<h:commandlink>             <p:graphicimage value="/images/icon/pdf.jpg" />             <p:dataexporter type="pdf" target="mydata" filename="mypdf" preprocessor="#{yourbean.yourpreprocfunction}" />         </h:commandlink>

your preprocess function sould like,

        public void yourpreprocfunction(object document) throws ioexception, badelementexception, documentexception{     document pdf = (document) document; servletcontext servletcontext = (serveletcontext) facescontext.getcurrentinstance().getexternalcontext().getcontext(); string logo = serveletcontext.getrealpath("")+file.separator+"images"+file.separator+"mellatlogo.png"; pdf.add(image.getinstance(logo));      }
