[Geoserver-users] Converting CSS to SLD without web interface

GeoServer GeoServer User
1

Hi all,

I'm still experimenting with the great CSS Module and already managed to reproduce major parts of my former SLD styling information with much less code. Many thanks to David Winslow for developing this (also thx for updating the docs on the GeoServer website!)

In order to establish CSS styling in the automated workflow of the company I'm working for, I'm looking for a way to programmatically execute the CSS -> SLD conversion. So far I only managed to do this via the "CSS Demo" web interface by clicking on "Submit".

Is there any other way to access this conversion logic going on behind the scenes?

Thanks in advance and best regards,
Matthias

Yes, but it has been developed mostly for testing use and so isn’t packaged individually. If you have a working GeoServer installation, you should be able to run it after first including the GeoServer WEB-INF/lib directory on your CLASSPATH:

$ java -cp ‘webapps/geoserver/WEB-INF/lib/*’ org.geoscript.geocss.Converter foo.css

For each file argument, the converter will attempt to parse the file as CSS and write the resultant SLD to a file with the same name, but with the file extension replaced with SLD. So it is possible to convert many CSS files in one go and save yourself some JVM startup time.

There is also a Java API which is adapted for use in most (all?) variants of GeoScript (http://geoscript.org/).

Hi,

My web application uses Struts Framework, and the enviroments are JDK 6,Tomcat 6, GeoServer 2.2.2.

I configured GeoServer to secure WMS, a basic authencitation window pops up for WMS request. For example, user name and password
are required to input to access
http://localhost:8080/geoserver/topp/wms?service=WMS&version=1.1.0&request=GetMap&layers=topp:states&styles=&bbox=-124.73142200000001,24.955967,-66.969849,49.371735&width=780&height=330&srs=EPSG:4326&format=application/openlayers
In my web application, I don’t want to pass username and password in the URL string, instead, I want to access the secured WMS without authentication window.
I used ol4jsf proxy but it doesn’t work, the autentication window still pops up.

Please see below for my set up. Is there something wrong?

In my JSP page, I do the WMS request such as these:
untiled = new OpenLayers.Layer.WMS(
“topp:states - Untiled”, “http://localhost:8080/geoserver/topp/wms”,
{
LAYERS: ‘topp:states’,
STYLES: ‘’,
format: format
},
{
singleTile: true,
ratio: 1,
isBaseLayer: true,
yx : {‘EPSG:4326’ : true}
}
);

I put ol4jsf-core-2.5.0.jar in my application WEB-INF/lib floder and create ol4jsf-proxy.xml in WEB-INF/classes:

<?xml version="1.0" encoding="UTF-8"?> Development Environment. http://http:localhost:8080/geoserver/wms admin geoserver

In my web application web.xml page, I added these:

OL4JSFProxy org.ol4jsf.proxy.servlet.OL4JSFProxy 0 OL4JSFProxy /OL4JSFProxy/*

Any suggestions are highly appreciated.
Thanks!

To avoid the popup (challenge) you have to send the Http Header

Authorization

which each request.

Look here for an example

Hi Christian,

Thanks so much for you response. I looked at your example and understood basic authentication, but I don’t know to how to use it with openLayers. Can you please give me an example or guidelines?

I use openLayers to do WMS request as below. How to use basic authentication for this?

…

// setup tiled layer

tiled = new OpenLayers.Layer.WMS(

“Geoserver layers - Tiled”, “http://localhost:8080/geoserver/nc/wms”,

{

LAYERS: ‘NC_Map’,

STYLES: ‘’,

format: format,

tiled: true,

tilesOrigin : map.maxExtent.left + ‘,’ + map.maxExtent.bottom

},

{

buffer: 0,

displayOutsideMaxExtent: true,

isBaseLayer: true,

yx : {‘EPSG:4326’ : true}

}

);

// setup single tiled layer

untiled = new OpenLayers.Layer.WMS(

“Geoserver layers - Untiled”, “http://localhost:8080/geoserver/nc/wms”,

{

LAYERS: ‘NC_Map’,

STYLES: ‘’,

format: format

},

{

singleTile: true,

ratio: 1,

isBaseLayer: true,

yx : {‘EPSG:4326’ : true}

}

);

map.addLayers([untiled, tiled]);

Thanks Christian for the link! It’s helpful!

I figured out how to use OL4JSFProxy to do geoserver WMS authorization with OpenLayers. It worked!

Thanks so much!
