setting system properties

Hello. I'm trying to set the system property that controls which implementations will be returned by the JAXP API's. I know what property I need to set, that's not the problem. I just need some advice on the various ways in which one can set system properties in a J2EE environment, and the pros and cons.

For instance, I know that i can set it on the command line as a parameter to the java command that starts the application. Or i can set it in the code.

I'd appreciate any recommendations or suggestions.
