In attempting to bind and test connection to a JRDataProvider class within IReport, I get an error message which reads: "TestProvider" is not a subclass of "net.sf.jasperreports.engine.JRDataSourceProvider" First, the JRDataSourceProvider is an interface. You cannot have a subclass of an interface. More importantly, my TestProvide class implements this interface correctly. I compile it and make it available in IReport classpath. Here's a sample snippet: public class TestDataSourceProvider implements JRDataSourceProvider See doc for more details. THanks, Ken [file name=JRDataSourceProvider_error.doc size=64512]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/JRDataSourceProvider_error.doc[/file]

When testing a custom datasource, I would like to see what code is actually being invoked/ran inside of IReport. I put System.out.println() calls inside my custom datasource, yet I do not see them appear on any panel when I click "Test" datasource. I also hoped I could catch System.out trace on DOS console window running Java version. So I downloaded latest 1.2.5 version. Now it appears I cannot run startup.bat since it appears to hang after reading its own IReport config file. Ack!! Thanks! Ken

Hi, I have a hierarchical collection of data in a custom datasource -- a list of Employees, where for each employee, there is a list of EmployeeTasks. Whereby, when the report runs, I would like to see for each employee, a display of 0-n rows of EmployeeTasks. Question: Am I required to define a subreport within a master in order to display my data? Might I simply define a subdataset? If this is possible, how do I make this work? Thanks, Ken

Hi Why are JasperReports subreports always defined in a separate "xxx.jrxml" file? Why can't the subreport description be embedded in one single xxx.jrxml file? This would reduce programmatic overhead in loading/running a report. Thanks!
