Hi,

We have developped JSR-303 support for JFace Databinding Validators (this link explains how to use it) that we have the intention to use in our Eclipse RAP/RCP application. If you don't know JSR-303, the basic idea is set to your constraint validation with annotation:

public class Person {
...
	@Size(min = 1)
	private String name;

	@Size(min = 1)
	@Pattern(regexp = ".+@.+\\.[a-z]+")
	private String email;
...
}

For instance Hibernate can use those annotation when Person must be saved in the DB to check the validity of the Pojo.Our JSR-303 support for JFace Databinding Validators implements a IValidator which uses those annotation with JSR-303 API ValidatorFactory. It works too in OSGi context and we have developped several OSGi fragments and OSGi bundles (to change for instance at runtime the JSR-303 Implementation).

I would like do more test and create a patch to contribute to Eclipse.
Hope you will like it.

Regards Angelo

Hi,

Just for your information we are using the JSR-303 support for JFace Databinding in our RAP demo at http://xdocreport-rap.opensagres.cloudbees.net/xdocreport?startup=fr.opensagres.xdocreport.eclipse.application

For instance if you edit a resume and you fill email with bad value, you will have errors displayed in the editor (see attached screen) :

Hey Angelo,

This is looking really good! Definitely looking forward to your patch!

There's been some prior work done on bug 279166 [1], so when you're
ready feel free to attach your patch there.
