XML Parsing in the context of J2EE

i call EJB-method in an applicationserver that transforms data from a database into XML and returns a Java-String representation of the XML-data.
I need to parse the XML-String in a JSP-page in order to show the data in a HTML-table.
How can i handle this job easy without slow down my web-application?
Any helpful hints welcome!
thanx in advance.

Use JDOM to parse your XML structure: it has the reputation of being faster than JAXP.

Remove xml parser from the database

I am deinstalling a version of xml and putting a newer version of
it. how do i do that? I know that there is something like
dropjava , but still there are other packages which are loaded
into the schema. I want to clean out the earlier version and
install the new version in a clean manner.
Thanks

you'll need to write SQL to write SQL
based on the USER_OBJECTS table
where:
SELECT 'drop java class '''| |
dbms_java.longname(object_name)| |''';'
from user_objects where
OBJECT_TYPE = 'JAVA CLASS'
and DBMS_JAVA.LONGNAME(OBJECT_NAME)
LIKE 'oracle/xml/parser/%'
This will spew out a set of DROP JAVA CLASS
command which you can capture in a file
using SQL*Plus':
SPOOL somefilename
command. Then run that spool file as a
SQL script and all the right classes
will be dropped.

Problem to swap XML parser

Hi all,
I am trying to replace the official oracle XML library by apache xerces on a soa suite 10.1.3.1 developper hosted on a linux red hat platform.
I have found a how to on oracle web site (http://www.oracle.com/technology/tech/java/oc4j/1013/how_to/how-to-swapxmlparser/doc/readme.html). I hadn't found any archive containing the source so I have buid a simple test using EJB 3 (In fact, I have created a "hello word" session bean that return a String containing the Dom builder factory class name).
I have create the shared library using Entreprise manager as described in the how to.
My test works fine if I deploy it with the default XML factory but if I add the following lines to the orion-application.xml, the deployment process ends with a null pointer exception :
<imported-shared-libraries>
<import-shared-library name="apache.xml" />
<remove-inherited name="oracle.xml" />
</imported-shared-libraries>
I have tried to deploy the test using the entreprise manager web UI (as explain in how to) but the result was the same.
I have tried to remove the "<remove-inherited name="oracle.xml" />" line but in this case, the XML parser still the oracle one.
Do you know if the library specification is available in the last soa suite ?
Thank in advance for your responses.

Andre,
Thanks for your interest on my problem.
In fact, I have created a test with just an interface and a class. No additional jars are added at compilation or ejb creation time.
My java code is very simple (I have just copied the example main method and convert it to a SOAP method :
package be.test;
import javax.ejb.Stateless;
import javax.jws.WebService;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
@Stateless
@WebService(endpointInterface = "be.test.Test")
public class TestImpl implements Test {
 public String test() {
 DocumentBuilder builder=null;
 DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
 try
 builder = factory.newDocumentBuilder();
 return " DocumentBuilderFactory Instance: " + factory.getClass().getName() +
 " DocumentBuilder Instance: " + builder.getClass().getName() +" "; }
 catch (Exception e)
 return "Error processing DOM -- " + e.getMessage();
Unfortunately, I think that the problem may come from EJB 3 stack that does not support an other XML library.
Thanks again for your help.
Best regards,
Alexandre

How can I use a 3rd party XML parser such as xerces with OC4J ?

Hi all tech experts,
I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
installed Portal and Wireless and OracleAS Infrastructure on the same
computer.
i tried all the solutions on this thread
Use of Xerces Parser in out application with Oracle App Server 9.0.4
but still fighting.
I have also posted this query on OTN on following thread
How can I use a 3rd party XML parser such as xerces with OC4J?
but no reply....
Please help me on this issue.
Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
Thanks for your help.

Exception in XML Parser

Hi all,
I have a file-XI-file scenario.
In this scenario the Transport Protocol used is FTP.
The remote sender and the receiver system have Golden FTP server installed.
The xml file is getting properly picked from the sender system. The format of this file is:
<?xml version="1.0" encoding="UTF-8" ?>
<ns:file_mt xmlns:ns="http://namespace4BPM1">
<file_type>binary</file_type>
<file_name>input</file_name>
<file_ext>txt</file_ext>
<content_dt>
<firstname>neetu</firstname>
<middlename>k</middlename>
<lastname>gupta</lastname>
</content_dt>
</ns:file_mt>
But the reciever file adapter is giving the following error:
Receiver Adapter v1027 for Party '', Service 'Receiver_Service':
Configured at 10:21:05 2006-06-05
Last message processing started 10:21:35 2006-06-05, Error: Message processing failed with java.lang.Throwable: ftp access error: java.lang.Exception: Exception in XML Parser (format problem?):'java.lang.Exception: Message processing failed in XML parser: 'Conversion configuration error: Unknown structure 'ns:file_mt' found in document', probably configuration error in file adapter (XML parser error)'
The parameters specified in the receiver adapter are:
Connect mode: per file transfer
Transfer mode: Binary
put file: directly
file type : binary
I also tried sending the file after removing the structure 'ns:file_mt', but it gave the structure missing error message.
Pls if anybody could guide me as to what should be done.
Thanks in advance.
Regards
Neetu

check the document name in file adapter configuration channel and message type name of the interface and name space..both should have same name...

