Vicky,
I am using both SPRING and Oracle XML features in a project and indeed the
oracle xmlparser installs itself as default parser.
To prevent this I start the VM with following settings (JDK8):
-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
-Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
This will force the use of default parsers that come with the JDK/JRE. And when
I need the Oracle XMLParser (e.g. when handling XMLTYPE records/columns from
the database) I use (within the code) the Oracle parser.
