And here's the source code: http://pastebin.com/N7EQz4Lk Feel free to correct any mistakes in my code. Thank you.

Just a "hello world" message.

Yes, the problem has been solved with a help from Mario's ebook (https://bitbucket.org/leledumbo/books/downloads/fpwebtutorial-chromeprint.pdf). Mario is also known as @leledumbo at Lazarus' forum.

Yes, I should have figured it out earlier, but it's been a long time since the last time I used TDataModule, so there are many things that I forgot about VCL. In fact, that's the main source of my problem. Once I used the CreateNew constructor, everything works as expected. Though I still have many things to learn to understand how the fpWeb works. :)

I don't mind the clasess, but I do mind the RAD part. A web app development should be able to be done without the RAD part because in some cases we don't always have the access to use the RAD.

I did. But all the examples I found are using Lazarus aka RAD. Hence this email.
fpWeb —and all the gems of FCL— do really need proper and complete documentations. It's hard —especially for Pascal newbies— to learn FCL from the source code alone. Documentation is the main and first obstacle for everyone who like to use FCL to its potential. I wish I could help.
Thank you for the reply, Michael.
