java - Show jasper report HTML page (web app) in Spring roo aplication -
i'm novice spring roo.
with spring roo created application. when use webapp example in spring roo results pdf, word, .... html , "html page page viewer" not work. when change html , "html page page viewer" hello world, appear correct. jsp pages correctly declared. further not error.
with webapp example code of jasperreports library outside of spring roo application desired results, when use same jsp file in spring roo application empty screen.
in jsp check jasperprint object not empty , can see has 10 pages. system.out.println("aantal pagina's = " + jasperprint.getpages().size());
in fileuploadcontroller set session attributes. start message.jsp file. message.jsp file export page in jasperreports webapp example. message.jsp file show correctly. also, pdf, word etc. links work correctly , see correct pdf representation of jasper report. first 2 links, html , html viewer page page not show correctly. html page empty. when change page "hello world" shows correctly.
in spring roo have fileupload entity. in fileuploadcontroller added:
@requestmapping(method = requestmethod.post, produces = "text/html") public string create(@valid fileupload fileupload, bindingresult bindingresult, model uimodel, httpservletrequest httpservletrequest) throws urlnotfoundexception { if (bindingresult.haserrors()) { populateeditform(uimodel, fileupload); return "fileuploads/create"; } file file = null; uimodel.asmap().clear(); commonsmultipartfile image = fileupload.getimage(); if (image != null) { file = new file(image.getoriginalfilename()); system.out.println("original filename = " + image.getoriginalfilename()); try { image.transferto(file); fileupload.setcontenttype(image.getcontenttype()); fileupload.setpath(file.getabsolutepath()); fileupload.setremoteurl(httpservletrequest.getremoteaddr()); } catch (exception e) { e.printstacktrace(); return "fileuploads/create"; } } file jrprintfile = file; jasperprint jasperprint = null; try { jasperprint = (jasperprint)jrloader.loadobject(jrprintfile); } catch (jrexception e) { // todo auto-generated catch block e.printstacktrace(); } httpservletrequest.getsession().setattribute(basehttpservlet.default_jasper_print_session_attribute, jasperprint); httpservletrequest.getsession().setattribute(imageservlet.default_jasper_print_session_attribute, jasperprint); httpservletrequest.setattribute("filepath", file.getabsolutepath()); httpservletrequest.setattribute("message", "the report " + image.getoriginalfilename() + "has been done successfully!"); fileupload.persist(); return "fileuploads/message"; // return "redirect:/fileuploads/" + encodeurlpathsegment(fileupload.getid().tostring(), httpservletrequest); } } my message.jsp file (like export page in jasperreports webapp example)
