I simply need my beans to be added to my standalone jasperstudio 5.5.0 class is like this public class JFactory { public static java.util.Collection getList() { java.util.Collection AllBeans = new ArrayList(); MyBean bean = new MyBean(); some adds... and thenreturn the collection AllBeans which is an arraylist.... Then I create the new data adapter (Javabean collection) enter the class (whit and w/out package) method getList and select the JAR which is in the same path oh the .JRXML e .jasper I'm frustrated about it. please help me! best regards to you allMarcus
