Jakarta Contexts and Dependency Injection (CDI) is a specification to provide a dependency injection container; Jakarta Enterprise Beans ( EJB ) specification defines a set of lightweight APIs that an object container (the EJB container) will support in order to provide transactions (using JTA ), remote procedure calls (using RMI or RMI-IIOP ...
Though not dependent on "language dependent Enterprise Java Beans (EJB)", it is a more general form of EJB, providing four component types instead of the two that EJB defines. It provides an abstraction of entities that can provide and accept services through well-defined named interfaces called ports .
RMI-IIOP (read as "RMI over IIOP") denotes the Java Remote Method Invocation (RMI) interface over the Internet Inter-Orb Protocol (IIOP), which delivers Common Object Request Broker Architecture (CORBA) distributed computing capabilities to the Java platform. It was initially based on two specifications: the Java Language Mapping to OMG IDL ...
The EJB 3.0 specification relies heavily on the use of annotations (a feature added to the Java language with its 5.0 release) and convention over configuration to enable a much less verbose coding style. Accordingly, in practical terms EJB 3.0 is much more lightweight and nearly a completely new API, bearing little resemblance to the previous ...
A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
Code injection is the malicious injection or introduction of code into an application. Some web servers have a guestbook script, which accepts small messages from users and typically receives messages such as: Very nice site! However, a malicious person may know of a code injection vulnerability in the guestbook and enter a message such as:
EJB QL is a database query language similar to SQL. The used queries are somewhat different from relational SQL, as it uses a so-called "abstract schema" of the enterprise beans instead of the relational model. In other words, EJB QL queries do not use tables and their components, but enterprise beans, their persistent state, and their ...
Method Injection, where dependencies are provided to a method only when required for specific functionality. Setter injection, where the client exposes a setter method which accepts the dependency. Interface injection, where the dependency's interface provides an injector method that will inject the dependency into any client passed to it.
