Assuming that your script is:
------------ cut ----
CLASSPATH=.:/usr/local/jdk/lib/tools.jar:/home/sam/tomcat/lib/servlet.jar
export CLASSPATH
-------------cut ---

(no #!/bin/sh)

and that it is called: my_env

you can use it to set your env under Bourne type shell by sourcing the
script, i.e., by executing: 

. my_env

Notice the dot and space and my_env. Executing my_env as, say, 
   ./my_env
would set up the environment variable for the shell which is forked for
the script (i.e., a child of your login shell). This shell terminates,
as soon as the script terminates, i.e., the scripts sets environment
variable for itself, and then exits -- not what you want to do.
