If you change the type of your item method parameter from String to a collection such as List, you should get a collection that holds all the values you are looking for.

@GET
@Path("/foo")
@Produces("text/plain")
public String methodImCalling(@DefaultValue("All") 
                              @QueryParam(value = "item") 
                              final List item) {
   return "values are " + item;
}

The JAX-RS specification (section 3.2) says the following regarding the @QueryParam annotation:

The following types are supported:

1. Primitive Types
2. Types that have a constructor that accepts a single String argument.
3. Types that have a static method named valueOf with a single String argument.
4. List, Set, or SortedSet where T satisfies 2 or 3 above.
