QueryParam in Errai JAXRS

[nikhilraj]

Hi

I am trying to invoke the REST service shown below using Errai (2.3.2.Final) via Injection of a caller proxy

     @GET
    @Path("/data.json")
    public Response getJson(@QueryParam("id") List<String> idList);

However, when I pass in a list of Strings containing [abc, xyz], Errai tries to hit the service using the URL '.../data.json?id=[abc, xyz]' instead of '.../data.json?id=abc&id=xyz'.

Is this a bug or am I missing something here?

Hi!

No, you're not missing something. I've missed to implement/test this feature. Here's the JIRA:

[ERRAI-673] Errai JAX-RS does not support List/Set/SortedSet as resource method parameters - JBoss Issue Tracker

If you want to take a stab at it and send a pull request you're more than welcome. We'll try to implement it for the next release (~ Dec. 10).

Thanks,

Christian

This should work now with the latest 3.0- and 2.4.3-SNAPSHOTs.

Cheers,

Thanks Christian!

Unfortunately, I am unable to test the fix as I get the compilation errors given below when I try to use 2.4.3-SNAPSHOT

Could you please point me in the right direction here?

Thanks for testing this so quickly. The fix caused the interceptor code generation to fail. I published new SNAPSHOTs now. Can you give this another try?

Thanks,

Christian

Thanks a lot Christian!

It works like a charm now.
