Subsitutes for JSP and Servlets ?

I am thinking of doing a SCWCD certification. But I have a doubt before I begin. Are there any good substitutes for JSP and Servlets ? What is the popularity and importance of these technologies ? Is there anything else that I need to learn besides these two (eg a database) to create a full fledged website - back end and front end ?

IMO, there is no subsitutes for jsp and servlets in jee . and data base tier(storage area) is completely different from jee . of course, you need them to develop your applications.

All the web frameworks sit on top of servlets (at least) and possibly JSPs. The concepts are very important.

There are alternatives; FreeMarker for example, as a templating engine. And frameworks like Play don't use Servlets and JSP at all.

But as this is the Job Discussion forum, you ain't going nowhere in the Java web world without a sound grounding in Servlets and JSP.

Jeanne can you tell me what does "sit on top of" mean ?

It means that Servlets and JSP are the foundation upon which the frameworks are built. Frameworks such as Struts, FrontMan and Spring MVC use servlets and JSP in a non-occluding manner. If you don't know servlets and JSP you aren't going to be able to use the frameworks effectively.

Good point about Play. I'm thinking that shouldn't be someone's first Java web framework though. Especially as Bear notes when looking for a job.

Indeed. Most people will never have heard of it and even if they had, they won't be too impressed unless they're exclusively using Play (and that'd be rare).

I like Play for certain projects, but it's a niche framework at best. Especially now that they are focusing more on Scala than Java.
 
I agree. Here's the link: http://aspose.com/file-tools
