Build a website using Java and web techonolgies.

I am planning to build a Community Website and I would like to use Java. Please provide me some suggestions in helping me to choose technologies and frameworks to create a simple website.
The main intention is to serve the community based on there posts. Web hosting, domain registration and simple look and easy to code is my best fit and target.

By "community based on there posts", do you mean forum software? If so, check out JForum (a version of which is used to run these forums here). If you meant something else, please be more specific about what that this.

No, I am not looking for forum software but i am trying to build a website and allow users to fill a form and submit there requests. I also want to broadcast messages to the community about the events going around the city. I am sorry if my requirements were not specific. I hope this gives a broader idea. If possible also try to upload photos and share.

If you simply want users to fill a form and submit their requests, why not try Google Forms

I'm afraid your goal is still rather unclear. So there would a web site where visitors would see these "requests"? How would they be organized?

By "broadcast", you mean email?

And what do you mean by "share photos" - would those also be displayed on the web site? How would those be organized?

I just want to create a website like http://www.southtexasaussierescue.org/. Broadcast meaning posting images on website. Email in some scenarios.

OK. Before choosing technologies, you would do the technical design. From that you can deduce what you need, which determines which technologies you can can (or should) use.

I'm not suggesting that this is the right solution, but that site is done using Joomla. Using a CMS (Content Management System) might be a consideration if you're not savvy enough to build one completely yourself. Be aware though that CMS's are not without their limitations.
