public class pdf {     private streamedcontent streamedcontent;     private static final long serialversionuid = 1l;    @postconstruct          public void  createpdf() throws documentexception, ioexception {       try{         document document = new document(pagesize.a4, 50, 50, 50, 50);         outputstream out = new bytearrayoutputstream();         pdfwriter writer = pdfwriter.getinstance(document, out);         document.open();          pdfptable table = new pdfptable(1);         pdfpcell cell = new pdfpcell(new phrase("\u0627\u0644\u0633\u0644\u064a\u0637\u064a"));         cell.setborder(rectangle.no_border);         cell.setrundirection(pdfwriter.run_direction_rtl);         table.addcell(cell);         document.add(table);          document.close();         out.close();          inputstream in =new bytearrayinputstream(((bytearrayoutputstream)out).tobytearray());                      streamedcontent = new defaultstreamedcontent(in, "application/pdf");                 //-------                 map<string, object> session = facescontext.getcurrentinstance().getexternalcontext().getsessionmap();                 byte[] b = (byte[]) session.get("reportbytes");                 if (b != null) {                     streamedcontent = new defaultstreamedcontent(new bytearrayinputstream(b), "application/pdf");                 }                }         catch (exception e) {                 }     }

the itext war file kept under /lib folder , has worked fine. compatible version itext 2.1.7 please refer dependencies in primefaces guide
