Folkds,
correct me if I'm wrong, but it seems GeoServer doesn't handle well
the labeling of multi-polygons, since no label is shown when it
encounters such a polygon (simple polygons' labels are shown
correctly).
Is it a known issue (though I haven't found it on Jire) ?
Best regards,

hmm, I think an appropriate result should be that the label appears in the middle of all the polygons contained in the multi polygon, or worst case, in the middle of one of them. Having no label isn't a good thing I would think.
I don't remember seeing it in Jira, so feel free to add it as a bug as I think it should be labeling at least something. I will take a look at the spec later and see what it says about multi polygons.

Luca,
are you sure the labels are not shown just because there would
be overlapping otherwise? What happens if you reduce the font size
or zoom in?
I'm playing with a shapefile that has multipolygons with more than
1 polyon (downloaded from here: http://aprsworld.net/gisdata/world/)
and labeling seems to work fine?
Cheers

No I'm not sure, just yesterday I've converted multi-polygons to simple ones and some labels were still not shown.
I definitively have to look deeper into it.

Hmm... my datasource is different though (DB2 Spatial Extender).

Strange... maybe you have an issue with the SLD file?
Any error message during rendering? Yesterday I committed a patch
on trunk that should allow for better error messages (that is, with
stack traces).

I know, but I don't have time to install DB2 with spatial extender now.
If the issue it's in the renderer, you'll see it with other data sources
as well.

We could take a look at the SLD file and see what might be going wrong, if you can share it with us.

Indeed wrong it was: my apologies.
Funny though, the labels weren't shown just on multi-polygons, which by mere chance were the ones having that particular value that wasn't covered by my SLD.
I'll close the issue in JIRA.
