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:

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..

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.

value.< /ERROR>

< Line 2, Column 16368>: XML-0201: (Fatal Error) Expected name instead of 3.

< 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 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()

// add all ids

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());

sheetStream

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,

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.

Your inputs may be of high use for me as well.
I have similar requirement. I have to execute the following sql query

XSU error oracle.xml.sql.OracleXMLSQLException: Conversion to String failed

qry.close();
I get the following Error:

Any ideas on how I can resolve this issue? Your help would be appreciated.
Thanks!

Okay, it looks like the problem has something to do with the TIMESTAMP data type in tables.
oracle.xml.sql.query.OracleXMLQuery can't seem to handle tables with the TIMESTAMP data type.
this code ran fine on my machine :
import oracle.jdbc.driver.*;
import oracle.xml.sql.query.OracleXMLQuery;
import java.lang.*;
import java.sql.*;
public class testXMLSQL {
public static void main(String[] args) {
try {
// Create the connection
System.out.println("before getConnection ");
Connection conn = getConnection("scott","tiger");
System.out.println("after getConnection ");
// Create the query class
OracleXMLQuery qry = new OracleXMLQuery(conn, "SELECT * FROM EMP");
System.out.println("after OracleXMLQuery object created ");
// Get the XML string
String str = qry.getXMLString();
// Print the XML output
System.out.println("The XML output is:\n"+str);
// Always close the query to get rid of any resources..
qry.close();
} catch(SQLException e) {
System.out.println(e.toString());
// Get the connection given the user name and password.!
private static Connection getConnection(String username,
String password)
throws SQLException
// register the JDBC driver..
DriverManager.registerDriver(new
oracle.jdbc.driver.OracleDriver());
// Create the connection using the OCI8 driver
Connection conn =
DriverManager.getConnection(
"jdbc:oracle:thin:@<server_name>:1521:<sid>",
username,password);
return conn;
Then I created another table :
create table emp_test as select * from emp;
added a timestamp to it :
alter table emp_test add (time timestamp(6));
and filled it with timestamp information :
update emp_test set time = timestamp'2005-09-22 09:26:50.124';
ran the same code but changed the SQL to :
"SELECT * FROM EMP_TEST"
and got the error message :
The XML output is:
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: Conversion to String failed</ERROR>
looks like bug in OracleXMLQuery object??

Oracle XML SQL utility, error oracle.xml.sql.OracleXMLSQLException:....

I am using Oracle XML SQL utility to generate some XML using CURSOR

WHERE PROJECT.PROJ_ID = ISSUES.PROJ_ID )
as ISSUES_DATA

This query works fine when I create a direct connection using Oracle JDBC
thin driver. But when I execute same thing using a connection from a
Weblogic connection pool (which uses exactly the same Oracle JDBC thin
driver, classes12.zip), I get following error-
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: cursorGetMetaData: this method

Oracle 8.1.5 on Sun Solaris
Oracle JDBC thin Classes12.zip (from Oracle 8.1.6)
Oracle XML SQL utility XSU12_ver1_2_1
Does anyone have any idea what is going on. Please help.
Thanks.

Thanks for your reply.
Here is what I am doing:
I have connection pool defined in welogic.properties file
weblogic.jdbc.connectionPool.oraclePool=\
url=jdbc:oracle:thin:@192.168.2.251:1521:orcl,\
driver=oracle.jdbc.driver.OracleDriver,\
loginDelaySecs=1,\
initialCapacity=1,\
maxCapacity=15,\
capacityIncrement=1,\
allowShrinking=true,\
shrinkPeriodMins=5,\
refreshMinutes=5,\
testTable=,\
props=user=someuser;password=somepasswd
weblogic.allow.reserve.weblogic.jdbc.connectionPool.oraclePool=everyone
weblogic.jdbc.TXDataSource.orclDataSource=oraclePool
Then I have a DBConnection class which gets connection from the pool
following is some code from DBConnection class
private Connection con = null;
private DataSource ds = null;
private String providerURL;
private String dataSource;
private String contextFactory;
private IpmsProps ipmsProp = null;
public Connection getConnection() {
if ( con == null ) {
try {
ipmsProp = IpmsProps.getInstance();
providerURL = ipmsProp.getProviderURL();
dataSource = ipmsProp.getDataSource();
contextFactory = ipmsProp.getContextFactory();
Properties p = new Properties();
p.put(javax.naming.Context.PROVIDER_URL, providerURL);
p.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,
contextFactory);
Context ctx = new InitialContext(p);
Context ctx = new InitialContext();
ds = (DataSource) ctx.lookup(dataSource);
con = ds.getConnection();
} catch (Exception e) {
System.out.println("Error While creating connection! " +
e.toString());
} // catch
I Hope you will be able to provide me some work around.
Thank you very much for the help.

