Hello there,

I'm creating a purchase ordering app for my company, but I'm getting
an HTTP 500 error.

Seems like that your class "com.neanyinc.logistics.PMF" is not on your server's classpath which basically means its not in your generated .war file (in WEB-INF/classes or in WEB-INF/lib inside a different library jar). So you should check this.
