What does this have to do with JSP anyway?

what'd you expect from an Indian site by homework kiddos for homework kiddos?

I usually recommend them to homework kiddos, provides a good laugh to see them trashing about ;)

So you come in here months later, create an account, and start flaming people?

If you'd looked carefully you'd have seen there was no question asked at all, fool.

of course you can have multiple forms. It's quite common in fact.
Of course each form stands on its own, don't expect values from one form to be submitted as part of a request generated when...

Servlet filters always run on the server.
They can provide services that have to run before the web application processes the request, like authentication.
A filter can intercept the requests,...

you can't. You can't mix text and binary content and JSP are designed for text.
While they can output binary content, they're not meant to do so and I'm not going to tell you how to do a bad thing...

this has nothing to do with JSP.

you don't want to do that. It's not what JSP should be used for.

says it all. Toplink can't find the jdbc driver for the database you're telling it to use.
Supply the driver and you'll get another error (or it might even work if everything else is correct).

nah. We use them to make fun of the kiddos instead ;)

and what have you done so far?
That's a very simple problem, should take a reasonably intelligent person with a bit of knowledge about the technologies involved no more than a few hours to implement.

no. That's not the way to use JSP so we're not going to help you do it.
We're not going to do what you want anyway, which is to give you a fully working application.

Do your own research, and...

and no, we're not going to do your homework for you.

and what does this have to do with JSP?
Or haven't you gotten the hint yet that you should never use Java code in JSP?
And the message that you should never put binary content in a JSP outputstream?

and then there's the use of the JDBC/ODBC bridge driver which is also a recipe for disaster.
And the bad "Title" tag in the html (browsers won't generally complain, but it's not correct).

what's missing is a good spanking of you for even attempting to do such a thing using JSP.

but what the heck does this have to do with JSP?
DSN is an ODBC concept, and has no relation to Java whatsoever.
It's also an utterly outdated concept for for example .NET.

and of course you should not do anything except displaying the results from a JSP.

don't do such things from JSP.

not urgent. Come back in a few years.

you can't, period.

if you're using tempfiles you shouldn't care where they are as they're temporary anyway.

don't use JSP to send email.

no, we're not going to tell you how to do that.

no, we're not going to help you with such rubbish.
Scriptlets are NOT to be used.
Database access from JSPs is NOT to be used.
Code tags MUST be used.

no, you don't want to do that.

there are no simple strut applications.

no, we're not going to do your work for you.
If you're too lazy to do a bit of research or too stupid to understand what some simple tutorials tell you, you shouldn't have that job (or be signed up...

the problem in this case is not with Eclipse, nor (if it works outside of Eclipse) with your application, but with you.
You don't understand how to use Eclipse, and you blame Eclipse for that rather...

if it says it doesn't exist, it doesn't exist. So you're missing those classes or don't have them in the right place.
NEVER try to second-guess error messages, they're correct (if sometimes a bit...

you can, but you don't want to.
It's not what JSP are meant to be used for.

that has nothing whatsoever to do with JSP. It's clientside functionality which means it's probably Javascript.

and how do you think we could help you (even had you asked in the right place?)...

no. that's defined by the browser. Most likely IE is just faster than is FF (wouldn't surprise me, it is faster in my experience) so it's getting a response and processing it before it gets a chance...

Do NOT use scriptlets in JSP.
And learn something about Java in general before trying JSP.

Lastly, don't blame Eclipse and the server for your incompetence. Blame yourself for not understanding...

You didn't post any "codes", you asked for people to provide you some...

that's one bad JSP. Scriptlets, no proper headers, etc. etc.

well, ANY version of Oracle released in the last decade has JDBC drivers.
Using the bridge driver is ALWAYS wrong! ALWAYS!

And so is doing database access from JSP.

You can't, period.
What you MIGHT be able to do (but not with a properly configured webserver) is to generate (using a servlet) a list of files that can be downloaded, and another servlet that gets...

you're wrong to ask that here for starters.
