ORA-29534 when loading Java XML Parser

Hi. I'm trying to install the Java and PL/SQL parsers into an 8i database, following the instructions in Steve Muench's O'Reilly book.
It looks like loadjava is loading the classes, but when it tries to resolve them I get the ORA-29534 error for each class. We're running 8.1.5 on the database, and the parser is 2.0.10 (I think - I downloaded it from OTN today, and I'm installing the Java parser from the Java XDK not the PL/SQL XDK).
Any help is appreciated.
Thanks in advance,

That's 2.0.2.10 not 2.0.10

Java XML Parser:Null Pointer exception in EntityReader

I got NullPointer Exception when trying to parse a XML file which
is pointed by a net URL, (say "http://www..."). The code causing
problem is like:
parser.parse(new URL("http://www.../demo.xml"));
the exception I got is:
java.lang.NullPointerException
java.lang.NullPointerException
at oracle.xml.parser.EntityReader.initXMLInput(Compiled
Code)
at
oracle.xml.parser.EntityReader.<init>(EntityReader.java:64)
at oracle.xml.parser.XMLParser.parse(XMLParser.java:245)
at DemoXML.main(DemoXML.java:47)
The very same code works fine with a simple local file URL and we
also know that the URL exists in correct in XML format because we
can open the URL with IE5.
Another question - where can we get the source for the Java XML
Parser.

This bug has already been reported and will be fixed in our next

ORA-00911:invalid character when loading an XML doc to the XMLType column

We have followed this code snippet: http://www.oracle.com/technology/sample_code/tech/java/codesnippet/xmldb/Example_Code.html#createclob
using the CLOB object to load an XML Document which has more 4000 characters to the XMLType column, we got the error -- ORA-00911:invalid character.
Sound likes an encoding issue? any suggestions would be appreciated.
BTW, we're able to use the TopLink's mapping -- Direct-to-Field to insert an XML String (<4000 characters) to the XMLType column.
Thanks!

Try removing the semi-colon at the end of your statement. That is the cause of ORA-911 with DBMS_SQL.PARSE and EXECUTE IMMEDIATE, I don't see why ADO should be any different.

Encount Ora-29534 when loadjava xmlparserv2.jar

I encounted ora-29534 error message when I tried to load xml pl/sql parser using the following command:
% loadjava -user scott/tiger -r -v xmlparserv2.jar
Environment: Oracle8.1.5
windows nt sp4
jdk1.1.8
What causes this problem and how to resolve it?
Thanks!
Allen

Got the problem sorted out. Apparently it was because I had Oracle 8.1.5 which used Java 1.1.7, whereas the version of xmlparserv2.jar I had was compiled using a more recent version of Java.
Migrated to Oracle 8.1.7, and that solved the problem.

'Enter Binds' popup screen when loading Java source in database

Hello,
when loading a Java source in the database with the command:
create or replace and compile java source named ...
a popup window comes up whichs prompts for bind variables this and null. In version 3.1.05 of SQL Developer this window does not pop up, with version 3.1.07 it does.
Is this a known bug?
Best regards,
Joop

Hello Gary,
I have made this test program:
create or replace and compile java source named "nl.cb.plsqlParser.attributeValue.TestloadOra" as
package nl.cb.plsqlParser.attributeValue;
public class TestloadOra {
     String b;
     * @return the b
     public String getB() {
          return b;
public void dumpAttribute() {
System.out.println("Parse run ID: " + (this.getB() == null ?
"null" : this.getB()));
This comes up with a screen with title 'Enter Binds', this is a different screen as you mentioned 'Enter Substitution variable'. In the 'Enter binds' screen there is a prompt for 'this'.
Can you explain how to load Java with a menu option? From the File navigator there is no Load Java menu option.
Best regards,
Joop

Java XML Parser v2 xpath problem

I have a lot of trouble using the xpath functionality. I want to get the name of different elements. I'm using some xpath expressions which in my opinion should work (see http://www.w3.org/TR/xpath ), but they don't. I'm calling XMLNode.selectSingleNode.
For example :
/*/name()
name(/*[1])
name(/*)
name()
I've tried those with Saxon and they do work. Using the Oracle implementation an exception is thrown on most expressions. So what's wrong here?
Bye,
Jan

