Oracle.xml.sql.dataset Package

Hi!
I am not able to find any documentation about this package
Any idea where to find one?
Thanks

Yes, of course I have. If you carefully see my first post, you will notice that I get an
'ORA-00904: invalid column name' error when I - in purpose - use an invalid Query, which means that communication with Oracle DB is fine. The problem appears when my Query does return some results. It's really confusing me...
Any other ideas?
thanks!

Oracle XSU class oracle.xml.sql.dataset.OracleXMLDataSetExtJdbc bug

Hi,
The oracle class oracle.xml.sql.dataset.OracleXMLDataSetExtJdbc needlessly casts the java.sql.Connection it receives in its constructor to oracle.jdbc.driver.OracleConnection.
This will work fine in most circumstances, but throws a class cast exception when a proxified connection is used such that the connection is a wrapper rather than an instance of OracleConnection.
I believe there would be absolutely no need for the oracle class to cast the connection to its derived form.
Please correct this problem in the XSU as soon as possible.
Thanks in advance,

Where is the oracle.xml.sql.query package?

Hi,
I have downloaded the xmlparser_v2_0_2_9.zip. I hoped I have everything to compile the example for retrieving XML document with an sql query. However, the jar file is missing the entire package oracle.xml.sql.query which contains for instance the crucial class OracleXMLQuery. Does anyone know where I could get this package - is it part of another download that I have to do, or can I buy it anywhere? Thanks for your help.

It's part of the XML SQL Utility for Java, avialable for download from http://technet.oracle.com/tech/xml

Problem in importing oracle.xml.sql.query.*

When i am importing this
import oracle.xml.sql.query.*;
it is giving me error that
"package oracle.xml.sql.query.* does not exist".
What Should i install or set .

[from XmlRpc-Java]
As a result, my XML
is contained in a String instead of an InputStream.
It is possible to convert a String to an InputStream using
StringBufferInputStream, but this class is deprecated in favor of
StringReader (as StringBufferInputStream does not properly convert
characters into bytes).
For the default HTTP transport, an InputStreamReader could be used to
wrap the InputStream before calling parse().
Ultimately, the InputStream is converted to an InputSource for use by
the SAX parser. InputSource will accept a Reader as well.
[from XmlRpc-Java]
There should be a way to go from "getXMLString()" to "parse(Reader)" also. In the meantime I'm stuck.

Murali,
Thank you, after I initialized Oracle's javavm
the errors disappeared.
The scripts were located under the javavm/install
directory.
Thanks again.

Oracle.xml.sql.OracleXMLSQLException when using OracleXMLQuery getXMLDOM()

Hi!
I am trying to reuse a code in JDeveloper to get XML from a query. I have copied the code from a method and created a new method with the copied code and changed it. The problem is that when I run the old code I now get following error:
Ett oförväntat fel har inträffat: Application: FND, Message Name: FND_GENERIC_MESSAGE.
Tokens: MESSAGE = oracle.xml.sql.OracleXMLSQLException: Det här objektet har stängts.
Vill du inte att objektet ska stängas automatiskt mellan anropen kan du granska metoden 'keepObjectOpen()'.;
This means in english something like:
An unexpected error accoured: Application: FND, Message Name: FND_GENERIC_MESSAGE = oracle.xml.sql.OracleXMLSQLException: This object is closed. If you don't want the object to close automatically between calls you can check method 'keepObjectOpen()';
the code I'm running is:
public String punchoutSomething()
throws Exception
StringBuffer sqlForXml =new StringBuffer("select pv.*"
+", cursor(select * from XXPOS_PUNCHOUT_TABLE2 c where c.vendor_id=pv.vendor_id) as contacts"
+" from XXPOS_PUNCHOUT_TABLE1 pv where vendor_id in (");
// add all ids
SuppSummVOImpl vendorView = getSuppSummVO();
Row row;
int punchoutCnt=0;
// vendorView.reset();
Row[] selectedRows = vendorView.getFilteredRows("SelectStatus","Y");
for(int i=0;i<selectedRows.length;i++)
if(punchoutCnt>0)
sqlForXml.append(",");
sqlForXml.append(((Number)selectedRows.getAttribute("VendorId")).toString());
punchoutCnt++;
if(punchoutCnt==0)
sqlForXml.append("-1"); // make sql valid, will not return rows
sqlForXml.append(")");
// System.out.println(sqlForXml); // DEBUG
OADBTransaction tx = (OADBTransaction)getOADBTransaction();
OracleXMLQuery xq = new OracleXMLQuery( tx.getJdbcConnection()
, sqlForXml.toString()
xq.setRaiseException(true); // in case of error raise an exception (default
// is to generate an error document
xq.setEncoding("UTF-8"); // not necessary?
xq.useLowerCaseTagNames();
xq.setRowsetTag("vendors");
xq.setRowTag("vendors_row");
//System.out.println(xq.getXMLString()); // DEBUG
XMLDocument suppl = (XMLDocument)xq.getXMLDOM();
XSLProcessor xslt = new XSLProcessor();
InputStream sheetStream = this.getClass().getResourceAsStream("mystylesheet.xsl");
if(sheetStream==null)
throw new Exception("Could not load stylesheet");
XSLStylesheet sheet = xslt.newXSLStylesheet(
sheetStream
StringWriter serialize = new StringWriter();
xslt.processXSL(sheet,suppl,new PrintWriter(serialize));
String returnXML = serialize.getBuffer().toString();
// System.out.println("X:"+returnXML); // DEBUG
sheetStream.close();
return returnXML;
===================
i've copied the same code into another method and only changed the sql-statment to be used and the stylesheet to use to transform the xml. Is something wrong with that?
Another question: if the xsl refers to a xsd but wihtout any path where should it be?
Thanks for the help,
Patricia

