Class Loading in Web Tier (Solved) 2003-07-31 - By Vikram Naik
Back
Hello People,
For now atleast I have solved the issue of Class Loading by Sub-classing
the Parser and overiding the methods where class-loading is done in the
parser. So now virtually the parser is in the web-tier
and hence have visibility to the classes in the web-tier.As xerces is an
open-source, had look at the code and decided overiding two methods where
class loading was done in the parser.
But still I have a query regarding the packaging for an enterprise
application.
Should the ear file contain only the ejbs and a war file with only web
resources with jsp,servlets , htmls and images, and the libs say a jar doing
some xml parsing be placed in system lib.Can it also help as far as
maintainence is cconcerned.
Thnaks & Regards,
Vikram Naik

probably is a websphere.jar some where which is the J2EE implementation of
IBM).

observance of license rights would seem to be to devise a robust means of
finding required 3rd-party libs from standard installation locations. Or
specifying the locations might be a manual step to deploying the distributed
application, i.e., a "deployment classpath".
