Here are two approaches:
1) Use the Robot class to drive the cursor and keyboard to do what a user would do when looking at a browser's window.
2) Send HTTP request to the server, read the html page, build a response page and send it to the server.

For solution 2) I suggest studying the HTTP protocol and HTML.

Check out Google. I'm sure it can find lots of sample code.

the problem is i don't know what to google exactly

**Norm** · 07-12-2015, 06:23 PM

I don't either. The project is in java and involves networking use of HTTP and HTML. Start with those.
You will need to try different search values to see what they return and refine the search args as you learn more about what is returned.

It sounds like Jaunt - Java Web Scraping & Automation may be really useful to you then. It makes it very easy to accomplish what you want to do, and they provide example code on their site.

Wouldn't it be much easier to find out how the POST is made from the webpage? Use Fiddler2 to see the POST data and rebuild that with your WebClient. Getting a HttpClient (Thank you Apache HttpComponents!) to do that POST for you would probably be the correct way. Screen scraping is frowned upon by most sites. Besides, one little HTML change and you're screwed. Ofcourse, when they change the parameters for the login, you run into problems as well. But that's price you pay for using a "service" you're not supposed to use that way.
