Jakarta Slide on OC4J

Never give up (referring to this post). Finally got Jakarta Slide server running on OC4J. The issue was with XML stack, there seems to be some sort of differences between the default Oracle XDK and the XML stack used with Slide. Anyways, to get Slide running you should define the Xerces and Xalan parsers as the JAXP factories in the OC4J startup.
Here is a sample startup script for my OC4J:

cd $HOME/oc4j/j2ee/home
java
 -Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
 -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl 
 -Djavax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl 
-jar oc4j.jar

Xalan and Xerces libraries should be placed under JAVA_HOME/jre/lib/ext and remember to give at least read access to the account running the OC4j container.

I have the same requirement of using Xerces and Xalan for my application to make it run on standalone OC4J 10.1.2.0.2. I tried that solution you propose by was getting the NoClassDefError. I did place the xerces and xalan jars in the jre\lib\ext.
There is a -Xbootclasspath solution which ORCL proposes. that did nto work for me. Are you saying your solution is better?
Please advise.; 00:56
