Urgent: Xerces 1.4 .2 (and higher) and WLS 6.0

Question

Hi,
We want to use the Apache Xerces 1.4.3 validation to .XML Schemas and we try to
integrate it in WLS 6.0. sp2
But we are ahving trouble to get the parser working.
I allready tried to explicitly stating to use the org.apache.xerces.framework.DocumentBuilderFactoryImpl
of apache ..... but then the program stops when asking for a DocumentBuilder.
anyone... knows how to get Xerces 1.4.1 (or higher) to be used in WLS6.0 sp2

I'm using Syslog, JAXP, Xerces 1.3.1, jdom-b7 with WL 6.0sp2 without
problems ( after getting a patch for Syslog )
Use the Xalan that comes with Xerces, not the independent download.
Put xerces.jar ahead of weblogic jars in the startup script
Setup the external registry.
config.xml:
<XMLRegistry
DocumentBuilderFactory="org.apache.xerces.jaxp.DocumentBuilderFactoryImpl"
Name="Apache XML registry"
SAXParserFactory="org.apache.xerces.jaxp.SAXParserFactoryImpl"/>
Set the external registry to be in use.
config.xml:
<Server ... XMLRegistry="Apache XML registry" ... >
If you are calling SaxBuilder() without specifying a class for the builder,
JAXP throws an error. Syslog has a bug which does that, and the patch will
be included in the next release. But if you use:
startup script:
java $JAVA_OPTIONS ...
-Djaxp.debug=true -Dweblogic.xml.debug=true -DSyslog.config.xml=config/gulch
/syslog_config.xml -DSyslog.xml.parser=org.apache.xerces.parsers.SAXParser
-Djavax.xml.transform.TransformerFactory=org.apache.xalan.processor.Transfor
merFactoryImpl ...
weblogic.Server
com.protomatter.syslog.Syslog.java:
String parserClass = System.getProperty("Syslog.xml.parser");
SAXBuilder builder = null;
if (parserClass == null)
builder = new SAXBuilder();
else
builder = new SAXBuilder(parserClass);
It works.

Hi,
We had also smilar problem. I used JAXP and SAX 2 implementation withapache xerces
in our XML application. I was not able to to register this package inweblogic
console. Weblogic sets system property to default :
javax.xml.parsers.SAXParserFactory =weblogic.xml.jaxp.RegistrySAXParserFactory
>
It didn't recognize the XML registry definition and it didn't recognizethe system
property that I defined (even in the application).
In weblogic 5.1 we put in the classpath our JAXP jar file in fron of theweblogic.jar.
In weblogic 6.0 this did't work now I use SAX parser from xerces withoutJAXP
SAXParserFactory.
It seems like weblogic has older version of xerces and it does not allowto use
another package because of RegistrySaxParser.
I don't understand why there is no information in weblogic web sites, itseems
many people having these problems.
Good Luck and
best regards,
