Packaging a Servlet into a WAR File
Problem
You have a servlet and other web resources, and want to package them into a single file for deploying to the server.
Solution
Use jar to make a web archive (WAR) file.
Discussion
Servlets are server-side components for use in web servers, and are discussed in Chapter 18. They can be packaged for easy installation into a web server. A web application in the Servlet API specification is a collection of HTML and/or JSP pages, servlets, and other resources. A typical directory structure might include the following:
-
index.html, foo.jsp Web pages
-
WEB-INF Server directory
-
WEB-INF/web.xml Descriptor
-
WEB-INF/classes Directory for servlets and any classes used by them or by JSP
-
WEB-INF/lib Directory for any JAR files of classes needed by classes in the WEB-INF/classes directory
Once you have prepared the files in this way, you just package them up with jar :
jar cvf MyWebApp.war .
You then deploy the resulting WAR file into your web server. For details on this, consult the web server documentation.
