servlet optimization

2000-11-24 Thread deepak gupta 

hi all,
I am working on a problem where we have the option of
having 50 servlets =
containing all the 50 classes with proper methods
inthem
with parameter containing the class required

OR

seperate servlets for each and every one

could any one guide me which approach should we follow
It would be of great help if you could give me a
quantative analysis.

thanks in advance
deepak gupta

setAttribute is defined in servlet API 2.2. you might be using an older
version. so check your version.

That's strange -- setAttribute should be able to take in any object.

 More specifically, take your result set and place it
 in a collection
 and pass the collection to the JSP. (Check the
 archive for exactly how)

  Yes i have but what exactly is your problem
  You simply have to create the connection in your
 bean and call
  that method
  on your JSP page.

 I do a _lot_ of work with servlets and many of them

 I'm trying to decide whether switching over to JSP
 is worth it for
 me.  I'm especially concerned with being able to
 accept form
 parameters whose names I don't necessarily know.
 For example, I often
 have tables of form parameters that have names like
 "MyParam1",
 "MyParam2", etc. and I use a simple loop in a
 servlet to read these
 in.  Is there a way to design a bean to accept
 parameters like this?
 What about nested ones (MyParam1Sub1, MyParam1Sub2)?
  Also, is there
 an easy way to display things from a database with
 jsp's?

 thanks,
 eric.