Actually, having looked at Metalink, seems that although this message may be accurate and correct,
it has been 'introduced' as part of the 9i JDBC driver.
So, I used the 8i JDBC driver I happened to have instead and that worked fine.

Oracle.xml.sql.OracleXMLSQLException: Expected name instead of .

Hi,
I'm using XDK in Tomcat to execute queries and get the XML result in the browser. I have written many queries but now I'm having problems in one of them.
The error output that I see in my browser is this one:
<ROOT>
<ERROR>
oracle.xml.sql.OracleXMLSQLException: Expected name instead of <.
</ERROR>
</ROOT>:
This error message is known as XML-20126 but it's not documented in the XML Developer's Kit Programmer's Guide, so I don't know what to do.
My XSQL query is the following:
<ROOT connection="xxxx_read" xmlns:xsql="urn:oracle-xsql">
<xsql:query>
SELECT XMLAGG(XMLELEMENT("NODE",
XMLELEMENT("name", b.nodename),
(SELECT XMLAGG(XMLELEMENT("SERVICE",
XMLATTRIBUTES(a.serviceabbr AS "type")
ORDER BY a.serviceabbr
FROM service a, serviceinstance c
WHERE c.isdeleted='N'
AND a.serviceid=c.serviceid
AND c.nodeid=b.nodeid
ORDER BY b.nodename
) AS "NODES"
FROM node b
WHERE b.isdeleted='N'
</xsql:query>
</ROOT>
That query executes fine in sqlplus, where I can see the XML result.
I think my problem could be related to the size of the XML output. In sqlplus, the output has around 38000 bytes size, which is nothing, so I don't really know why that should be a problem. Do you have any idea?
Thanks for your help,
David

So it seems there is a problem in fact:
XDB FUNCTION RESULTS ARE TRUNCATED WHEN USING XSQL
*** 02/25/04 08:28 am ***
Problem Description
There appears to be a limit on the content or characters that XSQL pages
handle when being passed data from XDB functions such as XMLAGG() and
XMLELEMENT().
If you have a xsql page of the form
< ?xml version="1.0"?>
< xsql:query xmlns:xsql="urn:oracle-xsql" connection="demo" >
select XMLAgg(XMLElement("Test", XMLAttributes(i.id as "Id_van_de_test",
i.name as "Name_van_de_test"))) as "Tests" from problem_xml i
< /xsql:query>
If the number of rows (or amount of data) in the table is low, the result
appears okay. However, if the data returned is large the data appears to
truncate giving xml parsing errors as if the xml returned is not well formed.
In the testcase provided, the error is as follows :-
Results from 10.1.0.2
< Line 2, Column 16354>: XML-20126: (Fatal Error) '< ' cannot appear in attribute value.
< Line 2, Column 16366>: XML-20190: (Fatal Error) Whitespace required.
< Line 2, Column 16366>: XML-20201: (Fatal Error) Expected name instead of 4.
< ?xml version = '1.0'?>
value.< /ERROR>
Results from 9.2.0.6
< Line 2, Column 16354>: XML-0126: (Fatal Error) '< ' cannot appear in attribute value.
< Line 2, Column 16368>: XML-0190: (Fatal Error) Whitespace required.
< Line 2, Column 16368>: XML-0201: (Fatal Error) Expected name instead of 3.
< Line 2, Column 16371>: XML-0122: (Fatal Error) '=' missing in attribute.
< Line 2, Column 16391>: XML-0190: (Fatal Error) Whitespace required.
< Line 2, Column 16396>: XML-0122: (Fatal Error) '=' missing in attribute.
< Line 2, Column 16397>: XML-0125: (Fatal Error) Attribute value should start with quote.
< ?xml version = '1.0'?>
value.< /ERROR>
And the workaround:
======================================================
The only workaround we have is to get the Document generated using
DBMS_XMLQUERY [with expanded entities].
_==Start===
create or replace procedure Query2XML(QueryString varchar2 default
'select col1 from xml_tab where r_id = ?') IS
XMLCtx number;
myXML clob;
myXMLLength number;
BEGIN
XMLCtx := DBMS_XMLQUERY.NEWCONTEXT(QueryString);
myXML := DBMS_XMLQUERY.GETXML(XMLCtx);
myXMLLength := DBMS_LOB.GETLENGTH(myXML);
DBMS_XMLQUERY.CLOSECONTEXT(XMLCtx);
END Query2XMLFile;
_==Start===
Currently, XDB uses a DOM based model for XSLT evaluation. It is not
possible to support disable-output-escaping constructs through this
evaluation. This might be supported in a future release when a different
model is implemented.
=============================================================

