By setting a few properties,
-Datg.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.ja
xp.SAXParserFactoryImpl -Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.
jaxp.SAXParserFactoryImpl -Datg.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.inter
nal.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.int
ernal.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.transform.TransformFactory=com.sun.org.apache.xalan.internal
.processor.TranformFactoryImpl
the origianl error went away. But atg server can not process any .jsp or .jhtml file.
