What shell are you running this script as?  I assume bash, but set is
not a commonly used function AFAIK. (unset OTOH is commonly used.)

In bash these lines would be 
   export JAVA_HOME=/usr/java/j2sdk1.4.2_06
   export RESIN_HOME=/usr/local/resin
   PATH=$PATH:/usr/java/j2sdk1.4.2_06/bin
to set the environment variables.
The path line works because $PATH is already an environment variable

Your syntax is using 2 built in shell commands -- export & set -- and
you cannot do that in most cases.

The best place for that would be to add a call in /etc/rc.d/init.d/httpd
to start the scripts, or even better to put a custom script there (maybe
named "resin")to start the resin server so init will launch it for you.

If you created your own script there for startup then it would happen
automagically once all the proper magic is in the script.  See other
scripts there to see the format needed, and use the man pages for
chkconfig and service to see the details.
