Hi ,
I am invoking a method getDetails(param1, param2) of
stateless session bean from a servlet. The method is
returning java.util.Vector. I am adding objects in
this vector all of which are instances of class CL
whose definition is
public Class CL {
private variable x;
private variable y;
public setter method for x;
public setter method for y;
public getter method for x;
public getter method for y;
}
I have written the following code to populate the
vector in EJB ,
Vector vec = new Vector();
CL cl1 = new CL();
cl1.setterforX(val1);
cl1.setterforY(val2);
vec.addElement((Objct)cl1);
Similary I am adding few other objects(cl2, cl2 etc)
in the vector vec. The EJB method is then returning
this vector to the client(which is a servlet). When I
invoke the method getDetails(param1, param2) from
servlet { as Vector result =
remote_object.getDetails(param1, param2) }, I get this
error on the browser :
"
java.rmi.ServerException: RemoteException occurred in
server thread; nested exception is:
java.rmi.MarshalException: Exception occurred in
server thread; nested exception is:
java.io.NotSerializableException
"
My Servlet and EJB are running on the same machine and
my server platform is WebSphere Application Server
3.5 . When I tested the program in VisualAge for Java
3.5 's EJB test environment, I get
java.lang.ClassCastException { when I invoked method
getDetails(param1, param2) }.
Any help will be much appreciated.