Consider this example
--- Test.java -----
import java.io.*;
import javax.xml.transform.sax.SAXSource;
import net.sf.saxon.sxpath.*;
import oracle.xml.parser.v2.*;
import org.w3c.dom.*;
import org.xml.sax.InputSource;
public class Test
public Test() {
try {
DOMParser domParser = new DOMParser();
domParser.parse(new FileReader("test.xml"));
XMLDocument document = domParser.getDocument();
InputSource is = new InputSource(new File("test.xml").toURL().toString());
SAXSource source = new SAXSource(is);
testXPathOracle(document,"count(//*)");
testXPathOracle(document,"name(/*)");
testXPathOracle(document,"name(/root)");
testXPathOracle(document,"/*/name()");
testXPathSaxon(source,"count(//*)");
testXPathSaxon(source,"name(/*)");
testXPathSaxon(source,"name(/root)");
testXPathSaxon(source,"/*/name()");
} catch(Exception e) {
System.out.println(e.getMessage());
public void testXPathOracle(XMLNode context, String xpath) {
try {
Node node = context.selectSingleNode(xpath);
System.out.println(node.getNodeValue());
} catch(Exception e) {
System.out.println(e.getMessage());
public void testXPathSaxon(SAXSource source, String xpath) {
try {
XPathEvaluator xpe = new XPathEvaluator();
XPathExpression exp = xpe.createExpression(xpath);
Object object = exp.evaluateSingle(source);
System.out.println(object);
} catch(Exception e) {
System.out.println(e.getMessage());
public static void main(String[] args) {
Test test = new Test();
--- test.xml -----
<root>
<element/>
</root>
Result is on my computer:
Unknown expression at EOF: (count(//*))[1].
Unknown expression at EOF: (name(/*))[1].
Unknown expression at EOF: (name(/root))[1].
Error in expression: '(/*/name())[1]'.
2
root
root
root
I think the xpath expressions are valid. So what's wrong?

Libs to link when using C XML parser

Can anyone explain why this work:
LIB =-lcore8 -lnls8 -lcore8 -lnls8 -lcore8
but not this:
LIB =-lcore8 -lnls8
It causes link errors.
They are the libraries distributed with the Oracle C XML parser.

Thank you for your answer! It is good to know how it works particularly because we have had a lot of problems with this parser.

Thanks in advance
Regards

I suggest you create a DTD or a XSD file to validate your existing XML document, because it's easier that i looks, and will help in future changes.
If you want to do it in Java code, you can always store each line of the XML file in some form (like a class) in a List, and the each time you read a line, you compare with everything on the list.
But don't go that way, make a XSD file

The first problem about this document is that it contains a space at the very first position whereas <?xml... must appear at the very beginning of a document. I think this was the cause of the parsing fault.
Also you have a dash before the root element of the document, which is illegal.

Hello all,
Almost a year ago, we built some custom webdynpro iviews. Until now everything works fine, but the customer has requested some minor changes .
So I connected to the dev server and loaded the track we had created for this project. The problem is that when we create a project from the DTR, in order to edit it, we get a load of errors, which were ofcourse not occurring when we compiled the project .
For example, this is an error in my Custom Controller "ZHRCOS_P0002_CONTR"
The code was automatically generated by the system when it was created, so if I try to change anything I get the message "This Code is Derived, do you really want to change it?"
inside the code there is the function
infoRecords = GCIContext.createModelNode("Records", true, CMICardinality.MANY, CMICardinality.ZERO_TO_ONE, true, ... etc .
There I get the message
"CMICardinality.MANY cannot be resolved"
I would think that some necessary packages were not loaded during the "Create project" procedure, although I loaded all the dependencies .
But, what I actually see, is that the class <CMICardinality> exists, only that instead of having the constant <MANY>, it has the constant <CARDINALITY_MANY> .
This is something I cannot understand, because the Dynpros were compiled almost one year ago and they are still working fine. Why do I get those problems ?

Thank you both, but I have already tried these approaches. I also tried with other projects and I have the same problem .
Also I noticed that the visual editor seems to have a problem, but I do not know if it is connected to the above .
"Unhandled event loop exception"
I have changed my NWDS to 7.2, but I don't think that the studio version would have any impact on the building of the webdynpro.

Firefox on Linux crashes when loading java script web page while running on Windows works fine

Hello all,
well in my effort in writting php I frequently use phpanywhere.com
The site loads successfully in both Windows and Linux setup (fully up-dated). However, when I press on .php file so to begin editing the Linux installed Firefox crashes and closes down every time (also when using different preference under JacaScript menu). Windows setup seems to have no problem at all.
This has been checked in three different PC with Ubuntu Maveric installed on them. In all these cases Firefox crashes.
Any possible ideas on that one?

