Anyone.... please help!!!

Hi all, I have multiple subreports defined and everything is working great except that the report always prints out an extra report with null value. Does anyone know why? Thanks, Bob

Hi Can I pass a collection of custom datasource as list to report and subreports? I tried this but then I got the following error: Caused by: net.sf.jasperreports.engine.JRException: Incompatible net.sf.jasperreports.engine.data.JRBeanCollectionDataSource value assigned to parameter REPORT_DATA_SOURCE in the masterReport dataset.

Well, I bundled the classes into a jar file and included it in the classpath and it works fine. Couldn't include individual class though... weird, don't know why...

Can somebody help...!!!! I included the abc.myservice.ClassBService class in the classpath and when I compile the template I get java.util.zip.ZipException: error in opening zip file...

Thanks for your response... When I included the abc.myservice.ClassBService class in the classpath. I get java.util.zip.ZipException: error in opening zip file... Weird...Dod you have any ideas? Thanks-

Hi all, I tried including the package but still get an error: java.lang.ClassNotFoundException: abc.myservice.ClassBService Any idea? Thanks-

Hi, Can someone help show me how to pass diff datasource to subreport. I am having a problem where I want to pass an array of DataSource to master report. How can I pass datsource one by one from master report to the subreport. i.e: subds[0], subds[1]...subds[n]... Thanks--- Here is what I have in the controller code: ============================ HibernateQueryResultDataSource ds = (master datasource) HibernateQueryResultDataSource subds = new HibernateQueryResultDataSource[input.size()]; for (int i=0; i < input.size(); i++){ List<?> reportQuery = getReport(input.get(i)); String[] fields = new String[] {"a", "b", "c"}; subds = new HibernateQueryResultDataSource(reportQuery, fields); } model.put("dataSource", ds); model.put("subDataSource", subds); return model;

Hi, I am having a similar problem where I pass an array of DataSource to master report. How can I pas datsource one by one from master report to the subreport. i.e: subds[0], subds[1]...subds[n]... Thanks--- Here is what I have in the controller code: ============================ HibernateQueryResultDataSource ds = (master datasource) HibernateQueryResultDataSource subds = new HibernateQueryResultDataSource[input.size()]; for (int i=0; i < input.size(); i++){ List<?> reportQuery = getReport(input.get(i)); String[] fields = new String[] {"a", "b", "c"}; subds = new HibernateQueryResultDataSource(reportQuery, fields); } model.put("dataSource", ds); model.put("subDataSource", subds); return model;

Hi All, Well, I think I can create a subreport to handle this issue, but is there a way to call and pass it diff datasources? Thanks-

Hi, Can somebody help... How can I append one report after another in Spring Hibernate framework?

Hi, I am using Spring+Hibernate, how can I appending one report after another in Spring+Hibernate framework? Thanks, Bob

Hi shrije, Thanks for your reply, I am using Jasper with Spring framework and the Jasper template is the same for all reports... Can code similar to this happen inside the template or a scriptless? Bob

Hi All, I am trying to create a template for a report that can be from 1 to many (around 10 reports) in one report output. Depending on the user input (~10 drop down lists and each list if selected will eventually populate a report). Ex. if user select inputs from 5 drop down lists then I will have to generate 5 reports, one after another, if they select 10 then create 10... What is a best way to accomplishing this? Thanks- Bob

Lucian, I found a work around for this issue by adding a check for the returned column in question and convert it to Integer... i.e: ==== public Object getFieldValue(JRField field) throws JRException{ Object value = null; int index = getFieldIndex(field.getName()); if (index !=-1){ //This block is added... Object[] values = (Object[])currentValue; if("columnInQuestion".equalsIgnoreCase(field.getName())) { Integer myInt = new Integer(values[index].toString()); value = myInt; }else{ value = values[index]; } } return value; }
