Hello. I'm not sure this is a orion specific issue. Is it true, that serializing a java.lang.Class object and recreating it in a different VM can cause problems? If have a bean which takes a Class[] as arguement. Class implements Serializable, thats not the problem, but when I call the bean, the EJBcode at serverside always receives a NULL-pointer, even when I put something different as an argument. I think that because Class is defined not only by name, but also by it's ClassLoader, it could cause problems when deserializing it? what do you think? How do you transport Class-Object over RMI?
