To display file inside a jar:

First, locate the file inside the jar

$> jar tf artifact.jar | grep "web.xml"
webroot/WEB-INF/web.xml

Then use unzip (with -p option)

$> unzip -p artifact.jar webroot/WEB-INF/web.xml | less

Or in one command

$> jar tf artifact.jar | grep "web.xml" | xargs unzip -p artifact.jar
# or
$> unzip -p artifact.jar $(jar tf artifact.jar | grep "web.xml")

Note: unzip option -p:  extract files to pipe, no messages
