Eclipse RCP: ClassNotFoundException or How to make loading other packages my class

Details: I am trying to use the Jalapeno framework to connect my RCP application to a Cache database. After establishing the connection, I try to get all the data from the table in the same way as in the Jalapeno manual:

if (objManager==null) return;
DBClass cortege = null;
try {
Iterator terms = objManager.openByQuery(DBClass.class, null, null);
System.out.println("terms ok");
while (terms.hasNext()){
    System.out.println("has next");
    cortege = (DBClass)terms.next();
}

this code compiles, runs and throws an exception

java.lang.RuntimeException: myPluginId.views.DBClass
at com.intersys.objects.POJOIterator.next(POJOIterator.java:75)
   ...skip...
   Caused by: java.lang.ClassNotFoundException: myPlugin.views.DBClass

in terms.next (); I can't get it at all ... an instance of the DBClass class has just been created, but the class cannot be loaded. , then I tried to put this code in a simple java application (and not eclipse rcp), and everything went fine. , so I think that part of loading the Eclipse lock class.

I also tried loading the class before calling terms.next ();

Bundle b = Platform.getBundle("myPluginId");
try {
b.loadClass("DBClass");
} catch (ClassNotFoundException e) {
System.out.println("no class");
e.printStackTrace();
}
