What does this have to do with JSP anyway?

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).

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It's also an utterly outdated concept for for example .NET.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.

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...

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

an even simpler solution is to check the timestamps on posts before replying to them...

says it all. You don't have permission to read that file.

by reading the tutorials that come with it and the JEE distribution from Sun.

and don't revive old dead threads to post nonsense "solutions".

and it seems the kid also misses a basic understanding of classpaths, server configuration, and a lot of other things quite apart from not knowing Java and having the terribly bad idea of using...

kid's still insisting on doing database access from JSP.
Maybe if it would stop trying that it would get somewhere...

I'm doing a bit of Oracle ADF, quite nice.

yup. At least 2 ways.
1) generate a bitmap using something like JFreeChart from a servlet that you link to through an image tag.
2) generate it as text using some CSS magic to make it look nice.

no. But when you go to that JSP you immediately create a new session :)

It is rubbish. It is fundamentally flawed by design.
If you don't want to hear advice you don't like, don't ask questions.

Redo from start.
Not urgent.
Rubbish code.

you should be able to do the entire project in a day or two if you type at a less than glacial pace.

We're NOT going to help you cheat on an assignment you had 2 months for that you can do in 2...

Most likely your html is not valid, and IE and FF deal with those errors differently, with IE being more successful at it than FF.

and that's after you stop trying to place business logic in JSPs.

not. That's not what JSP are to be used for.

classic example of "gif mi zu koduz", aka a homework kiddo that can't be bothered to do its own homework.
It probably didn't even bother to read the documentation I supplied, far too much trouble.

A bean has no "value".
What "doesn't work" anyway?
What do you expect to happen and what do you observe as happening?

4 letters: RTFM

hmm, most of those "tutorials" are either utterly and totally wrong or hopelessly outdated, "teaching" the JSP 0.9 coding style which has been out of favour with every serious code for the better...

pass the selected value back and set it as the "selected" attribute of the dropdown.

says it all, that variable doesn't exist...

not urgent. Come back next year.
Gives you time to learn about code tags, html, Javascript, Java, JSP, etc. etc.

usually you have a list of words and check each word against that list.
There are more advanced systems that do full lexical analysis to also take context into account but you're not ready for those.

if you're really a university student you above all have to use your own judgement and think for yourself.
When presented with a bad example you should have the intelligence to detect that and not...

yes, NEVER use Java scriptlets in JSP code.
NEVER do database operations from JSP.
ALWAYS use PreparedStatement for database operations.
ALWAYS use parameterised queries for database operations.
...

That's an html question...
You need to set the target attribute of the a tag to a non-existent frame, that's all that's required.

You should NOT connect to anything from a JSP. Do that in a servlet (or rather a business logic class called from a servlet) which the JSP form points to.
The servlet can then forward the request to...

as is a totally free version of Oracle 10g, and a development license of Oracle 11g Enterprise :)

if this site is going like the Sun forums we'll see kids requesting "send me ze koduz" for years to come.

You obviously don't return the values to the page for display after you handle them.

this has nothing to do with JSP...

And you seem to have defined your instance (I hope) variable conn as being of the wrong type.

Anyway, what you're doing is terrible. You should never open...

idiotic and highly dangerous to have anything in place that can bypass the normal request/response system and call any method it wants directly.

Security leaks guaranteed, such a thing is a major...

like I said, you don't realise what you're dealing with here.

What you're effectively saying is that you want to call private method on a class without having access to an instance of that class....
