Calling RESTful web services from Mendix

I see in this forum that there are some posts in 2010 saying that calling RESTful web services isn't supported in Modeller. As it's now 2013 have things progressed at all - is there a way to do this without having to resort to Java? As I am not a Java programmer if I need to resort to this can anybody please provide some guidance on what code I'd need to use to issue POST/GET commands with a text/xml payload? Many thanks!