I looked very well, there was'nt any error on line 24 about "<", I think if the size of faces-confic.xml file increased JDeveloper XML Parser cannot parse with high file size, what're other solutions?

XML Parsing. Just need some guidance.

Hi,
This is my project. I need to be able to read in XML code in my java program and then do necessary tasks such as updating my oracle database with the values. I heard and looked at the java API for that but Im not so sure xml parsing is the correct words that I should be using. Does anyone know of a way to do this or at least somewhere that I could go look for an example.
Thanks in advance.

Hi!
What you are looking for is either SAX (Simple API for XML) or DOM (Document Object Model).
Look here for a SAX-Tutorial:

There is a xml parser written in pl/sql

Hi everybody,
We know xml parser for pl/sql is based on xml parser for java, that is, we need the Jsever running. However, Jserver needs 60-80 MB of memory and initially we don't need Jserver, except for xml parsing. Then:
There is a xml parser written in pure pl/sql ?.
Thanks for your help!
Jairo.

PL/SQL is not sufficient to write for XML Parsing. The implementation is either in C or in Java.
If you use Oracle9i, you can take use of XMLType for the C-based XML Parser.

XML Parser, Class Generator demo problem

Hello,
I have downloaded today the XML Parser and the Class Generator. I have successfully compiled the SampleMain.java coming with the kit. When running it there is a problem with the expected DTD filename input.
The program prints out the needed format as:
Usage: java SampleMain [-root <rootName>] <fileName>
fileName Input file, XML document or external DTD file
-root <rootName> Name of the root Element (required if the input file is an external DTD)
Whatever I try as DTD filename input fails.
I work on Windows-NT!
I have tried running with JDK 1.1.7.a and JDK 1.2.2.
Thanks, Yigal.

java SampleMain Widl.xml
or
java SampleMain -root WIDL Widl.dtd
Make you have Widl.xml and Widl.dtd are
in the current directory. Also, remember
Java is case sensitive.
If you are still getting errors, please
post the error message.

XSD Validation with ABAP XML Parser?

Hello there,
i'm loading xml files into a R/3 System. This all works fine with the standard XML Parser.
The XML Files are based on a .xsd structure that is assigned to each file with a external link.
To be sure that the xml document conforms to this .xsd structure i would like to check against it.
For that i would like to hold a .xsd structure string in my abap programm.
How can this be accomplished? Is this possible anyway?
Greetings and many thanks.

Why can't Oracle XML parser import a Xerces node?

I have been using XSU to obtain query results in XML as a DOM. Recently I tried to use the Document.importNode method on the generated DOM where the node to be imported was generated using the Xerces parser. The Oracle XML parser gave the following error:
java.lang.ClassCastException: org.apache.xerces.dom.DeferredElementImpl
     org.w3c.dom.Node oracle.xml.parser.v2.XMLDocument.importNode(org.w3c.dom.Node, boolean)
          XMLDocument.java:1247
I can get around the problem by parsing the XML I want to combine with the XSU generated XML with the Oracle parser, however, I would be happier if I could configure XSU to use Xerces (or another parser) via JAXP.
Will XSU have JAXP support? What is the cause of the exception above?

That is why you can't import.
Will XSU have JAXP support? What is the cause of the exception above?Why you need this? Any requirement from your application?

Does Oracle XML Parser support Content Validation

Hi there,
Could someone out there give me a hint on whether the Oracle XML Parser has the capability of handling Content Validation? If yes, what's the mechanism behind it?
From my understanding of the Oracle XML Parser, even with the validating mode turned on, the parser only validates the XML data against the DTD (if any), which involves checking whether or not the attribute names and element tags are legal, whether nested elements belong to where they are, and so on. But I dont see any Content Validation. And my guess is that this feature, namely Content Validation, is simply not supported in the current version of the Oracle XML Parser. Am I right?
Any suggestion would be greatly appreciated. Thanks.

