Where are my javaEE programmers?

[gweedo]

So I am working on a project and I have worked with Servlets and JSP using Jetty. It was a torrent tracker. So I know what I am doing.

What is a good server program to run servlets?

What is the difference between TomCat and GlassFish? (Beside one is apache and one is oracle)

What the difference between Tomcat/glassfish and google app engine?

What amount of data would be the required to get the benefits of hadoop?

Should I be using a datastore or mysql?

WOW no javaEE programmers? really come on.

For local server I use tomcat, mysql or postgresql.

I use Google App Engine sometimes for personal projects because its free under a certain quota.  The database is not SQL and hard to use, but it is free.

So what are the benefits of using tomcat vs glassfish or even jetty?

[jimbobway]

I've only used tomcat and jetty.  Not sure what the differences are but for development they work the same.  Most Java shops use Tomcat.   I dont know of anyone that uses Glassfish.
