We are having java.lang.InterruptedException from net.sf.jasperreports.engine.fill.JRThreadSubreportRunner in our logs while using the jasperreports, though the pdfs are getting generated fine. Wanted to know if we should be concerned about it if we were to leave it this way and if there are any resolutions. One example extracted from log file: 2008-04-22 08:24:33,755 ubreport filler orts.engine.fill.JRThreadSubreportRunner ERROR Fill 380559: exception java.lang.InterruptedException at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:429) at net.sf.jasperreports.engine.fill.JRThreadSubreportRunner.suspend(JRThreadSubreportRunner.java:189) at net.sf.jasperreports.engine.fill.JRBaseFiller.suspendSubreportRunner(JRBaseFiller.java:1683) at net.sf.jasperreports.engine.fill.JRVerticalFiller.addPage(JRVerticalFiller.java:1185) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillPageHeader(JRVerticalFiller.java:376) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:226) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:113) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:763) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:688) at net.sf.jasperreports.engine.fill.JRFillSubreport.fillSubreport(JRFillSubreport.java:526) at net.sf.jasperreports.engine.fill.JRSubreportRunnable.run(JRSubreportRunnable.java:63) at net.sf.jasperreports.engine.fill.JRThreadSubreportRunner.run(JRThreadSubreportRunner.java:209) at java.lang.Thread.run(Thread.java:534)

actually jus curious to know if this is a limitation of jasper report or bug?

Is there any limit to the no. of subreports that we can include in a main report without hitting pages of data with an additional blank page? This is bcos I hv just discovered that a blank page will be generated if we hv more than 58 subreports. ===Main Rpt1=== subreport1 subreport2 ... subreport59 subreport60 ... subreport100 footer =============== Above Main Rpt1 produces Page1 of data, Page2 of data, Page3 of blank space(strange) whereas it will be different & ok for below scenario: ===Main Rpt2=== subreport1 subreport2 ... subreport58 footer =============== Main Rpt2 produces only Page1 of data, Page2 of data ONLY without extra blank page.

Hi, Can subreports be generated dynamically on the fly during runtime? If yes, can give suggestions on how this can be done? Requirements: - Each subreport will use a different xml datasource. - The number of subreports to be generated depends on user's selection. Thanks & Regards.

Hi, is it possible to have main report & subreport using different xml datasources? for example: main report to use "a.xml" subreport to use "b.xml" Due to my project requirements, I can't combine the 2 xmls contents. If it can be done, p/s help provide an example of datasource expression when including the subreport. Thank U!

thanks 4 e tip on e common template, will adopt tat for header & footer :) but i still need help for the maintenance of the common Style used by multiple reports. would prfer to update only at one place, rather than opening multiple jrxmls to change common style properties. any comments abt wat i hv done earlier, did i follow e sample app steps correctly?

But I realise that after I opened one of the jrxmls to edit in IReport & saved & then reopened in text editor, the "&reportStyles;" is gone & replaced by the content inside ReportStyles.ent i.e. all the styles are being listed out in the jrxml. This leads back to the same initial problem. Can anyone p/s suggest a better alternative way to include style so that next time, I only need to modify at a single place?

I got it after viewing demosamplesquery. In textual summary, it's as follows: 1) In the jrxmls, declare the style representation as "&reportStyles;" 2)at the top of every jrxml, specify: <!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd" [ <!ENTITY reportStyles SYSTEM "./ReportStyles.ent"> ]> 3)Create a file named ReportStyles.ent with the style specification e.g. <style name="Arial_Normal" backcolor="#00CCCC" isDefault="true" fontName="Arial" fontSize="12" pdfFontName="Helvetica" pdfEncoding="Cp1252" isPdfEmbedded="false"/> <style name="Arial_Bold" isDefault="false" fontName="Arial" fontSize="12" isBold="true" pdfFontName="Helvetica-Bold" pdfEncoding="Cp1252" isPdfEmbedded="false"/> <style name="Arial_Italic" isDefault="false" fontName="Arial" fontSize="12" isItalic="true" pdfFontName="Helvetica-Oblique" pdfEncoding="Cp1252" isPdfEmbedded="false"/>

Is it possible to use include files and styles with JasperReports so that colors and styles can be changed in a single place across all reports instead of being copied all over the place? something similar to cascading css used in HTML? If yes, can describe how it can be done? thanks.

I have solved the problem by replacing: wrong one: "((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/person/email")" as connection expression (of type datasource expression) with correct one: "((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{subreport_project_ds}).subDataSource("/person/email")"

I'm using iReport 1.2.8 for this scenario. === Attached are 3 files used: 1) addrBook.jrxml (main report) 2) addrBookEmail.jrxml (subreport) 3) addy.xml === Connections properties are as follows: Name: addressBookDS Type of connection / datasource: XML file datasource XML file: [somepath]addy.xml Create datasource using this expression: /addressbook/category/person === I have a main report with the following fields: FIELD NAME DESCRIPTION TYPE ID @id Integer LASTNAME lastname String FIRSTNAME forname String CATEGORY ancestor::category/@name String === I have one subreport email addresses. This subreport element has "((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/person/email")" as connection expression (of type datasource expression) and as subreport expression "/addrBookEmail.jasper" of type String. === In addrBookEmail.jasper I have defined only one field: Field Name Field Description Type EMAIL .(i.e. a dot here) java.lang.String === I encountered the following compilation errors when I try to compile the main report: ErrorÂfillingÂprint...

Apparently it works in both version now that I had corrected the image path from ""..\..\images\reports\"" to "images\reports\" Does tat suggest tat version 1.2.1 is more lenient, less strict in handling classpath etc.?

Hi, P/s advise. I encountered the following runtime exception after I migrate from Ireport 1.2.1 to 1.2.5: net.sf.jasperreports.engine.JRException:ÂImageÂnotÂfound It still works on my verson 1.2.1 copy. Regards, Felicia

Hi, Would like to ask abt the following: 1) How easy is it to do so? 2) What are the steps involved? 3) Is version 1.2.5 stable? Or it advisable to migrate to 1.2.4 instead? Regards.
