Recommend Oracle XML Book?

Can anyone recommend an good Oracle XML book. I've checked out "Oracle XML Applications" by O'Reily and have heard good things about it. But it's 3 1/2 years old and doesn't discuss Oracle 9i features and no mention of XML Schema (didn't exist at that point I guess).
Thanks for any advice!!!

Hi,
Some of the books which provide good information about Oracle and XML (with a small description) are present at the following links:
1.http://www.xml-book.com/xml-and-oracle-books.html
'Building Oracle XML Applications' by Steve Muench is a good one
Huge documentation is present free on OTN at the following link:
1. http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/nav/docindex.htm#index-XML
Have a look at them. Various basic to advance samples are also present on OTN on XML at
1. http://otn.oracle.com/sample_code/tech/xml/xmldb/content.html
2. http://otn.oracle.com/sample_code/tech/xml/content.html
Check them.

Example 5-11 in Steve Muench's Oracle-XML book

Hi,
Anyone who studied the book Building Oracle XML Applications by Steve Muench (O'Reilly), could clarify this query. When I tried to execute Example 5-11:Test,Extract and Retrieve an XPath Expression Value (page 132) I get the following error:
PLS-00307: too many declarations of 'SELECTNODES' match this call (complete source code given at the end of this message).
Could you please explain why this error is occurring.
Best wishes,

I tried the wayback machine, but unfortunately, it doesn't cache the SWF files either :( I do have a copy of some (ok one) of Steve's old videos (the one that shows how to do a dropdown list in an editable table, back before it was easy to do), but unfortunately, none of the search ones.

Recommend a good XML book?

I am looking for a good XML book.
I found 'Building Oracle XML Applications' by Steve Muench at AMAZON, but its dated SEP 2000, and for Oracle 8i.
I'm using 9i...will this matter?
Suggestions please...
Thanks
Terry Stevens
UK

you can still get by with it and it is worth buying although it does need upgrading to 9i.
I have managed to produce XML files from it though and applied stylesheets to them so I would recommend it.

Building Oracle XML Application Book....

Has anyone purchased the 'Building Oracle XML Applications' book and do they have any opinions on it? Useful?

It it currently orderable, and is planned to ship by September 31st/October 1st, just in time for the Oracle OpenWorld conference.

first thanks for your reply,
i already figured that out and deployed it using 10.1.3.1 jars
my question
1) if it is a bug , how come it works fine with jdeveloper (
i would appreciate if you could provide any info about it.
2) i dont want to sound sarcastic , but 10.1.3.1 has of optimistic locking and the recommended solution i found was to use descriptor.getQueryManager().setUpdateCallCacheSize(0);
looks like 10.1.3.1 fixed one bug and introduced other one which was working fine earlier...
is there any other way of fixing optimistic locking issue other than using the
descriptor.getQueryManager().setUpdateCallCacheSize(0);
where i can find the latest/greatest (up to date patched version of toplink)
thanks again for your help

Bpel-108-UsingXQuery $publisher - oracle.xml.parser.v2.XMLElement@8b8e58

Hello,
I am using Oracle SOA Suite 11.1.1.4.0 While executing the XQuery example bpel-108-UsingXQuery I am facing the following problem/error.
The Xquery in the example is:
xquery version "1.0";
declare namespace ns0 = "http://example.com/bpel/books";
declare namespace ns1 = "http://samples.otn.com/xquerysample";
declare variable $category as node() external;
declare variable $publisher as xs:string external;
<bookReport>
for $b in //ns0:BOOKS/ns0:ITEM
where data($b/ns0:PUBLISHER) = $publisher
order by string-length($b/TITLE) return
<book>
<author> { data($b/ns0:AUTHOR) } </author>
<title> { data($b/ns0:TITLE) } </title>
<price>{ data(doc("pricelist.xml")/ns1:pricelist/ns1:product[1]/ns1:price) }</price>
<publisher>{ $publisher }</publisher>
{ $category }
</book>
</bookReport>
The variable $publisher, declared in 'declare variable $publisher as xs:string external' shall have the value 'Associated Press' as this has been assigned in the BPEL but it has in fact the value 'oracle.xml.parser.v2.XMLElement@8b8e58'.
The variable $category has the correct value.
What is here wrong or is it a bug in 11.1.1.4.0 in the oracle.xml.parser.v2.XMLElement class.

