[Mapserver-users] MapScript and Servlet

[Umberto Nicoletti]

Try copying mapscript.so in /lib or a patch that ld knows
(/etc/ld.so.conf) and then run ldconfig.

If even that does not work export
LD_LIBRARY_PATH=/path/to/dir/containining/mapscript

before starting tomcat.

The tomcat-user mailing list has some good threads on this issue:

You are running the servlet from Tomcat, aren't you?
HTH,
Umberto
