simple mapserver instrucctions don't work!!

[Jose Luis Gonzalez]

I am using mapserver 4.2.4.
All I wanted to do is to do any simple mapserver instructions to see that everything works.
I have tried the demos that apear when you install mapserver, but I wanted to see it work with my own code and deploying my archives to the server.
For example it will be great if i could manage to just draw a .map file for instance as a response to the client.
Does anyone know how to do this, or what easy instructions I can use to see if it works?

Thank you

Jose Luis

Jose Luis,

1) it is *very* important that you mention which version of MapServer
you use! The mapscript module has changed very much from 3.6 to 4.4.

2) do not try to use itemObj, it is not functional. We use SWIG to
generate the mapscript wrapper for Java, and it is very permissive,
with the result that non-functional classes can be accidently
added to mapscript. I'm going to shut itemObj out of the final 4.4
release.

cheers,
Sean
