OracleXMLQuery

I am using a set of PL/SQL packages to maintain business logic. The PL/SQL packages return nested tables to Java Beans which interact with JSP's. I am having problems in Java when I get the oracle.sql.ARRAY and get the ResultSet to create an OracleXMLQuery object (OracleXMLQuery(Connection,ResultSet).
The Oracle ARRAY returns an Oracle ArrayDataResultSet which is not a java.sql.ResultSet and does not support OracleXMLQuery's call to getMetaData() when attempting to parse the ResultSet into XML. Any ideas?
NOTE: We have chosen not to pass (SQL Strings) queries to the OracleXMLQuery object to improve performance on the backend. (Reduce unnecessary parsing, reuse cursors and allow bind variables to be used.)
Thanks-
Jon

How are you first getting a hold of the ARRAY? selecting it from an object table or object view ? In other words, at some part of your program do you SELECT the ARRAY column or attribute into a program language variable of type oracle.sql.ARRAY or are you programmatically constructing it?

Decode function in OracleXMLQuery

selectStr = "SELECT DECODE(email,null,'',email), FROM mytable WHERE user_id=\'" + search_id + "\'";
using this select statement in conjunction with OracleXMLQuery produces the following exception.
oracle.xml.sql.OracleXMLSQLException: Character ')' is not allowed in an XML tag name.
any hints why ')' ist not supported?
null

solved, renaming the decode function helps
like
selectStr = "SELECT DECODE(email,null,'',email) email, FROM mytable WHERE user_id=\'" + search_id + "\'";

Null or Empty string in OracleXMLQuery - XDK

Dear all,
I am using OracleXMLQuery of XDK to construct an XML File from the contents retrieved from the database.
I see that for columns which have null values or empty string, the corresponding tag is not displayed in the XML File. Instead, even for columns that have empty string I need the tags to be displayed in the following format <tag1> </tag1>
Kindly let me know if this is possible.

Ya, I will try that. That seems to be a good idea. Thanks for the response.
I have one more query. Whenever we add a new column to any table in Oracle, the column name is stored in Upper case. So when we generate XML File from the database, all the tags are either in upper case (or we can use qry.useLowerCaseTagNames() to retrieve the tag names in lower case). But the XSD contains tag names in mixed case. So when validating the XML Document against an XSD, it throws a validation error.
Is there any way I can avoid this?

How to generate PDF output from OracleXMLQuery

I want to generate a PDF out put from XML by using JSP. For this i writen jsp and xsl. My jsp code works fine if i include html formated xsl and it displays as a text when i pass pdf formated xls.
Here i am providing my jsp code.
I don't want to use XSQL, please provide me information ASAP.
<%@ page import = "java.sql.*,oracle.xml.sql.query.OracleXMLQuery" %>

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.

Converting ResultSet to XML by OracleXMLQuery

Hello,
I'm newbie in XML and I have following problem:
I'm using OracleXMLQuery to convert ResultSet from oracle db to XML document. I'm using getXMLDOM()(from oracle package) to convert this OracleXMLQuery into DOM representation. I can extract node names but all values of the nodes are null's (if I convert the document to string and put it on the screen, the values are connect). Here's my code:
QracleXMLQuery qry;
ResultSet rset = (ResultSet)stmt.getObject(1);
qry = new OracleXMLQuery(conn,rset);
      qry.setRaiseNoRowsException(true);
      qry.setRaiseException(true);
      qry.keepObjectOpen(true);
      qry.useNullAttributeIndicator(true);
Document d=(Document)qry.getXMLDOM();
        //---to this point all seems to be correct
        // -OracleXMLQuery object stores correct xml document and
        // qry.getXMLDOM() return good Document object
NodeList nl=d.getElementsByTagName("some_tag_name");
for(int i=0;i<nl.getLength();i++){
     Node temp=nl.item(i);
     System.out.println(temp.getNodeValue()); //null's
     System.out.println(temp.getNodeName()); //correct name of the string
     }Maybe i'm missing something, as I wrote earlier I'm newbie in XML - I would be very grateful for any help. Thanks in advance!

Thanks for your reply - it really helped. I have another problem,maybe some of you may help me: I have two DOM documents and I want to join then like this
Documant a:
<?xml version = '1.0'?>
<ROWSET>
     <ROW num="1">
        <attr1>sometext1</attr1>
        <attr2>sometext2</attr2>
        <attr3>sometext3</attr3>
     </ROW>
     <ROW num="2">
     </ROW>
     <ROW num="3">
     </ROW>
</ROWSET>Doc b
<?xml version = '1.0'?>
<attrib>
<ROW num="1">
     <atr1>sometext1</atr1>
     <text>othertext1</text>
</ROW>
<ROW num="2">
     <atr2>sometext2</atr2>
     <text>othertext1</text>
</ROW>
<ROW num="3">
     <atr3>sometext3</atr3>
     <text>othertext1</text>
   </ROW>
</attrib>Now I want to insert the whole <attrib>...</attrib> section from document b as a node to document a in for example <ROW num="1">...</ROW> section. I've tried to create Node element form document b (<attrib></attrib>) and use insertBefore() method on Node <ROW num="1"></ROW> but I have a nullpointer exception - well it probably wasn't good idea.I hope my description is clear, I vould be happy for any advice. Thanks in advance

OracleXMLQuery not fetching ALL rows

Problem:
======
For example, if there are 10 rows in the Table, sometimes the XMLQuery sees less than 10 rows. We wrote a small test program with a JDBC query for select count(*) from Table, which always shows 10. So nothing wrong with Connection/Statement settings. They all use DEFAULT settings (READ_COMMITTED, TYPE_FORWARS_ONLY).
Why does n't XMLQuery see all rows available from the Query?
Software Version:
============
Oracle 10.1.0.5
XDK: Oracle XDK 10g
JAVA 5
My program:
=========
Connection connection = dataSource.getConnection();
Statement stmt = connection.createStatement(); <-- We tried with TYPE_SCROLL*. Still not working.
ResultSet rs = stmt.executeQuery("select * from MyTable);
//1. Query the database with the OracleXMLQuery. Result will be in XML format.
OracleXMLQuery query = new OracleXMLQuery(connection, rs);
query.keepObjectOpen(true);
query.setMaxRows(1); //We don't want to build huge XML DOM for all rows.
while (rs.next()) { <--- Ideally it should iterate 10 times XMLDocument xmlDoc = (XMLDocument) query.getXMLDOM();
System.out.println(xmlDoc);
if (query.getNumRowsProcessed() > 0) {
//Do something here
Thanks.

Using OracleXMLQuery with Oracle 9i

Sample code example -
OracleXMLQuery xmlData = new OracleXMLQuery(conn, sqlQuery);
String xmlString = xmlData.getXMLString();
PrintWriter xmlFile.print(xmlString);
I am able to connect to the database and print out the XML file. I'm querying an object that has a table embedded and everything was printing out okay in 8i, but now it 9i the string data fields in the embedded table are printing out in hexadecimal format. I've been to Sun's web site and in the forum discussions other developers are having the same problems without any know solution.
Has anyone here came up with a fix?

I thought that imp, with full=Y option will import everything into this empty dB, no matter There are not any schemes and users that were in the original dB...
Your understanding is 100% correct, but the question is, how did you take the export? Because, if you have taken full export, you haven't hit this problem. Could you tell us how did you made export?

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.

Anyone know how to use the -withDTD option inside of a java program?

[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.

There should be a way to go from "getXMLString()" to "parse(Reader)" also. In the meantime I'm stuck.

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.

Are you using JDBC/ODBC to access Oracle,

If Oracle, are you using Oracle8 object
