armen donigian: 1. Can a developer be able to use JPAContainer AGPL 3.0 for profit making sites without disclosing the source code?

No. JPAContainer is dual-licensed, which (basically) means that you can buy a license (from Vaadin Ltd) to use JPAContainer commercially.

For more info on the Dual-Licensing, see this sticky post.
For more info on the AGPL, the wikipedia article is as good as an summary as anything else

2. If not, what data binding options besides JPAContainer can I use for a profit making site without disclosing the source code?

Several are available as addons.
Or, you can write your own - depending on your requirements, it's needn't be too difficult (the Container API has lots of superflous stuff that you often don't need to implement. The tricky bit is finding which bits those are!).

For my projects, we only use the container for reading (and manage the writing ourselves); our containers actually talk to a separate server, using our own interfaces and methods to query the database (i.e. it's an n-tier client-server configuration)

HTH a little,

Cheers,

Charles.

Thanks Charles for your post.

...you can buy a license (...) to use JPAContainer commercially.

To be really exact, AGPL does not mind if you use the library for commercial use, it just disallows closed-source use (or use with an incompatible license), which you probably meant to say.

Well, the two things correlate rather heavily, so in practice it's usually the same thing.
