Why do I get the following exception when viewing the JNDI tree?

isSerializable(class.javax.naming.Binding)

java.io.NotSerializableException:

java.io.PrintWriter at

java.io.ObjectOutputStream.OutputObject

The Weblogic Server JNDI implementation requires objects to be serializable, not referencable. A PrintWriter cannot be serialized and therefore should be declared transient.
