[Geotools-gt2-users] getting a ysld symbol from geoserver
|
From: RIOU Y. PP-D. S. <yva...@in...> - 2023-09-21 14:20:32

Good evening,
First, I would like to thank you a lot for your hard work to offer us
such an impressive API !
I'm new to Geotools and Java coding too so I apology for my question .
I'm trying to display a wfs layer that was published in Geoserver within
a MapContent (org.geotools.map.MapContent).
For the symbology's wfs layer , i'm trying to parse a ysld file also
stored in GeoServer and queried via the rest interface.
But , I'm not able to correctly parse the file into a
StyleLayerDescriptor object for further rendering.
I'd be very grateful if a skilled guru would tell me what's wrong with
my bad coding.
I tried to add a newline , a tab , a space between each line read in
inputLine but the result is always the same error : /Unable to turn ...
into reader/
/while ((inputLine = in.readLine()) != null) {//
// response.append(inputLine);
// ///response.append('\n');///// }
/Here is the ysld file content , the java class, the pom.xml and the
errors reported :
/----------------------------------------------------------------------------------------------------------------------------------------------------------------//
//gare.ysld :
//title: gare//
//symbolizers://
//- point://
// size: 4//
// symbols://
// - mark://
// shape: circle//
// fill-color: '#ff00ff'//
