Pass the value as part of the Hashmap into the report template and use the $P parameter to read and display the parameter value from hashmap. HashMap map = new HashMap(); map.put("REPORT_TITLE","xyz"); declare paramter REPORT_TITLE in the template and use $P{REPORT_TITLE} to display the title. Hope this helps, all the best!!!!

Hi, We are having 20 threads to process reports concurrently and in our testing one single report is being invoked by all 20 threads with the same parameter map. We are believing that the error is happening to synchronization issue with scriptlet class. We have defined a custom scriptlet with some methods like numberFormatter, dateFormatter in order to format the data. Can you let us know how scriptlet class is shared across these multiple instance, could this be causing the issue. We are running another test now by remove the script let class from the summary band to see if that resolves the issue, I will let you know the results. I am posting this message to understand the way scriptlet class used when the same report is being run by all threads..... Thanks in advance, Jagadeesh

Hi, Any update on this issue, this issue is holding us from releasing these reports to end users...any help regarding this issue will be greatly appreciated....

Hi, I have attached the java code and the jrxml template producing the problem. We are encountering the java.lang.Integer only during heavy loads where the same report is ran 1000's of times. This error is not reproducible all the time, let me know if you find the root cause for the problem. Jagadeesh [file name=JasperDriver.zip size=15759]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/JasperDriver.zip[/file]

I can get the code, but I need to check with my client before I get it to you. Also I am not able to replicate this issue consistently, it happens very often may 1 out of 100 runs.

we are using JasperReports 1.3.0 in our application and are seeing the exact same error intermittently. The weird part is this error is not reproducable, the same report works fine one time and fails the other time......was there any solution identified for this issue? we tried to run the exact same report 600 times and it executed fine 594 times and thrown the error 6 times. java.lang.ClassCastException: java.lang.Integer at net.sf.jasperreports.engine.fill.JRBaseFiller.resolveBoundElements(JRBaseFiller.java:1088) at net.sf.jasperreports.engine.fill.JRBaseFiller.resolveBoundElements(JRBaseFiller.java:1109) at net.sf.jasperreports.engine.fill.JRBaseFiller.resolveReportBoundElements(JRBaseFiller.java:1126) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillSummary(JRVerticalFiller.java:805) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportEnd(JRVerticalFiller.java:240) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:116) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:751) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:660) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:63) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:402) at com.sam.reports.job.ReportGenerator.executeProcess(ReportGenerator.java:410) Please let us know if there is a solution for this issue

Store the static text in a csv file and provide it as data source for the report....so that template will only have the design and the static data comes from csv file....hope this helps!!!

Can any one help me with this, FileVirtualizer works for me but not SwapFileVitualizer....very urgent, pls help!!!

You can use variables to do this...You must be having 2 fields representing code and amount, I am assuming them as $F{CODE} and $F{AMOUNT} You can define a variables $V{TOTALAMOUNT_KRW},$V{TOTALAMOUNT_USD} etc., with evaluation time as Report and calculation as "Sum" Assign the expression: $F{CODE}.equals("KRW")?$F{AMOUNT}:0 You can replace KRW with different currencies for each variable and use the variables in your report to show the Amounts for each currencies...... All the Best!!! Jagadeesh

Hi, iReports does not contain this property file, iReports uses jasperreports API to fill and export the report. Look for jasperreport jar in the iReports lib directory and this property file will be present in the root folder when you unzip the JAR. All the Best!!!

pdf default font is set to Helvetica in the default.jasper.properties file, change it to the font you want to make it work also you can change other properties like default size etc., net.sf.jasperreports.default.pdf.font.name=Helvetica Hope this helps!!! Jagadeesh

I just tried the exact same report with FileVirtualizer and it ran with out any errors....17095 temp files were created which is equal to the number of pages in the report. I wonder why SwapFileVirtualizer is not working, I would like to get it working as it uses single swap file as opposed to FileVirtualizer....I can get into performance issues with FileVirtualizer due to large number of I/O operations.....please help me in getting SwapFileVirtualizer working.... Thanks and Regards, Jagadeesh

It doesn't contain any images, my report pulls about 30 columns for a specified date range...SQL is returning more than 300K rows....When I try to run the report a swap file is getting created but after the swap file size reaches 200MB its blowing with Out of memory : heap space error message.... Looking at the concept of virtualizer, this should work fine as I am not doing anything fancy.....SQL is embedded with in the template, as jasper does not get data at once this should not create any problems...Is there a minimum requirement of heap space for virtualizer to function properly?? Here is the code I have used for virtualizer: JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign); JRConcurrentSwapFile jrSwapFile = new JRConcurrentSwapFile("C:/Temp",30,4); JRSwapFileVirtualizer virtualizer = new JRSwapFileVirtualizer(4,jrSwapFile,true); data1.put(JRParameter.REPORT_VIRTUALIZER, virtualizer); JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, data1, jdbcConnection); JRVirtualizationContext.getRegistered(jasperPrint).setReadOnly(true); JasperExportManager.exportReportToPdfFile(jasperPrint, "reports/TRExpenseLog.pdf");

Hi, We are trying to produce a report with large data (around million rows) and are getting heap space error while trying to generate the report. I found that virtualizer can solve the issue with space by swapping data with disk space, I have used Swap File Virtualizer and still getting the heap space error. I can see that a swap file of around 200 MB is created on my local and then its erroring out. Here is what I would like to know:: 1. How does Jasper gets the data, does it get all at a time or paginate through the resultset. If it gets the all data at once where does it store? Could this be causing heap space issue, if so how did it created a swap file of around 200MB? Here is the code I have used: JRConcurrentSwapFile jrSwapFile = new JRConcurrentSwapFile("C:/",30,2); JRSwapFileVirtualizer virtualizer = new JRSwapFileVirtualizer(2,jrSwapFile,true); data1.put(JRParameter.REPORT_VIRTUALIZER, virtualizer); JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, data1, jdbcConnection); 2. Can I use JasperServer for running reports, I don't want to use other features like UI, scheduling etc., All I want to do is use JasperServer's JVM to run Reports as there could be memory optimization and virtualization implemented in a betterway. Any pointers to how to solve the issue of genereating large report without heap space error is greatly appreciated. Thanks in advance!!! Jagadeesh
