hello everybody,
Hello.
a silly doubt:
No doubt is silly, unless proven otherwise.
what is difference bet a application server and webserver.
an app server serves applications. a webserver serves web
pages.
what is that an application server can do and not a webserver cannot.
apples and oranges, I wouldn't compare.

how can one deploy servlets or jsp pages weblogic application server.
I would start with downloading it and going thru the examples.
what is the philosophy behind an application server.
varies. but they most of them confirm to J2EE stds for java.
what are the famous application server.
tomcat, weblogic, websphere to name a few...not all have
the same capabilities though.
Do we need a webserver even if we have a nice application server.
again, apples and oranges, it depends.
many questions...???
definetly! we recommand you limit your posts to max 2 or 3
qstns.
regds.

App servers are component transaction monitors which will take care of transaction, security, session management,etc., including serving webpages and act as a container for EJB's..
On other hand webservers exclusivly serve webpages and act as a container for servlets and jsp..
Generally appservers includes a webserver in it.. but if u have large number of static HTML pages, in view of improving performance and to have more security, people will go for an additional webserver..
Most popular Appservers r Weblogic, Websphere, Iplanet..
U can use weblogic server as a webserver for development..
Hope i answered u'r questions..

I would not use Sun's Java Web Server, it is very non standard, and not a good server to learn about, as what you learn will not be very useful with other servers.
20 users with a web-based user interface does not sound like "real time" to me. That's quite a low load for most web servers, so any reasonable server would probably do the job. Can you tell us some stories about how the proposed system might be used, and what it might be used for?

hi frank,
yeah it is not a big industry ,its a hospital and the clients are not many. the clients need to come to the hospital. there ID is scaned by a barcode reader,and enter some information about about there improvement. like saying yes or no or what level of improvent from 1 to 10. there will be some 20 touchscreen terminals in the hospital located at different places. and the doctor reviews them and give suggestions.OK this is all about it.
there may be a easy way to so this but i want to do using jsp/oracle
so i guess i will use weblogic server what do you guys say.
thanks..
Rayudu.