What a mess:
org.w3c.Element element = (org.w3c.Element) payload.get("payload");
private Document writeOraXMLtoDocument(org.w3c.Element payload) throws ParserConfigurationException, SAXException, IOException, TransformerException{
          ByteArrayInputStream inputStream = new ByteArrayInputStream(writeXMLToStream(new DOMSource(payload)).toByteArray());
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          DocumentBuilder builder =factory.newDocumentBuilder();
          return builder.parse(inputStream);
     private ByteArrayOutputStream writeXMLToStream(Source source) throws TransformerException {
ByteArrayOutputStream out = new ByteArrayOutputStream();
// Prepare the output file
Result result = new StreamResult(out);
// Write the DOM document to the file
TransformerFactory x = TransformerFactory.newInstance();
Transformer xformer = x.newTransformer();
xformer.transform(source, result);
return out;
Note, that you have to use the oracle transformer located in the xmlparserv2.jar
if it is not your default transformer , you have to set it at least for the above code by System.setProperty("javax.xml.transform.TransformerFactory","..classname...");

Does Oracle XML parser support scripts?

I've tried using scripts in my XSL which I parse with Oracle XML parser v2. If the function does not exist, I get error. But if the function exists, I get nothing at all on the output! Not even simple function that only returns a string.
I also have the same problems with <xsl:eval>.
Thank you for reading this,
David.

We fully support the XSLT 1.0 Recommendation.
<xsl:eval> and <xsl:script>
are not features of the XSLT standard.

Oracle Spatial book sample application

Hi all,
On Monday I received the Oracle Spatial book and I would like to post a topic about it. First of all I would like to congratulate the authors for their huge effort doing this excellent book. I think it will be very useful to the people that works with Spatial.
Next, my question is about the sample application showed in chapter 12 (SampleApplication.jsp). I run correctly mapviewer in my server and I can do the other examples, nevertheless when I want to start this application I recieve this error message about 'jdbc/spatial10g not found' in my web browser:

I am using Java 2 Runtime Environment version 1.4.2_02 and I think I have correctly configured the shared libraries in the oc4j server (sdoapi.jar, sdonm.jar, ojdbc14.jar, etc.). Anyway, I think I will be missing something but I don't know what.
I would be very grateful if somebody could help me.
Juan M.

Hi Juan
Thanks for purchasing our book, and thanks also for the kind words.
I think I know what that problem is.
The application uses the network API. That API needs a database connection for the initial loading of the network. The connection used is provided by OC4J. This is done in the following code lines in the SampleApplication.jsp:
// Get JDBC database connection
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("jdbc/"+dataSource.toLowerCase());
Connection conn = ds.getConnection();
// Load network
net = NetworkManager.readNetwork(conn, networkName);
In other words, for this to work, you need a datasource defined for OC4J, called "jdbc/spatial10g" (since dataSource is defined by default to be "SPATIAL10G".
To define the datasource, refer to chapter 11, page 499, at the bottom of the page. You need to add the following to your data-sources.xml config file ($OC4J_HOME/j2ee/home/config/data-sources.xml):
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="spatial10g"
location="jdbc/spatial10gCore"
xa-location="jdbc/xa/spatial10gXA"
ejb-location="jdbc/spatial10g"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="spatial"
password="spatial"
url="jdbc:oracle:thin:@localhost:1521:orcl101"
inactivity-timeout="30"
/>
(Adapt the url parameter to match your database definition)
Thanks for pointing out this problem. We will update the errata page (http://www.apress.com/book/errataDisplay.html?bID=315&sID=2374) with clearer instructions.

Oracle XML Schema documentation

Does anyone know if there are any good books, websites, etc ... with various examples on creating an xml schema that includes other schemas with different elements and how all schema objects are affected and linked when loading an xml instance file in the master schema? Most of the documentation I have found only discusses a schema with no includes and only one element. Thanks.

I believe that the desired default date format only applies for two functions:
"27.1 XML Date Formatting
Dates and timestamps in generated XML are now in the formats specified by XML Schema. See Oracle XML DB Developer's Guide, Chapter "Generating XML Data from the Database", *section "XMLELEMENT and XMLATTRIBUTES SQL Functions"*, subsection "Formatting of XML Dates and Timestamps"."
http://docs.oracle.com/cd/B19306_01/readmes.102/b14233/toc.htm#sthref85
Your quote from the docs ( http://docs.oracle.com/cd/B19306_01/appdev.102/b14259/xdb13gen.htm#sthref1506 ) applies to the SQL/XML standard functions, and apparently not to DBMS_XMLGEN (one of the Oracle Database-provided functions).
"It explains the SQL/XML standard functions and Oracle Database-provided functions and packages for generating XML data from relational content."
http://docs.oracle.com/cd/B19306_01/appdev.102/b14259/xdb13gen.htm#ADXDB1600
"If you otherwise need to produce a non-standard XML date or timestamp, use SQL function to_char"
http://docs.oracle.com/cd/B19306_01/appdev.102/b14259/xdb13gen.htm#sthref1506

Oracle8 pl/sql programmin by scott urman, oracle press book enough???

hi everybody, i have oracle8 pl/sql programmin by scott urman, oracle press book, which covers releases 7 through 8. is this book enough for me to prepare for the exam "introduction to oracle 1z0-001". please give your views. thanks..

