Need Suggestion on the xml parser to be used in weblogic env.

Question

Hi All,
1. I would like to know what is the parser suggested to be used when our application is running in the weblogic env. We have xerces parser already shipped in along with jdk and oracle's xdk parser is also available in the env.
Kindly let me know what is the suggested one to use?
2. In one of our applications, jaxp factory (javax.xml.parsers.DocumentBuilderFactory) is explicitly set to xerces's (com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl).
Now when we changed it to use oracle xdk parser (oracle.xml.jaxp.JXDocumentBuilderFactory), We are running in to issues like 'IllegalArgumentException :not able to set Schema in setAttribute()' as a File Type.
Previously, we used to set the Schema as File Type when xerces parser is used and that used to work fine.
Kindly let me know the way which is accepted by both the parsers.
Thanks
Rajesh

Use the default parser.
By default, WebLogic Server is configured to use the default parser and transformer to parse and transform XML documents. The default parser and transformer are those included in the JDK 5.0.
The built-in WebLogic Server DOM factory implementation class is com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl.
The DocumentBuilderFactory.newInstance method returns the built-in parser.
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
