I'm new in the field of J2EE application development. I'm confused that when exactly the servlet technology was introduced. I have two books, one says that it was introduced in the year 1999 while the other contradicts and says that the year was 1996. Which one is correct?

What about the SingleThreadModel interface? Is it deprecated by the J2EE 1.4 spec?

I know that it is an evil. Implementing it is like killing ur performance.

Regards,
Austin

I have notes in my servlets book that API 2.0 was released in 1997, the first Servlet Development Kit in 1998 and version 2.2 of the API in December 1999. I have no idea about APIs prior to 2.0.

So will it be correct to say that the Servlet technology was inroduced in the year 1996.

Am I correct on the SingleThreadModel interface? Is it really deprecated by the J2EE 1.4 spec.

SingleThreadModel is not deprecated in the 2.3 servlet API - however it has completely fallen out of favor. If you think you have to use it your architecture is probably wrong.
I believe it was originally introduced to help beginners make the transition from programming in the single-user-desktop-application model to the multiple user stateless client-server model. A pretty big conceptual jump.

It is sorta covered in the JavaRanch Style Guide.
