I want to build web applications by using Java - What tools should I use? [on hold]

I know Java and I like to stick to it. I want to build applications on the internet where the user can login and use the software.

I want that the logic should be Java and I want to use JDBC as SQL driver.

But I need to use more tools. Can you tell me what I need to know?

• Spring?
• Sleneium?
• HTML5?
• CSS3?
