Looking for upload blob

[mindbend]

Need to make a website for a school project.
Decided to make a website like photobucket.

I got every page read, but the only thing missing is the uploading part.
Does anyone know where I can find some examples of uploading blobs?
Or mayb someone can share one.
The thing is that the pictures will need to be stored in the database, and that's causing most of the problems.
The storing and retrieving part.

I pref. not to use servlets, since I will need to explain the code afterwards, and normally a servlet contains a lot more code.

Thanks a lot, but could you also say what lib's I need to import?
It gives me:
Cannot find symbol
location: class SimplifiedJSPServlet
