sry, not sure what to insert for username and password...where can I register? regards daniel

hey all, well, I finally solved the problem ! there was some kind of problem in my .jrmxl-file. I think it had sth. to do with my group-settings...because after I deleted all groups and constructed them all new from the beginning, everything works fine ;) what seems strange, that I got no problems converting the report in iReport, these group settings only cause problems in the jasperserver environment ... anyway, big thanks for your help khahn. regards

same here, any ideas? EDIT: seems to occur, when I run a report before webpage finished loading... Post Edited by joka83 at 05/12/2011 11:22

Hey again, I ran the "AllAccounts"-report and exported it to pdf and xslt later. My pdf file got 43 pages and my xslt-export 1310 lines of information. All fields and information are shown ! Sometimes when I try to run an export I get an error like: Oh my!The server has encountered an error. Please excuse the inconvenience. Error Messageorg.springframework.webflow.execution.repository.snapshot.SnapshotNotFoundException: No flow execution snapshot could be found with id '1'; perhaps the snapshot has been removed? Error Traceorg.springframework.webflow.execution.repository.snapshot.SnapshotNotFoundException: No flow execution snapshot could be found with id '1'; perhaps the snapshot has been removed? at org.springframework.webflow.execution.repository.impl.SimpleFlowExecutionSnapshotGroup.getSnapshot(SimpleFlowExecutionSnapshotGroup.java:74) ...... So it seems sth. is wrong with the springframework ?! When I restart my server it works again. EDIT: seems to occur, when I run a report before webpage finished loading... I attached 2 files for you. File 1 shows a screen I see when i run my report out of the repository, picture 2 shows a screen, I get after exporting to pdf. As you can see, some fields like "Jahr" or "Monat" aren't displayed after I ran the report, they are only visible in some certain formats like pdf or flash after an export... Hope it helps you a bit :( Thanks for your help ! regards daniel Post Edited by joka83 at 05/12/2011 11:21

Hey khahn, thanks for your answer again ;) well, i never heard of Ad Hoc Designer before, because I only use the free community-editions of jaspersoft, in this case JasperReports Server. With preview I meant the view you get, when you run a report out of your server - repository, before you decide to export it to different formats... Hard to describe, hope you got me?! ;)) regards daniel

Hey khahn, thanks for your help ! well, I don't know if the server is set to display Full oder Sample data, can you give me a hint where to find, or where to change this information? I don't think that my system is too slow, cause generating the report only takes about 1-2 seconds, so maybe there is an issue with "display full data" like u mentioned ? looking forward to your next message ;) regards daniel

hey, I got some strange issues exporting reports to some specific formats. In the report preview of JasperServer some report fields aren't filled with data, but when i export the report to .pdf all fields/data are perfectly shown. When I right-click-save the pdf-export and try to open it later on my desktop i get an error like "Acrobat Reader can't open dummy.pdf cause datatype isn't supported or file is damaged". I use the latest Acrobat Reader version. Which version do I have to use in order to view the pdf-files later? If i use the scheduler of jasperserver, I am able to run the pdf !!! When I export the report to .csv-, or flash-format all fields are printed, but when I use xls-format some fields are missing, any ideas what the problem could be ? help would be really great ;) regards daniel Post Edited by joka83 at 05/08/2011 13:53

Hey guys, I am trying to establish a custom bean dataSet in JasperServer. I wrote following classes: public class DataSourceFactory { public ReportDataSourceService createDB(){ return new DataSourceService(); } } public class DataSourceService implements ReportDataSourceService { public void closeConnection() { //TODO: add connection close support. } public void setReportParameterValues(Map parameters) { parameters.put(JRParameter.REPORT_DATA_SOURCE, Transform.readXML()); } } public class Transform implements JRDataSource{ public static JRDataSource readXML() { **stuff to get the data and put it into a JRDataSource container** JRDataSource ds = new JRBeanCollectionDataSource(items); return ds; } public Object getFieldValue(JRField field) throws JRException {... public boolean next() throws JRException {... what I got: I established the bean via springbeans and I am able to run the report ! My problem is, that only 1 field is printed, the other 2 fields dont get filled. As far as I try to use the classes in iReport, everythings works fine, and the report get 100% filled with the right data. But whenever I use them at the JasperServer, only 1 field is printed in the resulting report :( I have no idea where the problem is and what to do ... I think the main problem is, that the 2 implemented methods of my transform class (next, getFieldValue) are never accessed.. so I think there might be my fault. might there be a problem with "JRDataSource ds = new JRBeanCollectionDataSource(items);"? each of my items-dataset consists of ("name","year","month")... Any help or push into the right direction would be great ... if you need additional informations to help me, feel free to ask ;) regards Post Edited by joka83 at 05/03/2011 13:42

