Exactly.

We'd already "imagine" something like that.

thanks for the info, we were looking at the old oracle code.

The ideal case would be to not need any overrides. At the moment, 
WFSConfiguration does not work with complex features. If this could be 
fixed with changes to the existing bindings, then no additional encoder 
configuration would be required. However, because GeoAPI cannot 
represent complexType-with-simpleContent (app-schema smuggles the simple 
content in a simpleContent property), at least one binding override will 
be required, hence a new configuration.

My aim is to fix existing code as much as possible, and make the new 
configuration as small as possible; in the future it need not exist.

Kind regards,

Re: [Geoserver-devel] GSIP 31 - Use DataAccess API - Revised and Implemented

Indeed; this is a two way conversation.

However with this particular issue I feel we are missing the boat a 
little bit. You have a data structure that can represent an attribute 
with several pieces of formal information already - use it.

You can construct an ComplexAttribute when parsing and reverse the 
process when encoding. A ComplexAttribute holds two required pieces of 
information that you are going to have to give the model a name for (you 
would need to do this if you were drawing a UML diagram of your data 
structure anyways right?).

We can move this discussion to the GeoAPI list if you like; but so far I 
have not been convinced.

Jody
PS. You also have a clientProperties map that can be used to hold 
"informal" information if needed (such has hints to make your 
parser/encoder happy).
PPS. The one valid argument I thought through is XPath support; but I 
have yet to see it presented clearly

Re: [Geoserver-devel] Message bundles for GeoServer extension

Great, thanks Justin. 
Yes, I'm quite familiar with REST and this API looks really useful. I'll
give this path a shot.

Cheers,
Tim

Yeah, I am fairly certain it is not possible to load JSP's from the 
classpath. A few of us have tried :).

Well, you can follow the path maxFeatures takes from the parsing down to 
the datastore, but you'll get no straight path leading to where the
connection is grabbed from the pool, as the API simply does not have it.
The current SQLDialect method to deal with a connection is simply:

public void initializeConnection(Connection cx)

so you have no way whatsoever to know what the query hints were.

If you get stuck you may also consider asking for help by the
GeoServer commercial support providers, they are listed here:

[Geoserver-devel] Compiling Geotools release for Geoserver 1.7.2

I want to try out some local changes to Geotools in Geoserver 1.7.2
but I am confused about which version of Geotools should be used.

Previous releases pointed to a certain version/tag and revision, but
the recent releases mentions just a version/tag. The release notes for
Geoserver 1.7.2
says Geotools 2.5.3 was used but http://svn.geotools.org/tags/2.5.3
does not exist.

Regards,

/Björn Harrtell

[Geoserver-devel] Geoserver 1.7.2/Geotools 2.5.3 Eclipse Project


Hi All,

I'm trying (did it already) to mount a geoserver 1.7.2 project at eclipse.

In the web module, i ran test class and the jetty is running successfully.
The issue is, i use Oracle database, so, in this geoserver (running from
eclipse), the datastore doesn't have "Oracle" option. In a normal situation,
i have to copy ojdbc and gt-oralce-plugin jar files into lib folder. There
is any way i could have the oracle datastore in the geoserver running at
jetty.

As i want to have the oracle source in my project, how can i add some
geotools modules to my geoserver project? If it is possible to run in real
time at jetty?  

At last, i would like to know which modules do i need to add (from geotools)
to my geoserver project so i could change the oracle plugin.

Many thanks.

D.Nunes

Re: [Geoserver-devel] Geoserver 1.7.2/Geotools 2.5.3 Eclipse Project

For oracle, there is a maven profile you can use to load the oracle 
specific modules:

mvn -P oracle-old eclipse:eclipse

However this will only link the binary from the maven repository 
(although you will be able to browse the sources).

If you want to link to the source code directly so that changes you make 
can be realized without running mvn install, you will have to manually 
import the geotools oracle module into your eclipse workspace, and 
manually edit the classpath of the web module to include it.

For this second option to work properly you will have to ensure that you 
run mvn eclipse:eclipse from the oracle module itself, and not from the 
root of the geotools source tree.

I myself prefer the profile approach, and maintain separate eclipse 
workspaces for geotools and geoserver. Linking the sources of both 
projects results in a huge eclipse workpsace and is somewhat tedious.

Never managed to have GeoServer modules depend live on the GeoTools
ones, there are some test dependencies propagating from the
GeoTools modules that make it impossible to startup GeoServer
(unfortunately eclipse does not have a concept of a test vs compile
dependency and propages them all without discrimination).

What I usually do is to create a configuration that uses the oracle
jars:

mvn eclipse:eclipse -Poracle

then reload the geoserver projects in eclipse and eventually fix
the missing oracle driver jar.
