jasper-reports

问题 I have multiple Jasper Reports (with sub-reports) throughout my application. For some reason, one report (that also contains sub-reports) isn't working anymore. After debugging more than 1 day, I found out that it enters an infinite loop and keeps creating Threads for sub-report filling. Debugger keeps looping between: JRSubReportRunnable.java public void run() { running = true; error = null; try { fillSubreport.fillSubreport(); } catch (JRFillInterruptedException e) { //If the subreport

问题 This is my current jrxml file: <?xml version="1.0" encoding="UTF-8"?> <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="report1" language="groovy" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="18199607-277f

问题 While I am running the following query in jasper reports, I got the exception. "net.sf.jasperreports.engine.JRException: Error executing SQL statement for : Activity_Summary". Activity_Summery_Report is my jrxml file name. The query is declare @startdate as datetime; declare @enddate as datetime; declare @sitegroup as nvarchar(50); set @startdate = DATEADD(hh, +0, $P{StartDate}); set @enddate = DATEADD(hh, +0, $P{EndDate}); set @sitegroup = 'BBXNCR'; set NOCOUNT ON; -- Added by JC230090:

问题 A PDF generated in iReport using the 'Times New Roman' font appears to be using 'Arial' for its print version. Any idea what the problem is? 回答1: I've found that, at least for me, I must explicitly set the pdfEncoding attribute, as well as pdfFontName and isPdfEmbedded, on each font tag in the xml, even when using the system encoding, and that "Identity-H" seems to be needed when using unicode. So: Make sure your ttf font files are available on the classpath <font ... pdfFontName="filename

问题 How can I avoid the column name repeating in JRXML? Is there any attribute for avoiding having the column header in each page when generating a report using JRXML and Jasper? 回答1: If the header will always be on a specific page (e.g. the first page), you can add <printWhenExpression><![CDATA[$V{PAGE_NUMBER}==1]]></printWhenExpression> to the band, which will make it only print on page 1. PAGE_NUMBER is an inbuilt variable that is automatically incremented as the report is generated. 回答2: Set

问题 In a jasper report, with iReports Designer one can set the Report Name to some value (in iReports, this is on the most top node in the report inspector). How can the value of this parameter been accessed later within e.g. a variable or a textfield of the same report? 回答1: With help of JASPER_REPORT parameter we can get instance of JasperReport class. This is the current template object. With help of JasperReport.getName() method we can get the report name. Example of template <?xml version="1

问题 I have some issue here, I searched it and got that iReport Designer cannot working with JDK 8. but I need to using method on my project that using JDK 8. if I use my method it will give a warning. Unsupported major.minor version 52.0 is there any solution for it? so I can run my method? 回答1: As Alex already said, iReport Designer is deprecated and will not be supported any further. Since version 5.5 Jaspersoft Studio is the official and supported Client for Jaspersoft. In Jaspersoft Studio

问题 I have designed an iReport where it should display all the records in the report. If a report has 2 pages for example then first page should display "To be continued" second page should display "End of the report" irrespective of number of pages you are working with. I have placed a label at the footer of the report and changed the properties "print when expression" as $V{PAGE_NUMBER}.equals($V{PAGE_COUNT}.toString()) ? "End of Report" : "Continue" and displays error while executing the
