Hi Umberto,
Sorry, forgot to reply to the list, this time I remember ;-)
This was my configure String for mapserver 4.6.0:
./configure --with-tiff=/usr/local/mslibs --with-jpeg=/usr/local/mslibs
--with-png --with-proj=/usr/local/mslibs --with-wmsclient
--with-postgis=/usr/local/pgsql/bin/pg_config --with-php=../../php-4.3.8
--with-python --with-freetype --with-gd=/usr/local/mslibs --with-tcl
--with-threads=-lpthread --with-wfs --with-wfsclient --with-wcs
--with-gdal=/usr/local/mslibs/bin/gdal-config
--with-ogr=/usr/local/mslibs/bin/gdal-config --enable-debug
--with-httpd=/usr/sbin/httpd2-prefork
--with-oraclespatial=/opt/oracle/product/9.2.0
--with-geos=/usr/local/mslibs/bin/geos-config
Thanks for the tip that library load is done by mapscript.jar.
Mit freundlichen Gruessen/Kind regards
