I need to generate a PDF(Invoice) via XSLT File. I have a XML file which contains our data. I have to use this xml and customer's xslt file for generate our PDF. Problem is I never do this kind of thing before. Is there any workaround, Basic Tutorial or any helpful document? If there is some it would be really helpful. I made some search and I found Apache FOP(2.5) but I can't use that because there is an error.
