XML Parsing in Java Stored Proc--Oracle XML Support Installation?
I am working with a third party product that is having difficulty running a java stored proc that is parsing a supplied XML file. The proc basically looks like:
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
InputStream is = getXMLAsInputStream(xml);
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse( is );
... parse the document ....
catch (FactoryConfigurationError e) {
// unable to get a document builder factory
We are running on 9.2.0.6, HP-UX 64-bit. At first, when we would attempt to run the proc, a database hang would occur; now after attempting to install using loadjava jars for xerces2.6: ORA-29532: Java call terminated by uncaught Java exception:
javax.xml.parsers.FactoryConfigurationError: Provider
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found)
The vendor says that the errors we are getting when running are not due to any dependency on xerces or jre1.4, and that we need to "install Oracle XML support", but I'm not certain what this means (I cannot find any documentation on what to install). I believe that there are jars that need to be loaded into the database to support the XML parsing, as jre1.3 does not include built-in XML support, and Oracle 9.2.0.6 uses jre1.3.
So...does anyone have any thoughts as to how to resolve the missing references? Is there a way to "install Oracle XML support", or is it to install the necessary jars?
Thanks,
Candi
Candi,
The following resources should be of help:
Oracle9i Database Release 2 (9.2) Documentation Library
In particular, check out the following:
Java Developer's Guide
Java Stored Procedures Developer's Guide
XML API Reference - XDK and Oracle XML DB
XML Database Developer's Guide - Oracle XML DB
XML Developer's Kits Guide - XDK
If that doesn't help, then try the following:
OracleJVM and Java Stored Procedures
XML Technology Center
Good Luck,
Avi.

Parse XML in a java stored proc
I am trying to parse an xml document in a java stored procedure. Just following my nose, I have developed a stored proc that works fine in development (outside the database using JRE 1.4.1) using the Xerces 2.5 parser. But, after having transferred the xerces xercesImpl.jar, xmlapis.jar, and my implementation class into oracle using loadjava when I call my stored proc the code throws an exception trying to build the document with an error like:
NoClassDef exception org.apache.xerces.jaxp.DocumentFactoryBuilderImpl
My Code looks like this:
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
InputStream is = getXMLAsInputStream(xml);
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse( is );
... parse the document ....
catch (FactoryConfigurationError e) {
// unable to get a document builder factory
The exception caught is a FactoryConfigurtionError.
I'm not particularly attached to xerces, I'm really just looking for a way to parse XML inside my java stored proc, so any help to solve my problem, or an alternative suggestion will be greatly appreciated.
thanks
DaleI looked again and sure enough the xerces implementation classes were missing. I had run a .cmd file containing these two lines, but it looks like only the first one ran...
loadjava -u ncc/xyz@usd -v -r M:\Database\JavaGeocode\Xerces2_5_0\xml-apis.jar
loadjava -u ncc/xyz@usd -v -r M:\Database\JavaGeocode\Xerces2_5_0\xercesImpl.jar
Now I've got everything working fine with Xerces!

Java Stored Proc - Oracle DBMS Output
The title pretty much says it all. I have a Java Stored Procedure and I need to direct output preferably to DBMS output from within the Java code. (This is a proof of concept and the managers want to see out put from it so they "know" it's working.)
System.out.println seems to disappear (though why that is the case I have no idea) in spite of the fact that the samples all show the use of System.err to generate error messages.
I'm not married to the idea of DBMS output, but it's an easy place to have the output for debugging purposes.
Comments suggestions and ideas most welcome.
Regards,
PThis might get you going in the right direction:
DBMS_JAVA
Gives you the ability to modify the behavior of the Aurora Java Virtual Machine (JVM) in Oracle. You can enable output (meaning that System.out.println will act like DBMS_OUTPUT.PUT_LINE), set compiler and debugger options, and more.
You can try this link and look for SET_OUTPUT

i am using
org.xml.sax.helpers.DefaultHandler api for parsing xml file ,while parsing i am getting exception sometimes ,
i am using code below to parse the element and then store it to vectore
parser truncate the charaacters sometimes like parsing string
" NJ-HealthCare " i am getting only " NJ-HealthCare " and remaing characters are added in new element
public void characters(char ch[], int start, int length) {
try{
ElementVal="";
System.out.println(" start "+start+" ength :: "+length);
String ElementVal = new String(ch,start,length);
v.addElement( ElementVal );
}catch(Exception ex){
System.out.println("Exception in vector::"+ex);
System.out.println(""+ex.getMessage());
ex.printStackTrace();
}This is an FAQ in the XML forum. The characters() method is not required to give you an entire text node all at once. The parser is free to split up the text node and call characters() several times if it likes. Your program will have to account for that possibility.

