Hi there I installed Studio Jaspersoft 1.0.1 for Eclipse Elios, then created a java project and from the perspective Report Design I created a report NEW_REPORT.jrxml. I downloaded com-jaspersoft-ireport.jar and placed in a lib folder of my eclipse project, so I added to buidlpath. com-jaspersoft-ireport.jar contains com.jaspersoft.ireport.examples.beans.PersonBean.class and com.jaspersoft.ireport.examples.PersonBeansDataSource.class. I created a data adapter with the name 'New Data Adatper' of type 'class DataSourceProvider JasperReports'. I accepted the proposal com.jaspersoft.studio.data.sample.PersonBeansDataSource, and the test was successful. For NEW_REPORT.jrxml I tried to use the fields outline->fileds-> right click -> Datset & Query.... Select data source 'New Data Adatper', and JavaBeans tab className: com.jaspersoft.ireport.examples.beans.PersonBean but I get a message 'Class not found com.jaspersoft.ireport.examples.beans.PersonBean' What did I do wrong?
