hi,


Version 1: Difference between jsp and servlet is similar to the difference between asp and Internet programming thru VB...one is embedded within the html code and executed directly while another calls a html page according to the request

Contradiction : You can also embed servlet code inside a html page
<servlet>
.........
.....
</servlet>

Version 2: While a servlet is precompiled (thatz why it is in .class format) a jsp gets compiled during execution

These are several versions explaining the differences..but the main thing is a JSP is a servlet by itself which calls the servlet engine and execute the java code in it and displays the content...


[Does these things made any sense.....]

Take care,
Regards,

There are lots of differences between servlets and Jsp. Just to name a few,

Jsp is similar to Asp. Jsp does not have a .class file wheras servlets have. Jsp are compiled by the JVM during runtime(that means when you access the jsp file). The Jsp will be compiled into and ran as a servlet.

Jsp will tend to be slow when accessing it for the first time. Due to the need for compilation. Subsequent access will be fast.

Jsp is actually html + java. This allow users that are more well-versed in HTML to be able to use Java and the other way round.
