#35919 — generic rest-api

Hello,

I'm writing a framework which should be also accessable with a webservice. At the moment I'm using Jetty for the server. I have got a set of objects and each object should be defined as a webservice with a REST-API which returns the object as a JSON structure.

I need a call like http://server/"any path"/object_identifier/state which returns the current state of the object (I can get these information by calling a method).
And also I need for each method in the object a call like http://server/"any path"/object_identifier/methodname
The best case should be an automatically generation of all this URLs.

Is there any componente or framework to create a structure like this and is also portable to Tomcat, Jetty and Glassfish? I'm knowing Jersy, but I think I need some wrapper code around to do this.

Thanks 
Phil

Most likely any solution will be portable among any Java web container.

The standard way is using JAX-RS.

I believe that Spring has its own non-standard thing.

http://server/"any path"/object_identifier/state is easy
as it is just a normal RESTful GET request.

http://server/"any path"/object_identifier/methodname is
tricky because it is not RESTful but RPC style.

RESTful only have resources and GET, POST, PUT and DELETE.

Yes, you should use a JAX-RS implementation. There are many of them, 
however. These links (one for Apache CXF, the other for Jersey/Jackson) 
were useful to me:

Hello,

I have tested Jersey/Jackson and this is a good choice for me. In my case I need POST / GET and hopefully PUT and DELETE, but at the moment POST / GET are enough

Thanks for both answers.
