Build Deployment basics

I am more into UI dev and less into Java...So, I would like to understand what exactly does the following things mean; 1. Build Deploy (Is it just a folder coped to a server and if yes, are there only class files in there,...) 2. Wha开发者_如何学Got does exploded build mean?

If someone could explain me in very easy language (and not extremely technical), that would be really great...

Also any online resources in simple language would be helpful..

Thank you.

1. Build Deploy

Build deploy process will include many things such as

a) Checking the server configurations like database configurations, server resources configurations etc.

b) Checking the Application Configurations , means any changes in the application related configuration files.

c) Deplying the code on to the server during this process server will read up the deployment descritor and deploy the application based on the configuration provided in DD xml (web.xml) Also it deploy the ejb modules based on the configuration provided in ejb-jar.xml

1. Build Deploy

   You build your application into some packaging and deploy it on the server.

for example if its web app you pack it in war file and put this war file on the server webapp for tomcat (dir differs from server to server) and start the server to deploy it.
