I have recently undertaken a project at work to get more familiar with Java. The program uses JSP (input and display only) to implement Beans (request scope) that will (eventually) access a Informix DB. The information input via the JSPs will also be used to populate a PDF form most likely using the FDF apis. This creates are file on a hard drive that will be downloadable. Is there any issues that I will need to be aware of? Will I have syncronization issues with the DB or FDFs unless I do something specific? Any advice would be welcomed. Thanks in advance.
