first of all you need to know that servlets and JSPs are not complimentory technologies. a complex web application uses both.

1. servlets need to be configured in web.xml whereas in case of jsps no need.(exceptwelcome pages)
2.are u able to use custom tags in servlets?
3.there is only one stage b/w request and response but for jsps two stages:translation and compilation

JSPs is implemented as a servlet internally. For example, Sample.jsp gets translated into Sample_jsp.java which is the equivalent servlet.

It's faster to develop JSPs as you can implement both HTML and Java in same file. As long as what you are doing in Java is too complicated, otherwise maintenance JSPs could be difficult.

As mentioned in other posts, mixing Java into the JSP is not considered a best practice. Creating a poor application structure because it is (supposedly) faster to develop that way is not a good idea.
