Java Programming

Hi
I have created a exe of my application using Jar One.
I am using SAXParserFactoryImpl in my code for parsing.
I have added this jar xercesImpl.jar in Jar One. Because it is added in my class path so this exe is running well on my machine.
I have also set System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "org.apache.xerces.jaxp.SAXParserFactoryImpl");

Does it any posibilities to get following exception ?
+"javax.xml.parsers.FactoryConfigurationError: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found "+

While i run jar on my machine it is running without any error but when same jar get run by client , getting the above mentioned error.

If yes then can any one let me know that which condition could be cause for this exception.
