Re: FTP From JSP
My two cents on this issue:
For most average sites, Both these tools work well and the speed isn't the
issue but rather your shops expertise and style that really decide which is
the better product. I have to smile since in these enviroments its not the
programming language that is to blame for bad performance but badly
programed code that kills the project or response time. So pick the
programming language that matches your shops programming style. If you are a
cookie cutter style shop then ASP is your tool, its great for cut and paste
coding. IF you have a strong object based shop then JSP will rock over ASP.
But it really comes down to style.
When speed and size are the main issues then based upon platform
requirements you can choose the approriate solution (jsp vs asp) Both asp
and jsp can be made to rock the world, but in each case its when your
plaform is tuned to match the solution. So its still a style issue, a style
of hardware that your shop excels in. Pick the solution that matches your
shops style yet again.
So from my point of view both JSP and ASP are great solutions as long as you
use them in the right enviroment and programming staff.
I have to admit my bias's, I just love JSP, it is just plain fun to program
in a good object oriented enviroment, Plus it offers wonderful solutions. If
I had to choose one I would choose JSP but on saying that
I will also admit for the next year to come JSP will always be playing catch
up with ASP.
This is due to two reasons.
1) ASP is just easier to learn (ok JSP is easy to learn , but to really
unlease the power of JSP, you also need to know Java and you should
understand Servlets and JDBC and these 3 extra burdens make the JSP learning
curve a much steeper one. Add on top this JSP is newer and the educational
materials are still in mid stages of chaos, but with a smile I can say this
is finally turning around)
2)The ADO object and the ease of using stable ODBC connections. In my
opinion JDBC is easily a year behind the functionality and ease of use of
the ADO Data connectivity enviroment. And its these two issues that
ultimately which will keep JSP behind ASP in the numbers.

Let's explore more on a related topic as I like this {:))..
I still can't figure out why the sentiment against MS when that it is doing
a good job bringing out high performance softwares ? {:(
(I am also not an avid MS fan although I worked under Bill's army of
software developers. 'got to stay neutral to survive in this competitive
world {:)
Maybe, so many people failed to adopt/learn C++ nor liked basic for its
unelegenceness (both are extremes) that they need something easier but
elegant to work with and then somebody who is fed up with C++'s short
comings when he is working for this networked devices' project came up with
a simpler to use (but of course with performance trade-offs) and more
adapted to internet programming that is now the famed, the holy grail, the
numero uno ballerina of programming world, JAVA.
Or, is it due to MS' competitor SM's successful advertisement of JAVA that
lured away programmers from C++'s/VB's world. And then, naturally, all JAVA
related technologies, environment get to be embraced by the whole
programming community (or at least all the noisy ones who are not pro-MS).
Or rather, JAVA is the next natural evolution of C++ programming language
and that it was embraced right away by developers who saw all the
advantages
of JAVA as vs. C++ (not to mention basic since it doesn't rise up to the
elegance level {:).
But indeed, how can a JAVA compiled to bytecode (that needs an interpreter
or a runtime engine) compete with the speed of a native, compiled to
machine
code COMponent. But JAVA is a language, therefore, it is not hopeless that
someday a compiler + JAVA runtime engine can match up with the performance
of a COM. But never to be better in performance, only in built-in features
and in simplicity.
Hardware performance, they say, will compensate for a software speed
inferiority. As such, it is better to have a more tamed development
environment rather than to have a better performing software dev.
tools/enviro. In this case, if JAVA is the next evolution of C++,
therefore,
given a better tamed JAVA environment means it is a better option to
choose.
But then again everything is relative. That's why SDE's are always the
heart
and sole of a software dev't project, they are the ones who design
optimize the software. No matter how good the features are if the engine is
slow and poorly architected, it will be a slow poke of a software.

Re: asp v. jsp/servlet environment? also called Re: FTP From JSP
---Snipped from JSPInsider article: ... these are good times to be a simple country programmer! Casey: To have life so simple is always a joy. Unfortunately,... Thanks for posting your site and the link to your first-in-a-series article. It presents an informative and intriguing comparison of asp to jsp. It seems a comparison is better made between MS IIS server-side technologies, including asp, with its limited internet server support (principally MS IIS), to server-side Java, including jsp, which is widely supported by most internet server platforms out there. In case some may perceive MS bashing, I like MS tools. I've developed sw for decades, using MS tools for a good part of that time. Among them, I develop in MS VC++ on an NT workstation/server, and run first-tests of C++ and Java apps on MS IIS. Yes, NT IIS is simple, easy to install and manage, but at best, MS IIS leaves ambivalence. MS IIS seems a little like Macintosh: a good platform without market acceptance in important application areas. The lessons of Apple Computer (Apple once held dominant market share) and Ashton Tate's dBase (ditto. Now, Ashton who?) resonate. Great technologies don't die, they fade into oblivion. (Does anyone remember Betamax, VisiCalc or VisiOn?). The argument in favor of MS IIS is that, for "small" sites, MS IIS (asp) holds its own in comparison to Java servers (and jsp), admitting that server-side Java is better suited for "larger" sites. Has anyone argued otherwise? Ultimately, it's unimportant how capable MS IIS asp may be. Use determines acceptance. Many dBase programmers have said, "dBase can do that," but dBase is not used for so many "thats." Similarly, at some point, IS resources turn away from MS IIS towards more accepted platforms. At what point does MS IIS and asp fade into oblivion? Your article suggests an expansive definition for a "small" site, raising a valid question as to how small is "small." Your term "users" seems more clearly called "client requests," since an Internet client-server "user" usually disconnects once the request is satisfied. To call 500 simultaneous requests a "small" site seems a bit much. A quick run at the numbers suggests that a maximum of 500 simultaneous client requests means that server capacity could far exceed 15 million hits per month, 500,000 per day. Shove most NT IIS servers into this environment would prove disappointing. The limit is one of acceptable usage. Of course, MS wants IS managers to believe the limit is the hardware, not the NT (Win2000) OS; perhaps they are right. Still, in my experience, MS IIS(NT/Win2000) is not the preferred choice for high traffic machines. Implementing asp-com technologies outside MS IIS is difficult, at best. IS management seems to accept the concept that MS IIS is acceptable for "small" i-server apps and most IS people feel comfortable saying Java is superior beyond some minimally "small" size site. One question is "How big is a "small" site?" Another question is, "Do you want to speculate with your, or your company's, resources on whether MS IIS will ever be accepted as suitable for serving a rapidly expanding client base with growing client needs?" Bill Gates says he's betting the company on his new net technologies, just as VisiCorp once bet their company on VisiOn (Visi-what?). Do you want to bet your project on MS IIS future, ignoring accepted MS IIS limits? This much seems most simple: Java servers are the accepted choice for growing sites with big-picture needs. Here, the future of MS IIS is simply speculative. Comments?

session.setMaxInactiveInterval("specify the no of minutes") for

two: Use session binding listener class which has two methods sessionBound
