JavaMapScript - PostGIS

[Patricia Maria Pereira]

Hello...
 
I need to access PostGIS with JavaMapScript. 
Do I need to do something especial? Do I need a JDBC driver?
 
I tried it:
 
.....
.....
public static void main(String[] args) throws IOException{
 try{
         System.loadLibrary("mapscript");
 } catch(Exception e){ 
        e.printStackTrace();
 }
  mapObj mapa;
  mapa = new mapObj("wms.map");
  imageObj imagem = mapa.draw();
  imagem.save("/l/home0/pat/testePati.jpg");
}
.....
.....
 
But mapa.draw() returns null.
 
My mapfile (wms.map) seems to be Ok, because I get map via cgi-bin with no problems. 
 
Can somebody help me?
 
Thanks in advance...
