I'm using the soa 5.0 (from JBoss you mean, right?) dist. You didn't give me any Map imports for the WADLAction class, but what I'm using is this:
import org.jboss.resteasy.util.CaseInsensitiveMap;
the code looks like this, I'm about to try running it:
...
CaseInsensitiveMap queryParamterMap = new CaseInsensitiveMap();
queryParamterMap.putSingle("action", "getprofile");
queryParamterMap.putSingle("busta", "27184283");
response = JerseyClientSingleton.get (endpointUrl
,queryParamterMap
,method
,""
);
The "" is the request body, and "method" is a String parameter set to "GET"... I'll let ya know how it goes in a minute... (but feel free to correct me on anything that needs it...)
