Question : Websphere jaxp.propertis file

Hi All,
When I have deployed my application in Websphere 6.1 in linux environment it stops working.
The struts modules was giving following error.

org.xml.sax.SAXNotRecognizedException: http://apache.org/xml/features/validation/dynamic
      at gnu.xml.aelfred2.JAXPFactory.setFeature(JAXPFactory.java:102)
      at org.apache.commons.digester.parser.XercesParser.configureXerces(XercesParser.java:185)
      at org.apache.commons.digester.parser.XercesParser.newSAXParser(XercesParser.java:138)
      at org.apache.commons.digester.ParserFeatureSetterFactory.newSAXParser(ParserFeatureSetterFactory.java:73)
      at org.apache.commons.digester.Digester.getParser(Digester.java:682)
      at org.apache.commons.digester.Digester.getXMLReader(Digester.java:891)
      at org.apache.commons.digester.Digester.parse(Digester.java:1572)

Than I applied below solution
Rename the jaxp.properties.sample (located in a folder similar to /opt/WebSphere/AppServer/java/jre/lib) file to jaxp.properties and uncomment the following properties.

javax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl

And it works fine.

Now the question is how will this affect the other applications running in this environment?

Thanks in advance!

Answer : Websphere jaxp.propertis file

Are you using the struts that comes with WebSphere, or is there one bundled in your application?

If you have one in your application, what is the classloader policy?

Parent_First?

or

Parent_Last?
