[Geoserver-users] LayerGroup creation from REST Configruation

Justin,

If that's so, I get an HTTP 500 from Geoserver 1.7.3 when I perform the
following HTTP query:

From the Geoserver logs:

Do I smell yet another bug inside Geoserver??

Hi Ronak,

You have found yet another hole in the docs. I will try to update when i

get a sec. But the quick answer is yes, only the name and the layers are

necessary when posting a layer group. The bounding box is the spatial
extent of the layer group. You can specify a bounding box, but it is not

necessary, it will be calculated automatically if not specified. Usually

the only reason to specify it would be if perhaps one of the layers in
the group is quite big and you want the group to be constrained to a
smaller spatial extent. Like the tiger-ny layer group that comes with
vanilla geoserver configuration.

The styles are optional, if you don't specify them then the default
style for each layer will be used. If you do specify them, then you
specify a style for each layer specified.

Hope that helps.

-Justin

Justin,

I was looking at the LayerGroup REST API Documentation and I see that

it

has a POST API Document:

http://docs.geoserver.org/1.7.4/user/extensions/rest/rest-config-api.htm
l#id8

However, it does not list what are the required parameters for a POST
for a LayerGroup.

I assume I have to pass the name and the list of Layers. Do I need to
specify a bounding box? What is that the bounding box of? How can I
compile that bounding box?

What are the Styles? Do I have to specify those as well?
