Java Mapscript Error

[Stephen Jones]

Hi,

Sorry forgot to add all that stuff. Anyway here it is. 

Makefile

/opt/mapserver-4.10.0/configure --without-tiff \
                                --with-threads \
                                --with-proj \
                                --with-gdal \
                                --with-ogr \
                                --with-gd \
                                --with-freetype \
                                --with-curl \
                                --with-wmsclient \
                                --with-wfs \
                                --with-wfsclient \
                                --with-geos \
                                --with-sos

Java
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode)

OS
Linux Fedora Core 6

Servlet Container Oracle 0C4J (Part of JDeveloper)

Have done the same build on Linux CentOS4.3 and get the same error (Servlet Container Apache Tomcat 5.5.20) 

At the moment the onlt geo data source I am using is Shapefiles, and the only output I am returning is either PNG or JPEG.

Cheers S

Please report the mapserver version, how it was built and the
environment (windows/linux, shapefiles, database, ecc).
It is difficult to help you without knowing that.
