Enclosing/attaching zip, docx … file to pdf report made in java-jasperreport

Hi guys,

I am developing a report java-jasperreport, and the layout that was given to me, says I need to create a button with a file(when clink in the button a file is downloaded) this file can be basically zip, tar, xml, xsl,,,

I would like to know whether would be possible to enclose a file(inputstrem) to a pdf generated by jasper, so when I click in the button it would be downloaded.

The workaround I think I could do would be making the file available to download through http server, or rest service, but I would like to do it in an offline mode.
