Ciao Roope,
I would suggest to set up a JNDI datasource and then connect to it with a 
proper datastore.properties as explained here:

[Geoserver-users] SQL Plug-in Assistance

[Kenny Ratliff]

I'm just learning about the GeoServer project and tools.  I've loaded
GeoServer 2.2 and am trying to add the SQL plug-in using the supplied
instructions.  I'm pretty certain I've dropped the jar and dll files in the
appropriate folder.  However, I've stopped/started/restarted the service,
restarted the computer, but cannot get SQL as an option when adding a New
Store.  Can someone advise what I am missing?



Thanks,
Kenny

[Geoserver-users] Use image pyramids plug-in or raster tables in PostGIS v2

[Paul Meems]

I have a test server (Ubuntu) with GeoServer 2.1 and PostGIS v1.5
I also have a large aerial photo in ECW format.
I've converted this ECW file to GeoTIFF and used gdal_retile to create
tiles.
I use the pyramid plug-in to show the data.

Today I have created a second server with GeoServer 2.2 and PostGIS v2.
I've been reading about the new raster tables and I wonder if I should
continue with using the pyramid plug-in or that I should put the tiles (or
even the single GeoTiff) in PostGIS.

Does anybody have any experience, suggestions, opinions or remarks about
this?

Thanks,

Paul

-->java.lang.OutOfMemoryError: PermGen space

The error is due to the large number of classes GeoServer loads,
you have to setup your container to allow for a larger permgen,
see the parameter here:

http://docs.geoserver.org/stable/en/user/production/container.html#optimize-your-jvm

To be clear, it has nothing to do with the amount of data you load,
it's just related to how much functionality you end up using.

Andrea

Re: [Geoserver-users] CAS authentication for early adopters

[christian . mueller]

Hi all, this is a long mail, TOC first

I) early adopters
II) configuration
III) discussion about the authentication entry point


I) Until now, I know about three early adopters

sonya.dow...@dpipwe.tas.gov.au
bre...@craig.fr
gmi...@library.berkeley.edu

I will send you a private mail with a zip file attached. This zip file  
contains 3 jar files which you have to put into the WEB-INF/lib folder  
of your GeoServer installation.


II) Configuration

The CAS authentication filter is able to validate proxy and service tickets.

Configuration options:

1) Name (mandatory)
The name of the filter


2) CAS Server URL (mandatory)

The URL including the context root of the CAS server. This should be  
an HTTPS URL, otherwise users will be prompted for their credentials  
for each new service ticket. (No Single Sign on )

3) No single sign on
This option makes sense if 2) is an HTTPS URL. Activating this option  
will prompt users for credentals each time a ticket is needed. The  
normal mode of operation is disabling this option and use HTTPS as  
described in 2)

4) Proxy callback URL

Only needed if GeoServer itself needs to generate a proxy ticket. This  
is not used at the moment, leave this field blank. For Geoserver  
custom extensions generating proxy tickts, this field must be filled  
with the URL of Geoserver including the context root. The CAS server  
will send reqeusts to GeoServer. This URL must use HTTPS.

5) Create HTTP Session

Basically, there are 2 modes of operations

a) Disallow HTTP session creation

For each request, the client has to include a ticket parameter which  
can be validated by cas server
Example request:

http://mygeoserver/wms?request=getCapabilites&ticket=ST-abadsd

Next request

http://mygeoserver/wms?request=getMap&ticket=ST-efdafd&bbox=...

Normally, a CAS ticket may be validated only once. As a consequence,  
there are 2 additional requests to the CAS server for each Geoserver  
request.

b) Allow HTTP session creation

In this scenario, the client sends the  ticket only once.
Example request

http://mygeoserver/wms?request=getCapabilites&ticket=ST-abadsd

The clients gets back a session cookie called JSESSIONID. For future  
requests, the client has to include this cookie, no CAS ticket needed.  
(For clients running in a browser, the cookie is included automatically)

http://mygeoserver/wms?request=getMap&bbox=...

No further requests to the CAS server are necessary, but an HTTP  
session was created for stateless services.

6) Role Source

Determines where to look for the roles of the user.

a) request header
The name of the request header attribue has to be specified. The  
client has to send the roles of the user as String delimted by ";".

b) User group service.
This is the standard role source.

c) Role service
Used if a special role service was created for the CAS authentication.


After configuring the CAS authentication filter, add this filter to  
the default filter chain. For testing, you could remove the basic auth  
filter.


III) Authentication Entry Point

Here I am not sure about a good solution. What happens if GeoServer  
receives a request without a session cookie and without a "ticket"  
parameter. At the moment, HTTP response code 401 (not authorized) is  
returned. This is nice for application clients doing proxy  
authentication, it is not nice for clients running in a browser.  
Clients in a browser have to contact the CAS server first for a valid  
ticket.

