SwitchYard RESTEasy Binding with multiple Get Parameters (Strings)

[yusufb]

SwitchYard has a helpful RESTEasy binding which allows you to map a RESTFul implementation (RESTEasy) to a SwitchYard service. The RESTEasy Resource Interface is simply annotated with JAX-RS annotations, and is registered as a rest binding in the switchyard.xml file.

The standard for RESTFul Get method requests is to use 0 or more HTTP Request parameters. Operations on the SwitchYard service interface are however limited to only one input parameter. The problem seems to be that the RESTEasy Resource Interface must conform to the SwitchYard service interface structure, and the operations on the RESTEasy interface are therefore also limited to only one input parameter. Is this correct, or am I missing something?

Thanks,

Yusuf.

Hi Yusuf,

Your understanding is correct. We are planning to add support for multiple parameters in the future, if there is a pressing need to do so.

Hi,

in the meantime, is there another way of doing this?

I have a RESTful service structured like this:

/{environment}/{resource}

which would typically map to something like this in JAX-RS:

@Path("{environment}/{resource}")

public ResponseClass getResource(@PathParam("environment") String environment, @PathParam("resource") String resource) throws Exception;

This is not doable in SwitchYard.

Would the solution be to use a wrapper object as the request payload and store the parameters there?

The bottom line at this point is that you can only have a single parameter in your JAX-RS interface.  That said, we definitely need to support multiple parameters on the JAX-RS interface, since that's a common enough implementation practice.  I will note that this is distinct from supporting multiple parameters on SY interfaces, which is not necessary for this to work.  I have filed the following JIRA to track this:

https://issues.jboss.org/browse/SWITCHYARD-1307

To summarize what's in the JIRA, you should be able to use multiple parameters in the JAX-RS inteface and then use a custom message composer to handle the assembly of those individual parameters into a single object (e.g. a "wrapper" object).

Hi,anybody has resolve this issue on SY?

The url form /{environment}/{resource}??

Thanks in advance

Hi Rory,

It is fixed. Have you seen the rest-binding sample here:
