I. Introduction of the ContentJava EE's 13 core technologies: JDBC, JNDI, EJB, RMI, JSP, Java Servlet, XML, JMS, Java IDL, JTS, JTA, JavaMail, and JAF.Java was initially in the browser and client machines, when many questioned whether it was suitable for server-side development. Now with the increase in support for third-party Java EE, Java is widely accepted as one of the preferred platforms for developing

. 12, JavaMailJavaMail is used to access the mail server API, it provides a set of abstract classes for mail server . not only support SMTP Server , also supports IMAP Server . 13, JAF (JavaBeans activationframework)JavaMail uses JAF to handle MIME-encoded message attachments. MIME byte streams can be converted to Java objects, and most applications do not have to use the J AF. Summarize:The 13 specificatio

It supports both point-to-point domains, domains that support publish/subscribe (Publish/subscribe) types, and provides support for the following types of messages: Approved messaging, transactional message delivery, consistent messaging, and persistent subscriber support.

Having learned about the Java EE recently, it is mentioned that the study of this project has to mention its 13 specifications:The Java EE platform consists of a suite of services, application interfaces (APIs), and protocols that provide functional support for developing Web-based multi-tier applications, with a simple description of the

Java EE Presumably everyone is not strange, it seems that now more popular to call it Java EE, no matter how the name changed, the core and the idea is unchanged. Learn the Java EE first to understand its specifications, let's look at its 13 specifications.1,JDBC (Java Database Connectivity)The Java API for executing S

The Java EE platform consists of a suite of services, application interfaces (APIs), and protocols that provide functional support for the development of Web-based multi-tier applications, with a simple description of the 13 technical specifications in the Java EE (Space-constrained, simple description only):1.JDBC (Java Database Connectivity): The JDBC API provi

can be deployed to any Web service application in an axis environment that needs to be implemented ws-security. At the same time the specific application does not make any coding modifications. Since this is based on handler implementations, it is necessary to review some of the basics of handler. SOAP messages handler have access to SOAP messages that represent RPC requests or responses. In Jax-RPC technology, SOAP message Handler can be deployed on the server or used on the client. SOAP messa

;Variable type When you run the shell, there are three different variables: Local VariablesA local variable is defined in a script or command and is valid only in the current shell instance. Environment variablesAll programs, including shell-initiated programs, can access environment variables, and some programs require environment variables to keep them running properly. Shell scripts can also define environment variables when necessary. Shell variablesShell variables are special variable
