hello I have just installed on my computer another eclipse 3.2 with plugin Ireport and it works fine! In the same computer, i then retry to run Ireport from RSA (IBM solution over eclipse3.2) , and this time it works too!! without changing anything to the plugin Ireport. As if the fact i succeded to run Ireport from eclipse 3.2 a first time allowed RSA and plugin Ireport to work fine. If someone has an explanation ... But i do not know why I still can not install the plugin under eclipse 3.2 in the other computer : the message "Resulting configuration does not contain the platform" still appears... and reading other forums i am not the only one to have this message when installing an eclipse plugin regards Françoise

hello sorry to insist, but i really need help to find why i can not use the plugin eclipse ireport in my computers! I retried to install the plugin under IBM Rational Software Architect (RSA) after having changed the place where ireport 1.3.0 was installed. In the .ireport directory, i have the file ireport1.3.0.location up to date. Ireport begins to run but then the message "ireport is taking to much time to start ... retry later" anyone regards Françoise

Hello Nobody has an idea to solve this problem? I add that in the 2 usecases the computer is with Windows 2000. regards Françoise

Hello I have just installed Ireport eclipse plugin under RSA (IBM software based on eclipse3.2). The installation is OK. I try to launch inside RSA ireport 1.3.0 but it does not start : the image of ireports (two nice deers!)is shown with the message "setting locale ..." in English. The java process is still running and i have to kill it manually. If I run Ireport 1.3.0 outside RSA, it runs well. I have installed the plugin as explained in the html demonstration provided with ireport1.3.0. To verify if it was due to RSA, in another computer (windows 2000), i have tried to install the plugin in eclipse 3.2 , and the installation can not be done : there is the error message "resilting configuration does not contain the platform " as you can see in the file attached regards Françoise [file name=installPluginIreportEclipse.doc size=42496]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/installPluginIreportEclipse.doc[/file] Post edited by: frblusso, at: 2007/03/19 14:39

hello Strangely, I made new load test(pdf and rtf format), and all was ok. But I notice some differences between jr1.20 et jr1.3.0 about the virtualizer. When I've made load test with jr1.2.0, the cpu consumption was better with virtualizer than without it, but the response time was longer. With jr1.3.0, the consumption of cpu is still better using virtualizer, but the response time is also better! i made test about reports with 70 and 350 pages, simulating 10,50 and 100 simultaneous users making the same request. Could you confirm me that Virtualizer has been improved on those 2 points :cpu consumtion and response time? another question : what happens if we use virtualizer and the reports is in fact shorter than the parameter of the firualizer (exemeple, a report of 50 pages with a parameter to 60). regards Françoise

Hello I make some load tests on jasperreport 1.3.0 using the virtualizer in a web application (Websphere) when we run more than 20 users in parallel making the same request : generating a pdf report with the virtualizer, we see on was logs that many threads are created, and then a timeout error and problems of datasource connections occurs. we run on a websphere server 5.1. Did you already hear about problems using virtualizer ? regards Françoise

the jexcelapi exporter seems to write some png file under /var/tmp file system that was full on my case. could ou confirm me that? Is it possible to generate temporary files under another file system? regards françoise

there is no problem with exporting the same report to df or rtf format. and strangely it works fine in our development unix platform but not in our test unix platform. I just discovered that another exception was logged : javax.imageio.IIOException: I/O error writing PNG file! at net.sf.jasperreports.engine.util.JRJdk14ImageEncoder.encode(JRJdk14ImageEncoder.java:90) at net.sf.jasperreports.engine.util.JRAbstractImageEncoder.encode(JRAbstractImageEncoder.java:74) at net.sf.jasperreports.engine.util.JRImageLoader.loadImageDataFromAWTImage(JRImageLoader.java:166) at net.sf.jasperreports.engine.export.JExcelApiExporter.exportImage(JExcelApiExporter.java:738) and then a java.io.IOException: No space left on device . i have to contact our system engineers to enlarge out file system but, i ' d like to know what is done with an image file (.jpg) . Does jexcelapi transform it to a png file that must be written on the file system? regards françoise

hello i 'd like to read the solution to this problem but the link can not be read because of a restrict access. could someone give me the solution in this forum, please regards Françoise

I found this solution to my problem : i have a bean Avion (id, name, java.util.List flightlist) in the main report, I insert a subreport, with this property, use datasource expression new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{flightlist}) In Subreport(other) i put the path to the subreport. and in my java application, i have just to create the JRDatasource to give me the data Avion. regards Françoise

Hello i have the problem below : i have a list of Planes. A plane contains text fields (id, name) and a list of flights(object B) Each flight has text fields f1, f2 ...; . I want to create a report to list all the Planes id ,names and flights details For example : plane1 A320 volAF volKLM volXXX plane2 A330 volAF volXXX i have created in my java programm a JRBeanCollectionDataSource(PlanesList) that have all the information it contains a list of (id, name ,flightList) but how could i put flightList detail information in the report? I think I have to use a subreport , the main report is used to generate the list of planes whith text fields id and name. In the subreport I list the text attibutes of one flight. The problem is that I do not know how to specify that the subreport needs to read (as its own datasource) the list flightList found in the main report. i search in the forum for any information but i only found a solution if the first list has only one object. i really need help, thancks! Regards

i have the same problem and i do not find any solutions regards Françoise

hello i tried to apply this solution but when i compile the main report i have this error net.sf.jasperreports.engine.JRException:ÂErrorsÂwereÂencounteredÂwhenÂcompilingÂreportÂexpressionsÂclassÂfile: 1.ÂJavaBeanDataSourceÂcannotÂbeÂresolvedÂtoÂaÂtype  valueÂ=Â(net.sf.jasperreports.engine.JRDataSource)(((JavaBeanDataSource)((net.sf.jasperreports.engine.JRDataSource)parameter_REPORT_DATA_SOURCE.getValue())).vols()); i have set ((JavaBeanDataSource)$P{REPORT_DATA_SOURCE}).vols() in the connection/datasource expression my javabean datasource contains some fields, vols is one of those fields. i use ireport1.2.0. thanks for any help Françoise

so what is the solution? may i have to migrate to the latest version of ireport to have the correct interface of connection properties? Françoise

in fact , i haven't the choice in ireport 1.2.0 : when i define the datasource, i have to write the path in the field select expression : so i define one datasource for the main report and one for the subreport, each one with a different expression. regards, Françoise

hello i have succeded to generate a pdf, with the jasperreports1.2.0/demo/samples/xmldatsource inside my web application. the problem is that i do not succeed to preview the result with ireport1.2.0. I have this message when i run a preview from the main report : WARNÂÂJRXPathQueryExecuterÂÂ(<init>,Â68ÂÂ)Â-ÂTheÂsuppliedÂorg.w3c.dom.DocumentÂobjectÂisÂnull. and the pdf genrated shows only the data from the main datasource (/Northwind/Customers) and nothings for the second one (xpath =/Northwind/Orders[CustomerID=$P{CustomerID}]). In the java code i had to set the XML_DATA_DOCUMENT to pass the data to the subreport, but how can i do it inside ireport? i have another question, when i search inside the Ireport forum, i obtain response from all forums (jasper report, archives,...) is it possible to restrict to the current forum which i use? or at least , sort the list by forum? regards Françoise
