But the stacktrace says
java.io.NotSerializableException:
org.apache.coyote.tomcat5.CoyoteRequestFacade
at
java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054)
at
java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:13
32)
at
Since CoyoteRequestFacade is a tomcat class, I assume it has to be fixed
by the tomcat team. Unless the actual object that is not Serializable
not CoyoteRequestFacade is available somewhere else...
