Adding Web Beans JSR 299 to Jersey for REST

While playing with Web Beans I thought it would be nice to add Web Beans support to Jersey. Jersey is a JSR 311 implementation for RESTful web services in Java. Though it has taken some flak, I – and others – think it’s easy to use. Because it’s easy in Jersey to control the creation of objects by writing your own servlet with a Jersey ComponentProvider, I finished a quick hack in no time. Some help was the integration examples for Spring.

Having defined this servlet, a REST resource example for the UuidService from my last post about Web Beans, looks like this

Works like a charm. The UUIDService is injected through Web Beans and the scopes from Web Beans, @RequestScope and @SessionScope seem to work. This takes a big burden from the developer.

I hope to implement a SOFEA web application with Javascript parts which communicate with the backend via REST. For performance reasons it would be nice to populate and render the Javascript on the server. Therefore I would wish I could resolve REST calls to Jersey internally like

to pre-populate pages with REST calls in them.

Thanks for listening.

Update:The Jersey lead wrote about a Jersey client API which perhaps does what I want. Splendid.
