title: How do I incrementally patch a war file
body: <p>I am having war file deployment at customer site. War file contains lib folder which contains dependent jars e.g.</p>
  
  <p>/lib/app-01.jar
  /lib/spring-2.5.1.jar
  /lib/somefile-1.2.jar
  ...
  ...</p>
  
  <p>If we need to update lets say app-01.jar to app-02.jar, is there any elegant solution? how does these dependent jars are packaged into WAR file as industry standard? </p>
  
  <p>Is it good idea to package those dependent jars without version number?
  e.g.</p>
  
  <p>/lib/app.jar
  /lib/spring.jar
  /lib/somefile.jar
  ...
  ...</p>
  
  <p>EDIT NOTE:
  Actually, War is deployed to Webshpere, WebLogic, Tomcat on Windows or Linux platform. And Customer's IT department is involved for deployment</p>
