Tomcat help

[Jean-Henry Berevoescu]

But your error is not related at all to the fact that the JAR file or
classes
archived in it is/are not found.
The error is not ClassNotFound, but UnsatisfiedLinkError and that's
pointing to the fact that one or more the native libraries and/or functions
exported by them are not found (the same error you can get if you use
an old library with a call that is not implemented by it - but we digress
already).

The fact that you set:

export LD_LIBRARY_PATH=/etc/tomcat5/common/lib

and not at least

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/etc/tomcat5/common/lib

means that you actually expect to have all the necessary libraries in that
directory - which is not normally the case for a UNIX platform.

Moreover, as I said, newer approach that considers platform independence
specifically asks for <-Djava.library.path=...> to be set - and it acts, in
principle as LD_LIBRARY_PATH does on UNIX platforms - and that,
in turn, means that you need all the native libraries to have their
paths in that property, not only one of them.

An in a normal case, one would have, say, GDAL in one place,
GD probably in another and so on... It's a bit extreme, I agree,
since the usual scenario is that you will have to add a few dirs
to the search path: /usr/lib, usr/local/lib, some platforms have
/opt/lib, others also /usr/shared/lib and/or /usr/local/shared/lib
and so on.
You will have to check all the dependencies, where they are
located and add the corresponding directories in the search
path.
