Re: [Geotools-gt2-users] NoSuchAuthorityCodeException when parsing single-polygon GML

[Jody G. <jod...@gm...>]

Nobody got back to you on this?

The problem is the srsName for your second snippit of xml:

srsName="SDO:8265"

The srsName represents the spatial reference name and is usually of the
format "standard":"code". Most often this is some form of "EPSG":"code" such
as EPSG:4326.

In this case your web service is referencing a standards body we don't know
about in geotools - namely "SDO".

I happen to know that SDO is the name of the spatial objects inside an
oracle database; is there a chance the web service you are talking to is
backed by oracle?
