Issue with Mapscript in Java

[Jean-Henry Berevoescu]

Most probably you forgot to add mapscript.jar to the CLASSPATH
Also, for the DLL problem you had before, I would recommend
relaying on platform independent mechanisms, i.e. copying the DLL
to a directory one assumes might be in the library loading path is
not a sure bet and it definitely would not apply for any platform -
one should use "-Djava.library.path=..." for this kind of situation.
