Ok, I've not played with servlets (had no need) but here goes (and
someone correct me if I'm wrong):
Java-Apache is the name of the project to integrate Java with Apache.
JSERV is a web server that embeds java into web pages which is processed
on the server. This is not JavaScript, but similar to PHP or ASP.
Not sure what JSSI is. I have heared of Jakarta & Tomcat, but thats all.

To access postgres from Java, you will need JDBC.

No. There are four types of JDBC driver, and ours is Type 4, which means
its written in pure java, and will run anywhere.
