thanks
