on bea weblogic ver 6 sp 5(?)

if reguest.getAttribute("something") is null

using

<%= reguest.getAttribute("something") %> prints an empty string

but

<%
if(reguest.getAttribute("something") == null) { // true
...
}
%>

but on weblogic ver 7 sp 4

<%= reguest.getAttribute("something") %> prints a "null"

is this a weblogic bug? why is it in version 6 an emptry string was returned?

protectedVar is inherited by Sub....
and a protected modifier isn't as restrictive as private... so Sub has access to it...
i think the problem i'm encountering is with the stub created by websphere during the deploying of my ear... because in one of the e.printStackTrace() messages.. the exception mention something like ..._DatProration_stub_.... where DatProration is my EJB remote interface.. how can i solve this? i made a simple program that uses the same EJB and invoked the same method and i don't get those RMI exception messages... i need help!!!

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!