Another possibility is to work with HTTP redirects. This is nice for  
browser applications, since a request without a ticket is redirected  
to the CAS server and after a successful login, the browser is  
redirected to the original request. But this is not nice for  
applications clients doing proxy authentications getting back and HTML  
form.

IMHO, this problem is not resolvable, the only idea I have is to make  
the redirect the standard and if a client wants a 401 response, it has  
to send an additional http parameter like NOCASREDIRECT=true.

Opinions ?

Cheers
Christian

Re: [Geoserver-users] GeoServer 2.2 GDAL plugin ECW support

[Rahkonen Jukka]

Hi,

There can be a memory leak, but one feature of ECW SDK 3.x code is that it is 
caching some data from the last visited areas and caching can't be turned off. 
For sure a good feature for interactive use of a map but totally useless for 
you when you are seeding the tilecache. You can see the effect by opening a 
biggish ECW image with any SDK 3.x based viewer, like ER Viewer, and doing a 
lot of panning and zooming. The memory reservation increases rather high. If 
you do not do anything the memory is freed after exactly 10 minutes if I 
remember right. This is just nice to know, you cannot cure it because the 
reason in in the closed ECW SDK code and 3.x version is old will not be fixed. 
However, many open source projects stick with version 3.x because license 
allows redistributing the dlls but 4.x license does not.

I believe that those packages are compiled with ECW SDK 3.3, based on the 
information from
http://www.gisinternals.com/sdk/PackageInfo.aspx?file=release-1600-x64-gdal-mapserver.zip

Information may be old, though. If you want to know for sure, send mail to 
Tamas and ask. Problem with v. 4.2 is that ECW binaries cannot be delivered 
with the code because of the license, but every user must dowload them by 
himself from Erdas.

Some more reading about GDAL and ECW is here 
http://trac.osgeo.org/osgeo4w/wiki/pkg-gdal-ecw

You may want to have a try by converting ECW images to tiled JPEG-in-tiff 
images with GDAL. Image size is about the same as with ECW, difference in 
quality is not huge and license problems are gone for ever. Commands to use 
(adapt parameters to suit your imagery):

gdal_translate -of GTiff -co tiled=yes  -co compress=jpeg -co photometric=YCBCR 
input.ecw output.tif

gdaladdo -r average  --config COMPRESS_OVERVIEW JPEG --config 
PHOTOMETRIC_OVERVIEW YCBCR  output.tif 2 4 8 16 32 64

Re: [Geoserver-users] GeoServer 2.2 GDAL plugin ECW support

[Björn Harrtell]

Thanks. I did find 3.3 dlls (actually yanked them from the FWTools package)
which enabled ECW with the GDAL plugin...

What I want to do is actually to create a tilecache from this ECW using
GeoServer then remove it so it's never actually served to any user which I
think is acceptable by the license... but seeding the cache results in
GeoServer out of heap memory rather quickly so in the end I resorted to
converting the ECW to GeoTIFF using GDAL as you suggested. Seeding from the
GeoTIFF is rock solid, so I think there is memory leaks going on using
GDAL/ECW and GeoServer.

http://www.gisinternals.com/sdk/PackageInfo.aspx?file=release-1600-x64-gdal-mapserver.zip

Information may be old, though. If you want to know for sure, send mail to 
Tamas and ask. Problem with v. 4.2 is that ECW binaries cannot be delivered 
with the code because of the license, but every user must dowload them by 
himself from Erdas.

Some more reading about GDAL and ECW is here 
http://trac.osgeo.org/osgeo4w/wiki/pkg-gdal-ecw

You may want to have a try by converting ECW images to tiled JPEG-in-tiff 
images with GDAL. Image size is about the same as with ECW, difference in 
quality is not huge and license problems are gone for ever. Commands to use 
(adapt parameters to suit your imagery):

gdal_translate -of GTiff -co tiled=yes  -co compress=jpeg -co photometric=YCBCR 
input.ecw output.tif

gdaladdo -r average  --config COMPRESS_OVERVIEW JPEG --config 
PHOTOMETRIC_OVERVIEW YCBCR  output.tif 2 4 8 16 32 64

Supposing you have purchased an ECW license (which is mandatory to use it
in a Server), the imageio-ext 1.1.4 plugin deals with ECW SDK 3.3.
We didn't test it with more recent version of it, yet.

I think you could try with a more recent version of GDAL (we did some test
with 1.8.1 and 1.9.x) which may support that ECW version.
Latest GDAL native libraries are available there:
http://www.gisinternals.com/sdk/

I see they have also provided some ECW plugin installer (I have never tried
them. They could be useful for your needs).
Please, let us know.

Daniele