hey guys, me again ;) i just wrote a factory class which returns a reportdatasourceservice....works fine, but now i get an error called "Incompatible java.util.ArrayList value assigned to parameter REPORT_DATA_SOURCE in the report1 dataset." I dont find any help, which values i could use there? any help? whats my fault? some tipps would be great ;) regards daniel update: I am able to do the report, but no pages are shown...think there is a problem submitting the arraylist to the report generator?! :( Post Edited by joka83 at 05/01/2011 09:25

hey tkavanagh, thanks a lot, I finally got my bean datasource working in ireports ;) but when I try to connect it to your jasperserver product i face new problems... i published my datasource via spring beans and I am able to get a "Connection passed"-Success whenever I try to connect to my database ! (Bean Data Source) ;))) bean name is the id I used in spring bean application context and the bean method is the method which returns an arraylist of beans. but when I try to fill my custom Report with the datasource I get an issue called: java.lang.ClassCastException: java.util.ArrayList cannot be cast to com.jaspersoft.jasperserver.api.metadata.jasperreports.service.ReportDataSourceService Error Tracejava.lang.ClassCastException: java.util.ArrayList cannot be cast to com.jaspersoft.jasperserver.api.metadata.jasperreports.service.ReportDataSourceService at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.BeanReportDataSourceServiceFactory.createService(BeanReportDataSourceServiceFactory.java:86) at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl.createDataSourceService(EngineServiceImpl.java:799) at ... In my application I return an ArrayList of Beans. Well in iReport it works great, but why doesnt it in JasperServer... what do i have to do? any help would be nice...its a great feeling to see things working fine ;) Post Edited by joka83 at 04/29/2011 13:30

hey everybody, I got a few problems in understanding the application-context file for the javabeans datasource example :( <bean id="myCustomDataSource" class="com.jaspersoft.jasperserver.api.engine.jasperreports.util.CustomDataSourceDefinition"> <property name="factory" ref="customDataSourceServiceFactory"/> <property name="name" value="myCustomDataSource"/> <property name="serviceClassName" value="example.cds.CustomSimplifiedDataSourceService"/> I dont understand all of these elements... What I understand is, that <property name="serviceClassName" value="example.cds.CustomSimplifiedDataSourceService"/> should point to the javaclass, which implements ReportDataSourceService . but I dont understand the firs 3 lines: I assume, that "bean id" just needs to be a unique key to identify the bean, but which class do I need to call there? And what about line 2 and 3? I neither find files nor methods named "customDataSourceServiceFactory" or "myCustomDataSource" in the whole sample project :( I think I just need a push into the right direction ... plz help me out :( regards

Well, after nearly 9hours trying to establish a custom java bean datasource on the server, I am that close to become crazy. Is there any good tutorial out there, which gives a step by step view on this topic? especially on creating the application-context file? the docs delivered within the software are a joke in my opinion !! regards daniel Post Edited by joka83 at 04/15/2011 17:11

update again: if I comment the part in which I connect to the DM server out, and add a dummy value to my collection, the iReport datasource connection test is successfull !!! so to sum up, there must be a problem telling iReport how to connect to the DM server...any helpfull ideas?

update: I implemented a method called "public static ArrayList<DataBean> getBeanCollection()" which returns an arraylist of beans, in iReport I created a new datsource (javabeans set datasource), with my given factory class and the methode to retrive the array or the collection of beans...(getBeanCollection)... whenever I hit "Test" i get the errormsg : "Exception General problem: null"... any ideas? i put my whole project in a jar file and published it to iReport classpath as well as all the jars needed to connect to the document management server...