I recommend you check the exact objetives here: http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_org_id=1000255&lang=ESA&p_exam_id=1Z0_001 and compare them with the objetives describe in the book. Currently I have 10 certifies and I have done the same always. I check the objetives in the Oracle web site and I study across Oracle Documentation. That is one of the best way to get a strong prepartion and it is shippper.

I just want to spend money from my pocket to buy books for my refrence,so looking what is everybody fav book.
or recommendation.
Like backup recovery
I want to buy one ,but
I am confused between sam alapati or robert freemanI agree with the recommendations made by P. Forstmann, although you could possibly start with Tom Kyte's book (you can read my review of that book on Amazon) and then come back to the Oracle Concepts Guide. Definitely, read and understand Tom Kyte's book before moving on to anything else. I also recommend the "Troubleshooting Oracle Performance" book (in my opiinion it is much better organized and well-rounded than the other performance tuning books that I have read... you can read my review on Amazon). Once you have a good understanding of Oracle SQL, you might also take a look at the "Pro Oracle SQL" book.
For backup and recovery, I found that (at least for the 10g version), Robert Freeman's book is very good for theory, however if something does not go as described in the book, you can be left digging through Google searches to determine how to progress. It also seemed that some of the information needed for the exercises was difficult to locate in the rest of the book. The "RMAN Recipes for Oracle Database 11g" is set up quite a bit differently from Robert Freeman's book. There are typically a couple of pages of theory at the start of each chapter, and then several practice exercises. If nothing else, the recipe format provides an insight into how RMAN works and what to do when it does not work. I found a handful of errors in the RMAN Recipes book, but the material seems to be very well organized, making it easy to progress through the book while testing/reproducing the various recipes. (I reviewed both of these books on Amazon also.)

Mark Logic vs. Oracle XML Database?

Hi,
I'm comparing Mark Logic vs Oracle XML database for a new project. All the data is well structured and validated XML data. Any comments, suggestions, personal experiences with either product will be extremely helpful.
Thanks in advance,
Dave

In 5+ years Oracle will still be the #1 database on the planet and people who have it on their resume will be employable.
In 5+ years Mark Logic will be out of business, a marginal player, or absorbed by either Oracle, IBM, or Microsoft. Unless you find some great romantic attraction to marginal technologies, can I recommend RPG II or ALGOL or Ingres, I would highly recommend Oracle.
Right now, at dice.com, there are 1,745 jobs listing Oracle and XML: There are 15 listing Mark Logic.
But heck the world economy is booming so why let that affect your decision. <g>

ClassNotFoundException: oracle.xml.parser.v2.DOMParser when deploying ear

I'm trying to deploy my disconnected-admin.ear (ADF faces web application) file. I kept getting ClassNotFoundError. In my ear file, I have a war file, I added the xmlparserv2.jar (which contains the class) to the war file's WEB-INF/lib folder. But I still get the same error. I also tried to copy the jar file to WLS_HOME/servers/lib folder, no luck there either. I have read a few other threads, and it's not recommended to add the jar file to the classpath. What else can I do?
Thanks,
Jing

Hi Sujay,
Add below line to your startWeblogic.sh script and restart the server. Also let me know if the issue is resolved.

Oracle XML Parser validation against XML Sxhema

Hi,
I am developing a program in C++ on Unix, that does parsing on an XML document. For parsing I am using "Oracle XML Parser" [using DOM API]. My question is, Can Oracle XML Parser validate xml document against an XML Schema file also? I have read in many tutorials that it can validate against DTD. Please clarify my question as early as possible?
Regards,
Raghuram.

Hi Kulkarni,
I think you are trying to retrieve the text of the parent element of book. For example if this is the xml element
<bookdetails>
<book>Harry Potter</book>
<author>JK Rowling</author>
<price>34.55</price>
</book>
</bookdetails>
You must be trying to retrieving the text of bookdetails.
Check XMLNode.getNodeName() to retrieve the name of the node.
To get 'Harry Potter' as output you need to traverse till book and then use XMLNode.getText()
You can check the 'getQuestions()' method in Survey Sample
to know how to tranverse to any element of an XML using Java.
The Survey Sample is located at
http://otn.oracle.com/sample_code/tech/xml/survey/content.html
Download the sample and unjar it. The location of Analyser.java is
SurveySample\code\Survey\src\oracle\otnsamples\survey\business\Analyser.java
Have a look at it.
Regards,
Anupama

XML book

Hi,
Could anyone please suggest a good book for learning XML?
Thanks.

I'm just learning XML myself and have worked through several XML books. I think that Building Oracle XML Applications by Steve Muench is easily the best on XML, especially when used with Oracle. Another good book is Java and XML by Brett McLaughlin.

Recommend Oracle XML Book?
