XSLT using XSU
I am trying to use the current Oracle XDK, in particular the XSU java
libraries to retrieve XML from a sql query. In order to generate the final
XML file I need to apply an XSLT. When using the OracleXMLQuery object to
set the XSLT I get the following run time exception:
java.lang.NoClassDefFoundError: oracle/sql/OPAQUE thrown from
oracle.xml.sql.query.OracleXMLQuery.setXSLT(OracleXMLQuery.java:779).
The libraries I included in my classpath are as follows:
xmlparserv2.jar
xchema.jar
xsu12.jar
oraclesxql.jar
classgen.jar
classes12.zip
nls_charset12.zip
jdk1.3
I'm not really sure what I am missing here. Any help would be greatly
appreciated.
BTW: everything works fine if I don't call the setXSLT method of the
OracleXMLQuery object
oracle/sql/OPAQUE class is in classes12.jar.
Please send your sample for me to test.
Thanks.

How to apply XSLT to XML file while importing XML data using XSU plsql API
I need to load XML file with nested repeating elements into Oracle tables and I am using XSU PLSQL API utility package dbms_xmlSave.insertXML. Can use XMLGen package also!!
I found out through documentation that I need to have XML file with ROWSET/ROW tags around the elements. As I have no control of XML file coming from external source, so I wish to apply XSLT to XML. I found setXSLT/setStylesheet procedures but it's not working as expected.
Can you help me with some sample code for the purpose.

Storing XML using XSU, object VIEW and INSTEAD OF trigger
Here is the point:
I've got 2 tables which are linked:
CREATE TABLE dept (
deptno NUMBER PRIMARY KEY,
deptname VARCHAR2(20)
CREATE TABLE emp (
empno NUMBER PRIMARY KEY,
empname VARCHAR2(20),
deptno NUMBER REFERENCES dept(deptno)
I've got the following message, which I want to insert in the tables using XSU (I already have a PL/SQL stored procedure which work perfectly for insertion into 1 table, using DBMS_XMLSave.insertXML or xmlgen.insertXML):
<DEPT>
<DEPTNO>10</DEPTNO>
<DEPTNAME>IT</DEPTNAME>
<EMP>
<EMPNO>1</EMPNO>
<EMPNAME>John</EMPNAME>
</EMP>
<EMP>
<EMPNO>1</EMPNO>
<EMPNAME>Phil</EMPNAME>
</EMP>
</DEPT>
So I've created the following object:
CREATE TYPE emp_t AS OBJECT
empno NUMBER,
empname VARCHAR2(20)
CREATE TYPE emplist_t AS TABLE OF emp_t;
CREATE TYPE dept_t AS OBJECT
deptno NUMBER,
deptname VARCHAR2(20),
emplist emplist_t
Now I understand that I should create an object VIEW and an INSTEAD OF trigger (That's what I read many times),
but I don't know how to structure the view and the trigger.
Could you help? (Example of a similar context, piece of code)
Thanks a lot
MarionHi John,
I have exactly the same issue as you experienced back in January. I have a complex data modelling requirement which requires the need to pivot rows into columns using ROW_NUMBER() and PARTITION clauses. To hide the complexity from the middle tier, I have created a database view and appropriate INSTEAD OF triggers and mapped my EO to the view. I have overriden the lock() method on the EO implementation class (to avoid ORA-02014) and would like to try the same solution you used with the pl/sql call to lock the record.
My question is, how did you manage the release of the lock if the transaction was not rolled back or committed by your application i.e. if the user closed the browser for instance.
In my naivity, I would like to think that the BC4J framework would release any locks for the database session when it found the servlet session to be terminated however my concern is that the lock would persist and cause complications.
Any assistance greatly appreciated (if you would be willing to supply your lock() method and pl/sql procedure logic I would be even more grateful!).
Many thanks,
Dave

Choosing particular columns using XSU PL/SQL API
Hi ya,
I have another query regarding XSU PL/SQL API please
If I dont want to choose all columns but choose particular columns
in my select clause,how shud I do this.??
I havent used XSU before,so please forgive my ignorance.
declare
queryCtx DBMS_XMLQuery.ctxType;
result CLOB;
begin
-- set the query context.
queryCtx := DBMS_XMLQuery.newContext('select CHOOSE CERTAIN COLS ONLY from <TABLE>');
result := DBMS_XMLQuery.getXML(queryCtx); -- get the result
DBMS_XMLQuery.closeContext(queryCtx); -- close the query handle;
end;
Can anyone tell me how to select particulat columnsor some one suggested(Mr Kishore) to use a view?
I dont want to use 'Select * from <Table>'
Help really appreciated.

