Problems solved by technology

The choice of granularity has its own advantages and disadvantages. There is no essential difference in choosing a certain granularity, and the implementation difficulty is roughly the same. The design ideas of the response method of request call are quite different. At present, the two main methods have certain shortcomings, mainly including software. The architecture is not clear, the speed is not fast enough, the flexibility is poor, etc.

Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] Referring to the attached figure, after the application is deployed to the server, the container factory creates the corresponding EJB container through the factory method according to the application type, and deploys the EJB in the application into the EJB container. Each EJB container has a corresponding instance pool, instance buffer, and persistence manager, and ejb instances are stored in the instance pool and instance buffer. The following introduces the container, these four components and the ejb instance respectively:

[0012] 1. EJB container

[0013] The EJB container provides an environment for the running of ejb instances;

[0014] 2. Container factory

[0015] The function of the container factory is to create an EJB container and deploy the EJB to the EJB container. The deployment of EJB includes parsing the EJB in the EJB jar, and ...

Abstract

Using calling and pre-compilation mode, the disclosed method does not need of reflection mechanism so as to raise running speed greatly. Including a pre-compilation procedure for generating codes, the method puts some control logic into compiled codes so as to make structure of container as simple as possible. Since there is object of receiving request corresponding to each ejb instance, bottleneck like things caused by dynamic agent mode will not appear. EJBHome and EJBObject can be created before a client call is reached in order to save access time for client. Passivation can be carried out for an instance not utilized for long time in order to save system resource.

Description

technical field [0001] The invention relates to a method for realizing a J2EE platform. Background technique [0002] With the gradual completion of the transformation of the distributed application system from the two-tier structure model to the three-tier structure model and the rapid development of the Internet and e-commerce, the middleware software industry emerged as the times require. As the core software platform of the Internet-based network environment, it has become an integral part of the large-scale distributed application infrastructure. Among them, the application server middleware is becoming the three pillars of the basic software field alongside the operating system and database management system. The application server middleware adopts the latest multi-layer architecture, which involves operating system, network communication, distributed database, Internet and many other core technologies of the software industry (referred to as "operating system on the ...
