Create Dynamic Invoices Using Crystal Report and Java

I need to create PDF invoices created dynamically from Java and crystal Report. The Program will be a service that will be running 24/7.
The program should create QR images from the fields and send the image to crystal report dynamically
This service will take the invoice fields from a text file and send them to crystal reports to print as pdf and send it to printer.
The text document will be tab delimited with fields such as company name , company email , products, etc..