Oracle.xml.sql.OracleXMLSQLException:Cannot enable auto commit within JTS transaction

Hi All,
OracleXMLSave class in the Oracle XDK is being used to load XML data into an 8170 database. The Java code is running in IBM WebSphere with container-managed transactions. When JTA is enabled with the Merant JDBC driver for Oracle, we get the following error when the XML is loaded:
oracle.xml.sql.OracleXMLSQLException: Cannot enable auto commit within JTS
transaction
     at java.lang.Throwable.fillInStackTrace(Native Method)
     at oracle.xml.sql.dml.OracleXMLSave.saveXML(OracleXMLSave.java:2213)
     at oracle.xml.sql.dml.OracleXMLSave.insertXML(Compiled Code)
This suggests the OracleXMLSave class is not aware of the fact that it is now operating in a JTS transaction where control is managed elsewhere. i.e. should also not attempt to commit or rollback, as this is the responsibility of the container.
Is there a property which needs to set to prevent the above or does the XDK not work with J2EE (JTS) transactions?.
If you have any useful comments, let me know. Testing the above presents me with a number of problems so if this is easily explained , let me know.
Thanks,
Malcolm

Clearly , there does seem to be something a bit odd with the above stack.
<Bug:1917808> mentions OracleXMLSave in context of plsql equivalent : dbms_xmlsave . i.e dbms_xmlsave is a wrapper around OracleXMLSave class.
disabling autocommit on connection as follows should help:
conn = DriverManager.getConnection("connect string","scott","tiger");
conn.setAutoCommit(false);
to disble auto commit and see if this has an effect.
This issue might be <Bug:1497506>. If disabling autocommit does not work then it appears that it could be this issue .

JDeveloper Error ! oracle.xml.sql.OracleXMLSQLException: Cannot map Unicode

Hi All,
I have 2 identical table structures with different data in Oracle.
I am using following xsql and XSLT sheet to produce xml files with these tables. ( have to run twice xsql file by changing the Table names )
When I run the xsql file with Table1, it works fine, produced the xml file on the browser.
But when I run the xsql file with Table2, it gives following error message:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
Invalid at the top level of the document. Error processing resource 'http://192.10.1.14:8988/Workspace_ONIX-ONIX2-context-root/untitled1.xsql'. Line 1, Position 1

These two are my xsql and xslt files:

All comments are highly welcomed...
Thanks

Hi Deepak
Thanks for the post, but I am afraid that's not the issue with the error.
I changed both encoding to "UTF-8" still i get the problem.
I tried even without the XSLT sheet, still I have the problem..
- - - - xsql file ---
<?xml version = '1.0' ?>

<page xmlns:xsql="urn:oracle-xsql" connection="Connection1">

Any Comment ???

Oracle XSU: oracle.xml.sql.query.OracleXMLQuery is not recognized

Hi, there!
I've got a problem when tryed to use Oracle XSU (xml-sql utility to generate xml). My simple java application works fine using XSU. But when I created session stateless bean I've got an EJBException regarding this
line:
oracle.xml.sql.query.OracleXMLQuery qry = new oracle.xml.sql.query.OracleXMLQuery(conn, commandSQLStatement);
It doesn't recognize OracleXMLQuery class as I've got in dump. So my classpath includes original location of that utility and Oracle parser.
I really appreciate for any help.
Thanks.
strXML = qry.getXMLString();

Patricia,

Re: XML SQL Utility
You have to put xsu12.jar in the lib directory of the jdev.
xsu12.jar is in the lib directory of the XDK installation.
You can download XDK from
http://www.oracle.com/technology/tech/xml/xdk/software/prod/xdk_java.html
Just download the XDK kit, get the xsu12.jar from the lib directory and put in the lib directory of the jdev.

Oracle.xml.sql.query.OracleXMLQuery GetXML -withDTD

I am able to make it work using the XSU Command Line Utility, but I'm having a hard time trying to find out where the -withDTD flag goes inside my java program. Anyone know how to use the -withDTD option inside of a java program?
