What is EJB (Enterprise JB)? Is it in any way related to JSP or Java Servlets or is it an individual component.?
And what bout its relation to Swing/AWT.
Also are there any problems installing on other OS's other than ms Windows...like maybe for eg....mac, sunos etc. i mean does it have any serious bugs in it??
ak.

EJB is nothing but Server Side usable componenets.It is pure java Technology for developing componenets by Sun Microsystem.Like COM of Microsoft.
JSP is Java Server Pages which is nothing but combination of HTML and Java Scriplets.
If you have to develope any application in pure Java.Then instead of using the HTML now a days we go for JSP.While we call a JSP page it generates a Servlet.
In Software Industry the earliear all processing is done on front end ( Client side).As due to change in the front end lots of problem comes in Existing Technology.So the load is shifted to the Server Side.Java Servlets plays very important role in handling the load on Server side.But that is effecting the speed issue.There comes a middle layer called Application Server which sits in middle between Client and Server.For balancing this load on Server the Application Server are used where all the Business Logic is designed and EJB is the technology which now a days used for seperating this Business Logic from the Back End Server.
EJB is an individual componenet.But together they are used in developing a Big Secure Application.
Client Application Server BackEnd
JSP EJB Servlets
Sorry for giving this lengthy Description.But i feel that will help you getting an idea of JSP,Servlet and EJB.
Lets see if you get anything from it or not.Please let me know if anything is not clear to you.
 
Don't get me started about those stupid light bulbs.
