To associate attributes with the new binding, you use DirContext. To overwrite an existing binding, use Context. You can then read the object back using Context. Running this example produces the following output. Note: The procedures described here are for binding a serializable object in a directory service that follows the schema defined in RFC These procedures might not be generally applicable to other naming and directory services that support binding a serializable object with a specified codebase.
When a serialized object is bound in the directory as shown in the previous example, applications that read the serialized object from the directory must have access to the class definitions necessary to deserialize the object. Alternatively, you can record a codebase with the serialized object in the directory, either when you bind the object or subsequently by adding an attribute by using DirContext.
You can use any attribute to record this codebase and have your application read that attribute from the directory and use it appropriately. Or you can use the "javaCodebase" attribute specified in. In the latter case, Oracle's LDAP service provider will automatically use the attribute to load the class definitions as needed. The following example resembles the one for binding a java. It differs in that it uses a user-defined Serializable class, Flower , and supplies a "javaCodebase" attribute that contains the location of Flower 's class definition.
I didn't have to read the files and populate the arrays again and again. In essense :. Serialization is the process of converting a set of object instances that contain references to each other into a linear stream of bytes, which can then be sent through a socket, stored to a file, or simply manipulated as a stream of data.
See uses from Wiki :. The most obvious is that you can transmit the serialized class over a network, and the recepient can construct a duplicate of the original instanstance. Likewise, you can save a serialized structure to a file system.
Also, note that serialization is recursive, so you can serialize an entire heterogenous data structure in one swell foop, if desired. Serialized objects maintain state in space, they can be transferred over the network, file system, etc I use serialized objects to standardize the arguments I pass to functions or class constructors.
Passing one serialized bean is much cleaner than a long list of arguments. The result is code that is easier to read and debug. For the simple purpose of learning notice, I said learning, I did not say best, or even good, but just for the sake of understanding stuff , you could save your data to a text file on the computer, then have a program that reads that info, and based on the file, you could have your program respond differently.
If you were more advanced, it wouldn't necessarily have to be a txt file, but something else. Serializing on the other hand, puts things directly into computer language. It's like you're telling a Spanish computer something in Spanish, rather than telling it something in French, forcing it to learn French, then save things into its native Spanish by translating everything.
Not the most tech-intensive answer, I'm just trying to create an understandable example in a common language format. Serialization is also faster, because in Java, objects are handled on the heap, and take much longer than if they were represented as primitives on the stack.
Speed, speed, speed. And less file processing from a programmer point of view. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

And why haven't you accepted any answers to your questions?
He "wasn't convinced" they answered his questions. The answers provided were, in fact, correct. If they don't work for you, reply to them as comments and try to work it out instead of just ignoring them and then starting to flame others when they point out you're not using SO right. Anon is contributing to the quality of the site by discouraging duplicate questions. It's silly to see five separate questions that are all asking the same thing.
If you can't get an answer, well sometimes that's just how it is. If you get an answer but it doesn't seem to work, then continue the discussion in comments. Next Topic Transient Keyword in java.
