i'm trying to invoke an EJB method that returns a Utility class that implements a serializable interface... but websphere application server keeps throwing a MarshalException exception... here's upper part of the exception message..
java.rmi.MarshalException: CORBA BAD_PARAM 6 Maybe; nested exception is: java.io.NotSerializableException
at com.ibm.rmi.javax.rmi.CORBA.Util.mapSystemException(util.java:144)
at javax.rmi.CORBA.Util.mapSystemException(Util.java:51).... blah.. blah
weird thing is... my application used to work before... and as far as i'm concerned, nobody changed the configuration of the server... even my old EAR files now doesn't work and i get the same error message...
help!
