JBOSS series -- Cluster -- basic configuration (1) -- client,1. What is a cluster?
A cluster is a set of computer nodes that provide users with a set of network resources as a whole. The ideal cluster is transparent to users. Users can access the cluster resources from a single portal without realizing the existence of the cluster. You can add or reduce nodes to clusters without affecting user access.

Let's take a look at this file. Both the user name and password are stored in plain text, which brings great security to the system. Therefore, we need to add a password for our plaintext password. This is the purp
Configure the JBoss Data Source
Why do I need to configure the JBoss data source in JBoss? This is actually a manifestation of the object-oriented thinking: access to the database through container management.
At first, we accessed the database through JDBC, and we created all the connections and commands. However, every time you open and close the database, it c
When you use EJB3.0 Session bean and message-driven bean (as well as other Java EE5.0 standards), Java Persistence is beginning to reveal its strength. The EJB3.0 specification has been designed to allow persistent integration, because you can obtain Automatic Transaction Division within the Bean method range, or a persistent context (such as Session) that spans the state Session EJB lifecycle ).This article starts with EJB3.0 and JPA in a managed JavaEE environment. You will learn the basic kno

Assume that a Traveler wants to develop a good Java backend server on winter nights.
The so-called beauty is the high performance, tens of millions of users; high reliability, failover is still dead; high scalability, with the nearby tuxedo, ibm mq, WebService neighbors to deal well. This is a non-personalized requirement, almost every time.
The open-source world of Java has prepared Mina, cxf, mule, and
1. Unzip and install the Jboss container and start it. Access http: // localhost: 8080/jmx-console. If it is displayed as normal, the Jboss container is successfully started.
2. If Jboss is installed in the root directory of the D Drive, enter D:/jboss/server/default/deploy and create test. war directory, because the w
I did a performance test at the company. recently, it was relatively idle, so I simply studied the performance comparison between tomcat and jboss. I just did it. thanks to tomcat's familiarity, the environment was relatively mature, jboss is just getting in touch with this stuff, so it's a little raw, but I believe it's not big with tomcat...

IPv6 is a demand of the times, so many environments are not compatible with this new protocol. Now let's talk about how to support JBoss IPv6 in the network environment. For details, refer to our workshop. First, let's analyze several key points of implementation.
In the JBoss IPv6 network environment, IPv6 support mainly includes the following requirements:
1. Linux supports IPv6;
2. the Java Virtual Machi
Summary: JBoss seam is "a lightweight framework for Java EE 5.0". What does that mean? is Java EE (Enterprise Edition) 5.0 not a set of "frameworks" in itself? Why is there a need for another framework outside of the official norm? Well, let's think of seam as a "missing frame" that should have been included in Java EE 5.0. It is on the upper level of the Java EE 5.0 framework, providing a unified, easy-to-understand programming model for all componen

JBoss is a Redhat System Service-general Linux technology-Linux programming and kernel information. The following is a detailed description. How can JBoss be started when the Linux system is started?
Overall views
Use the V script of Linux. Although there are some differences between categories, it is usually similar to this:
/Etc/rc. d/init. d/-contains the start and stop scripts (other types:/etc/init.
Because development requires that the development environment be automatically deployed every night, it takes one day to write a jboss-based Automatic deployment script.
