Hi! How do you format the date for a barcode? I'm trying to use date for my barcode. I want it to have the hour, min and sec but when I use the date in the barcode it givec me everything like the MDT FRI and stuffs I dont need. I only need mm/dd/yy, hour, min and sec.

I'm trying to format my date when I use it in barcode. I want to print '101 10/05/2007 1' in barcode. I use this barcode expression ("101 "+$P{inputdate}+" 1"). My problem is how can I format the date when I print the barcode instead of '101 10/05/2007 1' I have '101 Thu May 10 12:37:47 MDT 2007 1'. How can I change the format?

My subreport is working well when I generate the report using iReport. In iReport I use ".\SubReport.jasper" as my subreport expression class. But when I use it in my application it generates an error that it cant find the file ".SubReport.jasper". I'm using absolute path in my application, "C:/Program Files/Apache Software Foundation/Tomcat 5.5/webapps/appsname/WEB-INF/reports/MainReport.jrxml" for the main. I tried using absolute path in iReport using "C:\Program Files\apache Software Foundation\Tomcat 5.5\webapps\appsname\WEB-INF\reports\SubReport.jasper". I does not generate an error but it will not show my subreport. I'm using Spring so I'm guessing since I use absolute path I cant use ".\Subreport.jasper". How come my subreport is not showing in my main report when I use absolute path in iReport? I pointed to that file when I added my subreport on subreport wizard.

I have a report that has a subreport. I'm new to using subreports. How can I fill my subreport then use it in my main report then display the reports as pdf. When I used single report, I just generate a resultset then convert it to JRDataSource then use sendToResponse in my JSF. Do I have to generate JRDataSource first for my subreport? How do I connect the two reports in my application?

Here it is.. public void sendToPDF(byte[] bytes){ HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse(); response.setContentType("application/pdf"); response.addHeader("Content-Disposition","attachment;filename=Report.pdf"); sendToResponse(response, bytes); } private void sendToResponse(HttpServletResponse response, byte[] bytes){ ServletOutputStream servletOutputStream = null; try { servletOutputStream = response.getOutputStream(); response.setContentLength(bytes.length); servletOutputStream.write(bytes, 0, bytes.length); servletOutputStream.flush(); servletOutputStream.close(); } catch (IOException e) { e.printStackTrace(); } FacesContext.getCurrentInstance().responseComplete(); }

Thanks a lot, this works! One more question. Is there a way that I dont have to refresh the page before I can click any buttons or links?

Hi! I have a pdf report that opens when I click a button in my page. But it's not convenient to click back then refresh again if I want to navigate out of the report and continue to navigate throught the page where my button was. Is there a way that I can just open a new browser to display my pdf without navigating away from the page where I click to open the report. Thanks!

Thanks a lot!

Thanks, that helps!

I dont like to have queries in my code but I still want to be able to fill me report using the reports query. Would JREmptyDataSource give empty report. The program right now is using the parameters, my program generates a resultset by executing the queries in my program, then make that into a JRDataSource. After getting the JRDataSource, together with jrxml file, I pass them to a method that generates my byte[].This is the method: public byte[] generatePDFReport(File reportFile, Map parameters, JRDataSource ds) { byte[] bytes = null; try { JasperReport jasperReport = JasperCompileManager.compileReport(reportFile.getPath()); bytes = JasperRunManager.runReportToPdf( jasperReport, parameters, ds); } catch (JRException e) { e.printStackTrace(); } return bytes; } After I get the bytes, I pass it to another method: public void sendToPDFResponse(byte[] bytes){ HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse(); response.setContentType("application/pdf"); sendToResponse(response, bytes); } to publish it in the web. What I want to do now is bypass the method where I get my JRDataSource using my programs query. I want to find a way to just use the query in my xml to get my data and generate byte[]. I saw a method in my JasperManager that have this interface: bytes = JasperRunManager.runReportToPdf( jasperReport, parameters); return bytes; So it uses just the parameters and jasperreport but when I use it it generates just a null byte[].What are the precondition for me to be able to use this method and generate my data? Thanks a lot for helping with this, I'm new to JasperReport but I think it's cool and I want to learn more about it....

How did you generate your byte array? Did you have a query in your application to get the data? That is what I'm doing right now, I create a JRDatasource in my application the fill it report with the data. I'm currently using: bytes = JasperRunManager.runReportToPdf( JasperReport jasperReport, Map parameters, JRDatasource ds ) But I want to get away with queries in my code and just use the queries stored in my reports. I want to do something like this bytes = JasperRunManager.runReportToPdf( JasperReport jasperReport, Map parameters); But for some reason it returns a null value for my bytes. Thanks!

I saw this function in my jasperRunManager.class: public static byte[] runReportToPdf(net.sf.jasperreports.engine.JasperReport jasperReport, java.util.Map map) what are the preconditions for this method to be used?

I'm using JasperReport jasperReport = JasperCompileManager.compileReport(reportFile.getPath()); bytes = JasperRunManager.runReportToPdf( jasperReport, parameters); return bytes; for some reason it returns a null value. What are the conditions so I can use this version of the runReportToPdf. I'm using hibernate and spring Thanks!
