On day 2 of JavaOne 2008 conference, Emmanuel Bernard talked about Bean Validation framework (JSR 303). The goal of this specification is to provide a uniform way to express and implement the constraints in java applications. Earlier in the day, Oracle team previewed the upcoming features of Oracle Fusion Middleware 11g.
Jason Carreira has submitted JSR 303 to standardize a meta-model and and API for JavaBean validation. The JSR has just been submitted and has not yet been approved by the JCP EC, but if approved the API could provide a consistent validation approach across tiers and within other standards and frameworks. InfoQ spok to Jason to find out more about the potential of JSR 303.
