Web based Java application PDF reports. Add option for additional PDF report formats to existing app. - repost 3

We have an existing web based java application that creates PDF patient reports that contain laboratory results. A customer has requested additional formats of the PDF reports. Need developer to add functionality to the application to specify a System Wide PDF format template as well as a Customer specific PDF format template. Also add the framework to be able to add additional PDF templates in the future. There are various portions of the application where the PDF template format is used. These must all be taken into account Current application has option for custom file naming. Need additional file name variables.