Hi. It's probably because you're calling some Oracle-specific method,passing it
a pool JDBC object, and though the Oracle methos signature says it will
take a generic java.sql.XXX object, it really is going to assume the thingis
an Oracle class, and fails when it tries to cast it to such.
Depending on how you're getting your pool connection, I may have aworkaround.

driver, classes12.zip), I get following error-
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: cursorGetMetaData: thismethod

'OracleXMLDataSetExtJdbc' instead.</ERROR>
Following are the details about my environment:
Weblogic5.1 on Windows NT 4.0
Oracle 8.1.5 on Sun Solaris
Oracle JDBC thin Classes12.zip (from Oracle 8.1.6)
Oracle XML SQL utility XSU12_ver1_2_1
Does anyone have any idea what is going on. Please help.

Unable to load Oracle XML SQL utility

The following error appears for each java
class, when we attempt to load Oracle XML sql
utility into Oracle using the oraclexmlsqlload
script:
E.g.
Error while resolving class OracleXMLStore
ORA-00904: invalid column name
Does anyone know why we would receive this error?
Platform: Hp-UX 11.0
Oracle Version: 8.1.5.0
Background information:
The database was original created with the
compatible=8.0.5 set in the init.ora file, and
the creatation of java classes failed due to this,
so switched compatible to 8.1.0. Now after we
we adjusted the compatible setting and restarted
database, we started to receive the errors as
described above.

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

Java.lang.NoClassDefFoundError: oracle/xml/sql/query/OracleXMLQuery

Hello, all.
I get this error message:
java.lang.NoClassDefFoundError: oracle/xml/sql/query/OracleXMLQuery
at oracle.xml.xsql.actions.XSQLQueryHandler.handleAction(Compiled Code) ...
when trying to view an xsql page with the jswdk 1.0.1 web server. (I have no problems when using Web-to-go)
Classpath includes:
C:\jdk1.1.8\lib\classes.zip;
C:\xsql\lib\oraclexsql.jar;
C:\xsql\lib\xmlparserv2.jar;
C:\xsql\lib\xsu111.jar;
C:\xsql\lib\classes111.zip;
C:\xsql\lib;
What could be the problem?

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Steven Muench ([email protected]):
Only thing I can think of is that maybe your server classpath is getting too long. I recall one of the Java Web Server releases having a classpath length limit that caused strange errors like this because that .jar files you thought were on your classpath were getting their path names truncated so the Java VM cannot find the JAR's.
Try putting xsu111.jar earlier in the list of JAR's and/or try shortening the classpath (perhaps by using SUBST'd drive letters or softlinks on Unix to shorten the path names).<HR></BLOCKQUOTE>
Putting the xsu11.jar file towards the start of the path did not help.
I have rewriten the entire bat file that creates the CLASSPATH and starts the server and things now seem to work. There must have been some error in the original bat file, that I just couldn't see.
Anyway - I thank you for your help.

Medrec pointbase orace RDBMS migration (Cannot set auto-commit mode)

For proof-of-concept purposes, I'm trying to install the MEDREC application on an Oracle database. I've migrated the schema using the demo.ddl found on the base install image. However, when I update the JDBC connect string to point to the oracle rdbms, I rec'v the message below. Has anyone discovered a workaround?
After the jdbc connect string is updated to point to Oracle, I see the app server connected successfully to the database.

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,
Did you go through the link
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'm trying to create a dtd for each table in my schema. I've created a java program that loops through the user_tables and I am then trying to create the DTD with oracle.xml.sql.query.OracleXMLQuery -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?
Thanks

[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.
