Default Currently best technologies for "online shop".

Hello!

First of all - my first post so welcome everybody!

Now to the matter at hand.
I would like to get a bit more into Java programming. So far I licked a few technologies and made some not very complicated programmes. I want to create something more useful and concrete.
I would like to make myself a little online shop - with a cart and all the usual things.
Now I need a little help. I don't know what Java technologies are best suited for this task. If you could point me in right direction I would be really grateful.
Thank you all in advance.

PS. I really hope this is a right place to post this.

you can use very complete and pure java framework such as jsf or adf.

well, this is a tricky one - there are several professional standard frameworks in java that you could use. The choice will be down to specific requirements, experience, IDE and just general preference.

Spring offers a very popular framework which is pretty comprehensive (and just my personal preference ;) so you could look at their "petclinic" example for getting started:

Spring also has a product called Spring Roo, which brings Rapid Application Development to the party and give you increased initial productivity pretty quickly (although, if you are new to Spring, I would recommend you spending time understanding what is going on behind the scenes and how all the parts of the application are being wired together)
