I was trying to execute my servlet without Tomcat or any webserver and I came across this concept of running it with servletrunner.Not a great idea. You're better off grappling with the target execution straight away.
It says it is through JSDK. So is this special development kit I should download or is it part of JDK6?It is or was part of the Java Servlet SDK. I'm not sure it's even available any more.
