Examples of javax.naming.CannotProceedException

javax.naming.CannotProceedException
This exception is thrown to indicate that the operation reached a point in the name where the operation cannot proceed any further. When performing an operation on a composite name, a naming service provider may reach a part of the name that does not belong to its namespace. At that point, it can construct a CannotProceedException and then invoke methods provided by javax.naming.spi.NamingManager (such as getContinuationContext()) to locate another provider to continue the operation. If this is not possible, this exception is raised to the caller of the context operation.
If the program wants to handle this exception in particular, it should catch CannotProceedException explicitly before attempting to catch NamingException.
A CannotProceedException instance is not synchronized against concurrent multithreaded access. Multiple threads trying to access and modify CannotProceedException should lock the object. @author Rosanna Lee @author Scott Seligman @since 1.3
