Deployment Flow / Process from netBean IDE to tomcat servlet container

[saneha]

Could you please answer the following? I have installed tomcat on D: drive and tested it successfully with new servlet along with welcome.jsp. And I have also installed netBean IDE on C: drive and created my "TestProject1" in the new folder called "MyNewWebProject1" Question is: When we press run button from netBean IDE, what is happening in the back-end? Is netBean IDE generates the XML or JAR/WAR file and deploy on the tomcat servlet container? If yes then how this happens? Which XML file is doing this job? Thanks and kind regards, Waheed Ilyas KSA
