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!
