You can use either the LiveCycle ES Forms' renderPDF service (for XDP based PDFs) and/or the LiveCycle ES Foundations' formDataService (usually used for Acroforms based PDFs or XFA type XML data). Both of these require the LiveCycle ES server products
there must be a way without installing a server. it's just about importing some field data into a pdf. it works for data on a hard disk with ONE line of code. and I quess it is the same with data from a server.