Problem with java stored procs.
Is there a restriction on accessing XML documents from Java stored procs?
I have a Java program to parse XML document and return a string. If I run this program as a stand alone, the program runs fine.
I loaded the oracle xmlparser.jar into ORACLE8i db sucessfully (used -resolve option). Then I loaded my .class file with -verbose and -resolve option and I did not get any erros. I created function which return string. When I ran the function, I did not get any value bacmk.
Can I use System.out.println in java programs in ORACLE8i. If I can where can I see the output when the program runs? I not waht other mehtods I can use to debug the program running in ORACLE8i JVM.
Thank YouHello again,
I read the documentation of 9i and found some hints about different TCP/IP socket handling of 9i and a standard JVM.
There are some parts that give hints but I couldn't find a sample code to show how to handle the differences.
Could anyone tell me how to handle the differences or give some links to sample code?
Thanks

Nls support with oracle xml parser in java
I'm using The JAXP interface to manipulate xml with xsl. the implementation that I use is Oracle xml parser.
My xml contains a lot of hebrew chars, and in the result stream each char translated into 5-6 chars, which makes the result to be 5-6 times bigger than it suppose to be, and harder for me to debug my application.
The client's browser shows the results well.
How can I make the transformator to transform the hebrew chars to hebrew char istead of longer and not readable string ?Oracle XML Team wrote:

ORACLE XML PARSER FOR JAVA FOR AIX
Hi people!
I'm looking for the Oracle XML Parser for Java 9.0.2.0.0C, my 9iAS is BI Installation 9.0.2.3, where can I get it? In the Downloads Section there is only the version for 10g, and the existing versions for 9i are not for AIX (my OS is AIX 5.2L).
Thanks.Thanks for your help, I navigate through this link and, even it shows a table where appears the release for AIX (9.2.0.6.0), when I get to http://www.oracle.com/technology/tech/xml/xdk/software/prod/utilsoft_java.htm
it shows me only downloads for Sun, Linux and HP-UX, but not for AIX.
Has the version for AIX being deprecated or something like that? -
Hello
I am getting java.lang.ClassCastException: oracle.xml.parser.v2.XMLText cannot be cast to org.w3c.dom.Element error. This code is in java which is present in java embedding.
The SOA is parsing the xml in java code using oracle.xml.parser.v2 . This wont be a problem if the SOA uses default w3c DOM parser. How do i force SOA to use w3c DOM parser.
Is there any thing i can do with class loading?
Kindly help.

select * from emp. It displayed the full table.
Then i set the class path for XDK,XMLparserv2,oracle JDBC driver and then ran the same query on dos prompt(that is front end command line for java in my case).
The following is the line i tried to execute on the command prompt

Upgrading Oracle XML Parser for Java v9.0.4 with Oracle Applications 11i
Guys, I applied ATG.PF.H.RUP4. In postinstall steps it is mentioned,Upgrading Oracle XML Parser for Java v9.0.4 with Oracle Applications 11i(doc-271148.1)
which says after applying patch 4038964 do the following--
AUTOCONFIG ENABLED APPLICATIONS ENVIRONMENT
If the Oracle E-Business Suite configuration files are maintained using the AutoConfig infrastructure, proceed with the following:
1. Run the AutoConfig utility.
2. Go to [JAVA_TOP].
3. Run the unzip -l appsborg2.zip | grep 9.0.4 command. If there is a file named as .xdkjava_version_9.0.4.0.0_production, which indicates that XML Parser for Java v9.0.4 is installed correctly as part of appsborg2.zip. Otherwise, run ADAdmin to regenerate the appsborg2.zip file.
4. Restart the application tier server processes such that the new version of Oracle XML Parser for Java will take effect.
but actually the patch is already applied- 4038964. How do i verify if i need to do these steps or not.
The xmlparserv2-904.zip file is already there in wrapper.classpath. of jserv.properties, forms.properties. So i think i dont need to do these steps.unzip -l appsborg2.zip | grep 9.0.4