Converting Oracle XML Query Result in Java String by using XSU
Hi,
I have a problem by converting Oracle XML Query Result in Java
String by using XSU. I use XSU for Java.
For example:
String datum=new OracleXMLQuery(conn,"Select max(ps.datum) from
preise ps where match='"+args[0]+"'");
String datum1=datum;
I become the following error:

Creating Object views using XSU PL/SQL.Please SEE.
Hi,
I am presently using XSU PL/SQL utility with Oracle 9i and using the
DBMS_XMLQuery.newContext(<My Select clause goes here>,and the
DBMS_XMLQuery.getXML()which generates an XML document.
My query is:
I have 2 tables (One master and the other detail table.).
Table : DI_Master
di_num
00001
Table: DI_Details
di_num di_act
00001 ABCD
00001 ANCF
00001 IOPP
Now the XML I'd like is :
<di_num>00001</di_num>
<di_act>
<val>ABCD</val>
<val>ANCF</val>
<val>IOPP</val>
</di_act>
Do I need to create object tables for this,insert data into object tables
and then read this table? It will become an extremely tedious process
I guess an OBJECT view can do what I want.Can anyone please tell me how
to write an object view for the 2 tables please and the get the output as
desired.?Supposing you have further
nesting of the tables.Then how will you go about doing that.You can have multiple levels of CURSOR expressions (see an example below, not a real-life example, but illustrates the point).

Also,isnt it a better option to create a VIEW of the
Select clause and pass a view to the select clause? At the end of the day, you could use whatever you feel comfortable with, provided that it produces your expected output and looks clean.

Using XSU to process multiple record sets
Have a design question about XML, Java and Oracle's XSU. This is a common task when importing external data that should be of general interest.
I have an incoming XML document with multiple records with a known DTD. Before the records can be inserted into the database, part of
the record must be used to do a lookup for a foreign key. The resulting foreign key is then combined with the other part of the
record to create a valid input record for the database.
My question is what's the most efficient way to do this? I assume the general approach must go something like:
begin
while (records in xml doc)
1. parse the incoming XML to extract the next record
2. if the lookup data change, do a lookup for this record using XSL
3. combine the resulting foreign key with the data to create
an insert query
4. add the insert query as a document fragment to a second XML document.
use XSU to insert the second XML doc with multiple records.
end
I've figured out how to do most of this, except for step 1 above: is there an easy way to extract the next record from an XML doc if I know the row nodes and the DTD? Or do I just have to traverse all the XML nodes until I hit my next row tag?
Appreciate any suggestions; this is a handy discussion list!

nullYes, typical behavior is that when you have multiple outputs it will create a one row IllumDoc to wrap them all together with OuputParameter=* (and the xml will be ignored unless it is the only output property or you've requested it by name).
How about just using "/Lighthammer/Illuminator?QueryTemplate=xxxx/yyyy&Content-Type=text/xml" or "/Lighthammer/Runner?Transaction=xxxx/yyyy&OutputParameter=OutputXML" which will both return your multi-rowset output?
I may be mistaken, but I believe the XacuteResponse was simplified to not include the Rowsets outer node because certain systems had problems digesting the layers, in fact you don't get the <Columns/> section either in the single Rowset.
Rick - any feedback to this SOAP simplification from Xacute? -

Creating Views using XSU PL/SQL API.Urgent please.
Folks,
I need some help in creating a View.
I am using XSU PL/SQL to generate an XML Document.
I have a table (SDI) with 2 cols CMPY_NUM and CPTY_BORG_NUM.
If the values in these 2 cols are equal then the xml
value to be returned is 'OURS' else return 'THEIRS'.
How do I Create this View please?
The XSU PL/SQL I am using to generate the XML is:
declare
queryCtx DBMS_XMLquery.ctxType;
xmlResult CLOB;
begin
queryCtx := DBMS_XMLQuery.newContext('select CMPY_NUM,CPTY_BORG_NUM from SDI');
xmlResult := DBMS_XMLQuery.getXML(queryCtx);
DBMS_XMLQuery.closeContext(queryCtx); -- you must close the query handle..
end;

Regards BerndHi Bernd,
here you can find an example how to use RFC lookup from an XSLT Mapping:

Is this what you're looking for?

