Web Fragment
Web-fragment.xml was added to Servlet 3.0 to enhance the pluggability of
imported library JARs. The content of web.xml and web-fragment.xml are almost
the same. However, now we can define the configuration information of JARs
with web-fragment.xml and then conveniently plug it into a deployment
descriptor file.
Description of Example
This example defines a filter in a JAR with a web-fragment.xml file. The
filter is configured to obtain and print parameters from a servlet request.
When deploying this application, a parameter is used to choose whether to
import the JAR that includes the filter. Users can then see the function of
the filter, with or without the JAR file.
