This change will generate JSON as required if the Java class contains the @XMLElement(required=true).

To add context, we are generating our Java classes from an XSD. The Java classes contain the @xmlelement(required=true) annotation if it is required. This change will add the required attribute when generating the JSON schema from the Java class.

Sounds good!

One clerical thing I need before merging this in is to get a CLA (https://github.com/FasterXML/jackson-databind/blob/DEV/CLA/contributor-agreement.pdf) filled, unless I already asked for a copy (I don't think so, but just in case we have one, let me know).
It's a standard one-pager, and just needed because many corporations want to know that there is a process to track contributions (specifically, Eclipse foundation verifies these diligently).
So if possible, could you fill it in (most devs just list themselves, no company, for what it's worth), and scan and send (or attach it)? (can add to patch, or email me, 'tsaloranta' at gmail).
Apologies for the hassle, but this is a one-time thing to get through.

Great thanks, I have sent you an email with the CLA attached.

Hmmh. There is one problem here -- core project is not to depend on anything JAXB, including annotations, as that would add a new dependency to the project. I'll have to think about the best way to handle this: ideally the whole JSON Schema generation would be a module and not implemented by core package, but it's bit late for that (nor is obvious how this could even be done).

Btw, thanks on CLA; I added it in repo.

[rawlingsj]

Ok, I think we have found an alternative solution using Annotation Introspector. This pull request can be closed and I will create a new fork for jackson-databind and jackson-module-jaxb-annotations.

[rawlingsj]

By the way, many thanks on the quick feedback.

[cowtowncoder]

Perfect, will have a look at the other request(s) then
