[jboss-user] [EJB/JBoss] - CMP finder method: java.lang.ClassNotFoundException: org.jbo

Hello! i have a exception using my finder-methods. The application deploys just fine, i can access my session bean, create and remove entities, findByPrimaryKey(), i can even use one of my finder-methods (that returns just one entity): @ejb.finder query="SELECT OBJECT(e) FROM Entidad as e where e.name = ?1" signature="ej7.interfaces.EntidadData findCompanyName(String name)" but when i invoke this other one (it returns a Collection): @ejb.finder query="SELECT OBJECT(e) FROM Entidad e" signature="java.util.Collection findCompanyByEmployees(int number)" Jboss throws the following error: java.lang.reflect.UndeclaredThrowableException at $Proxy1.findCompanyByEmployees(Unknown Source) at ej7.test.TestBean.testGetCompanyEmployees(TestBean.java:145) at ej7.test.Cliente.Test(Cliente.java:23) at ej7.test.Cliente.main(Cliente.java:44) Caused by: java.lang.ClassNotFoundException: org.jboss.ejb.plugins.local.EntityProxy (no security manager: RMI class loader disabled) at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:371) at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:165) at java.rmi.server.RMIClassLoader$2.loadClass(RMIClassLoader.java:620) at java.rmi.server.RMIClassLoader.loadClass(RMIClassLoader.java:247) I read in other post that my error could be that I am trying to return a local interface over RMI. But in this case, both finder methods would fail, not only the second one! Any idea will be very helpful, Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3992872#...
