"javaCodebase" should contain the URL of a codebase directory or a JAR file. In the latter case, Oracle's LDAP service provider will automatically use the attribute to load the class definitions as needed. Or you can use the "javaCodebase" attribute specified in. You can use any attribute to record this codebase and have your application read that attribute from the directory and use it appropriately. 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.Īlternatively, 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 usingĭirContext.modifyAttributes. These procedures might not be generally applicable to other naming and directory services that support binding a serializable object with a specified codebase. Note: The procedures described here are for binding a serializable object in a directory service that follows the schema defined in To associate attributes with the new binding, you useĭirContext.bind. You can store a serializable object in the directory if the underlying service provider supports that action, as does Oracle's LDAP service provider.Ĭontext.bind to bind an AWT button to the name "cn=Button". For example, a Java application might include in its classpath a JAR file that contains the class files of the serialized object(s) or load the class definitions by using information stored in the directory, as explained later in this lesson. It is the responsibility of the system that is deserializing the object to determine how to locate and load the necessary class files. However, the class's definition ("class file") itself is not recorded. When an object is serialized, information that identifies its class is recorded in the serialized stream. Object Serialization Specification describes object serialization in detail. A (Java) class can override this default serialization and define its own way of serializing objects of that class. The Java platform specifies a default way by which serializable objects are serialized. Later, you can read back the serialized state and deserialize into a object. Deserialization is the process of converting the serialized form of an object back into a copy of the object.įor example, the class implements the Serializable interface, so you can serialize a object and store that serialized state in a file. A Java object is serializable if its class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externalizable. Implementation platform(" serialize an object means to convert its state to a byte stream so that the byte stream can be reverted back into a copy of the object. LibraryDependencies += "" %% "akka-actor" % AkkaVersion Maven To use Serialization, you must add the following dependency in your project: sbt val AkkaVersion = "2.8.4" sbt resolvers += "Akka library repository".at("") To access them there, you need to configure the URL for this repository. The Akka dependencies are available from Akka’s library repository.
