Post&submit text to a form in java

[long_john321]

Hello all,

I am a Java developer and am wondering how do I use a java program to post to form and fill in some text on webpages?
example: do a program that posts a message to:

http://long_john321.t35.com

thats a site done by me to test this.

I would be thankful if anyone would tell me how to do this or give a hint to a program w/ source, howto, tutorial or book.
Thanks!

Here's a link to some opensource web-crawlers written in Java:

Not sure what you are asking.
Is the code you want going to run on a server or on a client?

On a client your java program would do a HTTP GET to a server, get its HTML with the <FORM and then create the needed response and send it back to the server following the rules specified in the ACTION= tag.

What you need to do is JSP and servlets.
JSPs are webpages with java built in and servlets are used to use information in a form. There are two types of methods POST and GET both do the same thing. If you research servelts and JSPs they should be of help to you.

Okay thanks for all the good info! But I think some ppl have misunderstood my question:
These are the premises:
*It needs to work for a PHP site (like the one I made) /no jsp,cgi
*I dont need to have the sourcecode, that means the program is like doing it "manually" in a webbrowser but no clicking.
*pure client-side program of course

Short summary: if you cant get the idea/program/pseudocode to work for my site I provided then its not the right program, im afraid

And Norm, could I get some pseudocode on that idea you had?

client to web, auto...let's see:
- client wsave some data to a db, put a status flag=0
- on load, let the form web page xtraxt from a db, change the flag to 1

workable?

I assume that the java program you are talking about will run on a client machine and will do what a user might do with a browser. Ie read a web page with a <Form, fill in the fields/check the boxes and submit the results to the server.
I don't know how to parse an unknown <Form. Perhaps there are classes to do that.
If you know what the <form looks like, you can build a URL with the response fields set as needed and send it back to the server.
If there is a parser for the HTML <Form, then the job is a little harder, but doable.
In the doc you need to look at the format for the URL sent by a client when 'Submit'ing a <form.
There is GET and POST to consider.
There also might be Cookies to return to preserve state on the server.
