Adding XML REST to Roo

[faktor]

Hi all,

I just upgraded to the latest roo and love the "json all" addition. I would like to also have a way to do the same thing but return XML rather than a json payload. I also need to create some custom services that return XML.

What is the recommended best practice for getting that into the project without messing up the already supported json views?

Thanks,
Mark

There is an external add-on which installs Springs ContentNegotiatingViewResolver. So you need to search the add-on first:

addon search "Content Negotiating View Resolver"

then install it and use it. Use 'addon info' to see details about its intended usage.

You should use a Roo 1.1.2 snapshot build to do this: http://static.springsource.org/downl...hp?project=ROO

I can't get "Content Negotiating View Resolver" addon to work. Please see errors below.

roo> addon install id --searchResultId 43
Target resource(s):
-------------------
net.tzolov.httprepresentations.roo.addon (1.1.6)

Deploying...done.
