Cannot re-create layer after deletion

I think this is rather a geoserver rest api bug, but i will start here…

i create a layer through the geoserver-manager and it works great (thx for the previous fix!)

next, when i delete the existing geoserver layer with

publisher.removeLayer(GEOSERVER_WORKSPACE, layerName);

the rest api log says:

07 Nov 15:04:27 INFO [org.geoserver.catalog.rest] - DELETE layer misu8:t1008

and returns 200 - OK (the store and layer name is good). the layer is not shown in the geoserver web interface.

but when i send in the same create call to re-create the same layer, i get an exception:

07 Nov 15:04:27 INFO [org.geoserver.catalog.rest] - DELETE layer misu8:t1008
07 Nov 15:04:27 INFO [org.geoserver] - Loaded feature type 't1008', enabled

what am i doing wrong, should i delete something else to wipe out the layer definition?

thx

the configuration: geoserver-manager : geosolutions-it-geoserver-manager-v1.4.2-22-gfc4251f.zip (the branch with the fix for https://github.com/geosolutions-it/geoserver-manager/issues/45) geoserver: 2.2 (had to upgrade it since the last bug)

You should not use

publisher.removeLayer(GEOSERVER_WORKSPACE, layerName);

In geoserver, they are 2 different resources associated to a GIS web-layer, but the name of methods can lead to a misunderstanding. The different resources are:

• the layer
• the featureType

When you do you publishDBLayer, you publish both. When you do removeLayer you just remove the layer resource, not the featureType.

So to answer to your questions is there a way to completely remove a layer from the geoserver?

Yes, there is, using unpublishFeatureType instead of removeLayer. Again, the first unpublishes everything, the latter remove only layer part (that’s why you get an error)

Old comment, but I found the possible solution…

Just call publisher.reload(), after your delete the layer to regenerate the geoserver catalog…