I have the same problem. I've never been able to identify when it started. Once firefox crashes, mpd, if it was playing, becomes unresponsive. The only way to get a flash site working again is to reboot my computer.
I uninstalled flash: I'm not going to put up with that kind of behaviour. Now I watch youtube videos on other people's computers --you know how they say "You've GOT to see this movie!". And if I really need to see that one specific video, there's youtube-dl.
Unfortunately gnash doesn't work on youtube for me.

Java XML parsing with Xerces in Eclipse using Oxygen problem

Hey everybody,
Got me a stickler of a prob here and i'm hoping sum one out there will be able to help. I am trying to parse XML files into JDom objects so i can use them in the rest of my project with ease, but i'm having trouble parsing anything wihtout getting these errors
Error: URI = /filelocat/personal-schema.xml", Line = "3", : Document root element "personnel", must match DOCTYPE root "null".
Error: URI = /filelocat/personal-schema.xml", Line = "3", : Document is invalid: no grammar found.
Error: URI = /filelocat/personal-schema.xml", Line = "3", : cvc-complex-type.3.2.2: Attribute 'xsi:noNamespaceSchemaLocation' is not allowed to appear in element 'personnel'.
Error: URI = /filelocat/personal-schema.xml", Line = "3", : cvc-complex-type.3.2.2: Attribute 'xsi:noNamespaceSchemaLocation' is not allowed to appear in element 'personnel'.
The are the files are ones that come in Oxygens samples folder so they should be correct. The code is as follows
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          factory.setValidating(true);
SchemaFactory sFact = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
Schema schema = sFact.newSchema(schemaFile);
factory.setSchema(schema);
DocumentBuilder dommer = factory.newDocumentBuilder();
Document doco = dommer.parse(xmlFile.getAbsolutePath());None of these errors appears to be fatal, i can still use the doco object and extract the information i require, but i want to understand where the errors are coming from. There must be a parser setting or sumthing i've missed somewhere.
Can anyone help?
Any ideas/surgestions/critique welcome.
Tom

When we are parsing this xml: "<CustomerInfo><VCID/>77888</CustomerInfo>".
See comments in following code.
Element docEle = d.getDocumentElement(); // Returns "CustomerInfo" element node.
NodeList childNodes2 = docEle.getChildNodes(); // Returns two nodes: <VCID/> element node and 77888 text node.
Node item4 = childNodes2.item( 0 ); // First node (element node) of the "CustomerInfo" tag. <VCID/>
Node item5 = childNodes2.item( 1 ); // Second node (text node) of the "CustomerInfo" tag is 77888. Look this text is not child of VCID, it's second child node of "CustomerInfo" tag.
NodeList childNodes3 = item4.getChildNodes(); // Returns null because <VCID/> node is empty.
String nodeValue = item5.getNodeValue(); // Returns 77888 ( text node ).               Regards,

Error when loading java spades applet

I updated the new java now i can't play spades.
I am unable to uninstall java and reinstall because it was originally installed under a user that has since been deleted from my computer.
Is there anything I can do? I am able to play other games online like gin in yahoo but the spades applet will not load. I have went and made sure that the settings are set to use browser.
I am just not sure what else to do can you please help me?
My husband had this problem before and I uninstalled and reinstalled for him and it worked. However this seems to not be an option for me because of the user problem.
This is what I get in the Java Console.

Sizing DOM trees created by Oracle Java XML parser (v2)

Hello,
Has anyone seen/got any formulas that can be used to calculate the DOM tree memory requirements for a given XML document.
My team has developed some software that, acts like an XSLT, and it runs out of memory for bigger documents. I am able to allocate more memory (usuing java -Xmx<larger figure>) to the process but it would be nice to go to my team leader and say that a file of a given structure would require so much memory.
At the moment, we are guessing and using the Runtime.getRuntime().freeMemory() and Runtime.getRuntime().TotalMemory()
to provide some very rough estimates.
XSLTs wouldnt be able to do what we want. If I could give the team leader some figures then he may be able to justify converting the code to use JDOM instead of a DOM tree.
Thanks in Advance.

Can you paste your java code here ? I assume, you must have tried type-casting.
