    Seam with JSF and Jasper Reports

    Tasneem Bhyat Newbie

      Hi
      Could someone please help me with regards to an example or explanation of how to use Jasper Reports with Seam and JSF? I am using iReport to generate my jrxml, I just need to know how to render the report from a jsf in a web app that uses seam.


      Thanking you

          and in your controller output generated pdf file to response output

            Hope it helps :)


            InputStream reportTemplate = this.getClass().getClassLoader().getResourceAsStream("quote_orderform.jrxml");
            Map<String, Object> parameters = new HashMap<String, Object>();
            // parameters.put(JRJpaQueryExecuterFactory.PARAMETER_JPA_ENTITY_MANAGER,entityManager);
            
            JasperReport jasperReport;
            JasperPrint jasperPrint;
            JasperDesign jasperDesign;
            
            parameters.put("param_01", "value of your param");
            parameters.put("param_02", "value of your param");
            parameters.put("param_03", "value of your param");
            
            
            byte[] pdf = null;
            
            try {
                 jasperDesign = JRXmlLoader.load(reportTemplate);
                 jasperReport = JasperCompileManager.compileReport(jasperDesign);
                 jasperPrint = JasperFillManager.fillReport(jasperReport,
                 parameters, new JREmptyDataSource());
                 pdf = JasperExportManager.exportReportToPdf(jasperPrint);
            } catch (JRException e) {
                 //handle error
            }
            
            FacesContext context = FacesContext.getCurrentInstance();
            HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();
            
            try {
                 OutputStream os = response.getOutputStream();
                 response.setContentType("application/pdf"); // fill in
                 // contentType
                 response.setContentLength(pdf.length);
                 response.setHeader("Content-disposition", "attachment; filename=\""+ "_nameOFile.pdf\"");
                 os.write(pdf); // fill in bytes
                 os.flush();
                 os.close();
            context.responseComplete();
            } catch (IOException e) {
                 //handle error
            }

              Hi

              Thank-you so much. This is exactly what i was looking for. You are a star!!!! Your help is much appreciated. I have done the above code, but I think there may be something wrong with my classpaths. I ran the code above but am getting
              14:30:15,531 ERROR [application] javax.ejb.EJBTransactionRolledbackException: java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester

              Do you have any ideas what this could be. I have the commons-digester jar in my classpath, but the error is still there...

              Thanking you

                Are you sure that is in your ear-lib ?

                  My solution is pretty much same as Giovannis with two differences. First, I compile my jasper report upfront as opposed to compiling it during runtime. Second, terminate jsf lifecycle by signalling that response is already generated for this request. Of course you also have to make sure you have the missing library in your classpath. Good Luck.



                       public void runRankReport() {
                            try {
                                Map parameters = new HashMap();
                                parameters.put("Title", "The Rank Report");
                                 
                                JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(getResultList());
                                byte[] bytes = JasperRunManager.runReportToPdf(this.getClass().getResourceAsStream("/rank.jasper"), parameters, ds);
                                HttpServletResponse response = (HttpServletResponse)facesContext.getExternalContext().getResponse();
                                response.setContentType("application/pdf");
                                response.addHeader("Content-Disposition","attachment;filename=RankReport.pdf");
                                response.setContentLength(bytes.length);
                                ServletOutputStream servletOutputStream = response.getOutputStream();
                                servletOutputStream.write(bytes, 0, bytes.length);
                                servletOutputStream.flush();
                                servletOutputStream.close();
                                FacesContext.getCurrentInstance().responseComplete();
                            } catch (JRException jre) {
                                 jre.printStackTrace();

                    Apologies. It was in the ear file, but not in the ear/lib directory. copied it over, and the error is no more!!! thanks again. I seriously think I have classpath issues...I am yet to trouble you again...I am getting another error... :(


                    net.sf.jasperreports.engine.JRException: Class net.sf.jasperreports.engine.xml.JRReportSaxParserFactory should be compatible with net.sf.jasperreports.engine.xml.JRSaxParserFactory

                      Firstly, apologies for the rating. I did not know how to rank it, so I clicked on the first star...It now kept it. In reality,....the ranking is definately 5 stars..


                      Thank-you very much for your code. I really do appreciate it, and I know that it is helping me...


                      Thanks again...

                        I have copied my jasper file in the same location(package) as the java class i am running the code from.
                        I was not sure if it supposed to be in my web project.. ?

                        This is my code:


                        try {
                                       Collection<SurveyEntity> col = surveyManager.getAllSurveys();
                                        JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(col);
                                           byte[] bytes = JasperRunManager.runReportToPdf(this.getClass().getResourceAsStream("/UsersForSurvey.jasper"), parameters, ds);
                                       
                                      HttpServletResponse response = (HttpServletResponse)facesContext.getExternalContext().getResponse();
                                      response.setContentType("application/pdf");
                                      response.addHeader("Content-Disposition","attachment;filename=RankReport.pdf");
                                      response.setContentLength(bytes.length);
                                      ServletOutputStream servletOutputStream = response.getOutputStream();
                                      servletOutputStream.write(bytes, 0, bytes.length);
                                      servletOutputStream.flush();
                                      servletOutputStream.close();
                                      FacesContext.getCurrentInstance().responseComplete();

                        Could you please help me...

                        Thanking you

                          It is clear from the error message that your code cannot find UsersForSurvey.jasper file.


                          How are you packaging your application? Using build file from seam-gen? If you are then look for



                          <target name="jar" depends="compile,copyclasses" 
                                                  description="Build the distribution .jar file">
                                          <copy todir="${jar.dir}">
                                                  <fileset dir="${basedir}/resources">
                                                          <include name="seam.properties" />
                                                          <include name="*.drl" />
                                                  </fileset>




                          Right below that add the following snippet.



                          <fileset dir="${src.action.dir}/com/ericsson/mst/admin/report">
                                                         <include name="*.jasper"/>
                                                    </fileset>



                          Point dir to appropriate location.

                            Hi

                            Thank-you for the reply. I have not tried your solution as yet. But what I was doing since yesterday, was checking the jars included in my classpath...I am not getting a different error from the one above. I think that I may be missing some jars... Please can you advise me as to what jars i should have...

                            The error I am getting now is

                                I tried sending this reply numerous times, but was not sure if you got it. I am using your code to send jasper report to the outputstream. I am getting a whole lot of characters showing up on my web page.


                                Any ideas pleez

                                  I followed the same approach and I get some weird characters on the browserwhen I set the content type as pdf. but for html it works fine. Can some one please give some pointers.


                                  Thanks,

                                    I discovered yesterday evening (after a whole day of checking what was wrong) :(, that when I used a a4j:commandLink to invoke the action, then the funny characters appeared, but when I used h:commandButton it worked fine... 

                                    Hope this helps you