WebLogic's High-Performance XML parser

I understand that 6.1's high performance XML parser is the replacement of 6.0's
custom generated parser. Per the documentation, I need to set SAXParserFactory
to weblogic.xml.babel.jaxp.SAXParserFactoryImpl, but I couldn't find weblogic/xml/babel/jaxp/SAXParserFactoryImpl
in either weblogic.jar or xmlx.jar. There are bunch of weblogicx/xml/babel/* in
xmlx.jar.
When I call JAXP code, I got this error:
javax.xml.parsers.FactoryConfigurationError: Failed to find SAXParserFactory.
weblogic.xml.babel.jaxp.SAXParserFactoryImpl
javax.xml.parsers.FactoryConfigurationError: Failed to find SAXParserFactory.
weblogic.xml.babel.jaxp.SAXParserFactoryImpl
Am I missing something, or the 6.1 beta download forget to include the *.babel.jaxp.*
stuff?
Jim Zhou.

Jim,
Please don't use System.setProperty() in any server code. This was intended
as an example only. I think the XMLReaderFactory is not specified in
JAXP1.1.
Thanks,
Chris

Jim,
Here is a code fragment to acess the parser:
System.setProperty("javax.xml.parsers.SAXParserFactory","weblogic.xml.babel.
jaxp.SAXParserFactoryImpl");
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
parser.parse("yourfile.xml",defaultHandler);
"Jim Zhou" <[email protected]> wrote in message
news:[email protected]...
I just found out that XML Registry setting on SAXParserFactory does notapply to
XMLReaderFactory() and XMLReader:
XMLReader parser = XMLReaderFactory.createXMLReader();
I have to use SAXParserFactory to get High Performance Parser kicked in:
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
Is this the right behavior? Thanks for the help.
Jim Zhou.
"Jim Zhou" <[email protected]> wrote:
Chris,
Thanks for the reply. It still doesn't work. I think the problem is
that weblogic.jar
and xmlx.jar both does not have eihter
"weblogicx.xml.babel.jaxp.SAXParserFactoryImpl"
or "weblogic.xml.babel.jaxp.SAXParserFactoryImpl". So the current Beta
download
forgot to include the above classes. I might try download Beta again
to see if
any difference.

Jim Zhou.
"Chris Fry" <[email protected]> wrote:
Jim,
This is a mismatch between our beta and the final place that the
parser
will
live in the release, you should be able to get the parser by setting
the
SAXParserFactory to weblogicx.xml.babel.jaxp.SAXParserFactoryImpl (it
will
be weblogic.xml.babel.jaxp.SAXParserFactoryImpl in the final release).
A couple notes:
The parser only handles standalone documents, with no entityreferences
and
is optimized for small to midsize documents (IE soap and wsdl type
documents).
Pleas let me know if you can get it to work.

hi,
there are two versions of ldap supported in wls6.1 , ldapv1 and ldavp2
ldap v1 only has the functionality of listing groups.
but where ldapv2 doesn't have that functionality,
by looking at your config , it seems you are using ldap v2..
if u need that functionality u can use ldapv1.
thanks

Per a proof of concept, I am having trouble getting WL6.1 to see
group members as defined in iPlanet LDAP. I can see the groups,
but modifies to create groups only create them in the local DB.
Created users also only get placed in the local DB. I can bind
for searches as Directory Manager via ldapsearch and run queries,
and the DS gateway works fine. I can dump the LDIF file and the
entries look fine.
I copied and modified the template for the Netscape server and
have the realm setup per the GUI.
For sanity, everything is very generic as:
the Root DN is "o=test.org"
and my "Configuration" part from the config.xml looks like:
server.authprotocol=simple;
server.host=localhost;
membership.filter=(&(uniquemember=%M)(objectclass=groupofuniquenames));
server.port=390;
group.dn=o=test.org;
group.filter=(&(cn=%g)(objectclass=groupofuniquenames));
server.principal=cn=Directory Manager;
user.dn=o=test.org;
server.groupiscontext=false;
user.filter=(&(uid=%u))
I added the "authprotocol" as a guess. Note that the server is
running on port 390, this is not a typo.
Any ideas what is going wrong?

Using a xml parser with jbuilder

I'm using jbuilder and the required librairies I've just added require me to add an XML parser to the path. I've just downloaded one from www.apache.org.
How do I incorporate this parser into my project. I need to use the following packages but I'm not sure how I can put everything together.
If you understand what my problem is please help. Thanks , B.

Go to tools | configure libraries.
click the new button on the left
Type in the name you want the library to be identified with (XML Parser or something)
Choose the location (this determines how many people and projects have access to the libraries)
Click the add button and find the *.jar files.
Ok back out of the dialogs
Now select the Project Properties (or default props to have the library available to all projects, not recommended tho)
Select the paths tab
Click Add and select the Library you added in the earlier steps.
If you have any probs, www.borland.com has heaps of stuff on configuring libraries
