Description

Currently, when using Burlap + Grails, Grails throws a lot of exceptions, probably because of the way Grails handles requests: my assumption is that Grails "thinks" it's an XML request which it can handle itself. Grails is partially right: it is an XML request, but it's not meant for the normal request/response processing. The documentation: at http://grails.org/Remoting+Plugin speaks of a URL mapping in previous versions of Grails (<0.5), but it seems the problem also occurs in the current version of Grails (1.0.3).

I've attached a different testproject: it exposes a simple service through hessian and burlap. They both work, but the Burlap version throws a lot of stacktraces (see below).

Isn't the solution here to use url mappings to isolate your regular controllers from your burlap services? If we were to change this it might break other things like REST supprot

Hi Graeme,

As I understand correctly, the Remoting plugin should just do that. It does the same for httpinvoker, hessian and probably rmi: it creates url's like http://localhost:8080/<context>/<remoting protocol>/<service name>, eg http://locahost:8080/test-app/burlap/SomeService. However, for some reason it doesn't work when using burlap (it does work for hessian, which is a binary protocol), and the above stacktrace will show.

Adding UrlMappings would IMO be fine, but I think it should be part of the plugin then. What I did was to try to copy the documentation on the plugin page, and create an UrlMapping like:

"/burlap/$controller/$action?/$id?"{
constraints { // apply constraints here }
}

But I assume that this syntax is quite incorrect, since it involves controllers and all.

OK, I see the problem is described here:

http://jira.springframework.org/browse/SPR-4542

Somehow I need to either modify the GrailsExceptionResolver or disable it for the remoting plugin.

I disabled the exception resolvers for the dispatcher servlet and that cleans up the output dramatically. No more stack traces!