Hello
1) I have trouble when using the Oracle XML SQL Ulitity (XSU) with Enterprise Java Beans (EJB).
This is due to that
oracle.xml.sql.OracleXMLSQLException extends RuntimeException
i.e. is interpreted by the EJB container as a system exception.
(java.sql.SQLException extends Exception)
2) Is there anywhere I can submit a change suggestion to the XSU developer team?

JSP XML file parsing XSLT using Xalan
Hi all
I have created an XML file "view_campaign.xml" using JSP as shown in a code below and i wanna know how i should proceed to parse the XML file and so i can display this XML as the XSLT file i created.
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%
// Identify a carriage return character for each output line
int iLf = 10;
char cLf = (char)iLf;
// Create a new empty binary file, which will content XML output
File outputFile = new File("C:\\WebContent\\view_campaigns.xml");
//outputFile.createNewFile();
FileWriter outfile = new FileWriter(outputFile);
// the header for XML file
outfile.write("<?xml version='1.0' encoding='ISO-8859-1'?>"+cLf);
try {
// Define connection string and make a connection to database
//DriverManager.registerDriver (new org.apache.derby.jdbc.ClientDriver());
Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/sample","app","app");
Statement stat = conn.createStatement();
// Create a recordset
ResultSet rset = stat.executeQuery("Select * From campagn");
// Expecting at least one record
if( !rset.next() ) {
throw new IllegalArgumentException("No data found for the campaigns table");
outfile.write("<campaigns>"+cLf);
outfile.write("<campaign>"+cLf);
outfile.write("<campaign_id>" + rset.getString("campagn_id") +"</campaign_id>"+cLf);
outfile.write("<campaign_name>" + rset.getString("campagn_name") +"</campaign_name>"+cLf);
outfile.write("<campaign_type>" + rset.getString("campagn_type") +"</campaign_type>"+cLf);
outfile.write("<client>" + rset.getString("client_name") +"</client>"+cLf);
outfile.write("<positions>" + rset.getString("positions_nbr") +"</positions>"+cLf);
outfile.write("<begin>" + rset.getString("campagn_beginning_date") +"</begin>"+cLf);
outfile.write("<close>" + rset.getString("campagn_ending_date") +"</close>"+cLf);
outfile.write("</campaign>"+cLf);
// Parse our recordset
// Parse our recordset
while(rset.next()) {
outfile.write("<campaign>"+cLf);
outfile.write("<campaign_id>" + rset.getString("campagn_id") +"</campaign_id>"+cLf);
outfile.write("<campaign_name>" + rset.getString("campagn_name") +"</campaign_name>"+cLf);

Try this code
JspWriter out = pageContext.getOut(); // Get JSP output writter
javax.xml.transform.TransformerFactory tFactory = javax.xml.transform.TransformerFactory.newInstance(); //Instantiate a TransformerFactory.
String realPath = "c:/applyXsl.xsl";
java.io.File file = new java.io.File(realPath); // crearte a file object for given XSL.
// Use the TransformerFactory to process the stylesheet Source and generate a Transformer.
javax.xml.transform.Transformer transformer = tFactory.newTransformer(new javax.xml.transform.stream.StreamSource(file));
java.io.StringReader inputStream = new java.io.StringReader("c:/xmlFile.xml"); // create an input stream for given XML doc
java.io.ByteArrayOutputStream obj = new java.io.ByteArrayOutputStream(); // Create an output stream for XSL applied XML doc.
// 3. Use the Transformer to transform an XML Source and send the output to a Result object.
transformer.transform(new javax.xml.transform.stream.StreamSource(inputStream), new javax.xml.transform.stream.StreamResult(obj));
String outputString = obj.toString(); // get the XSL applied applied XML document for print
out.println(outputString); // print the XSL applied XML in to JSP.
however you need xercesImpl.jar and xml-apis.jar files to run this program.
