Actually i have one question regarding javascript. Couldn't find any section for it so am posting it here.

I am receiving some data on my jsp page. This data could either be a url or an attachment. This data appears in the form of a link . Now when i click on this link,it opens the attachment in another window. I need to disable the right click on that window ,for that attachment. Can anybody suggest me a way out???

If an application server already has a web server configured in it then why do we user an external Web server to support an application server.

For eg: I am working on Tomact 4.1 and i have been asked to user Apache web server with Mod_jk as the connector??

Doesn't tomcat 4.1 have it's own webserver?
