Whatever I am asking is equally applicable to any servlet engine conforming to the
servlet API2.2
specs. Sometimes when you are trying to make a servlet a generic one you expect to get
parameters from the user and not
hardcode them into the app. So you have two options - take the values from a
properties file or from the servlet init params.
Unfortunately, while a servlet is running(now this might get Tomcat specific) the
current directory of the servlet is the *server-root* e.g. /usr/local/tomcat. So if
you try to read/write files, keep this in mind. To find out what is the current
directory of the servlet try the getRuntime().exec() function and do tell me what your
engine comes out with.
Now somethings like databse name.username etc. are common over all servlets. You would
like to send all of them to the servlets as init-params. What do you do? copy-paste it
for each servlet in the web.xml??? Or am I missing something BIG around here?? ;-)

My observations above might help you. I also have had difficulty reading files using
servlets.

I saw a question like the above at the tomcat faq-o-matic. I haven't used the
HTTPSession class much till now.To tell you the truth I have just started servlets
couple of weeks back.
