Put it this way, SOA is nothing more than Web Services and standardized middleware. In my opinion one of the biggest obstacle in the movement towards SOA adoption is the organization’s own IT department.Too many people in the IT organization conceive SOA as a technology concept only, and as such think of SOA as just a set of technologies and infrastructure for exposing, securing, running, and managing Services. How would you convince my IT department to adopt SOA? JBoss registers in the JNDI tree a JTA UserTransaction Object which can be user to manage a distributed transaction. How can you start a JTA transaction from a Servlet deployed on JBoss? It’s retrieved by the SessionFactory’s openSession() method. This interface is a single threaded object which represents a single unit of work with application and persistent database. The Session interface wraps a JDBC Connection. Which Hibernate object wraps the JDBC Connection? You may choose to distribute the data with JBoss Messaging to move it where it is needed for computation or event-based programming. It is based on JGroups and enables clustering and high availability of that data. JBossCache enables easy distribution of datasets across your computing environments. Seam runs beautifully on other application servers – just like everything else the Hibernate team does, this is not a JBoss-only thing. Does Seam run on other application servers besides JBoss? It is technically possible to put a JBoss server instance into multiple clusters at the same time, this practice is generally not recommended, as it increases the management complexity. Is it possible to put a JBoss server instance into multiple cluster at the same time? Using Joss JMX agents and monitoring the deployed components to the application server involves in the first step.Īfter finding the most of the time spent by specific components or libraries or most of the resources, one can use Jprobe a specialized tool for examining the single object or the objects loaded in the memory. This step is to find where the degradation is, whether it is external or internal and where is the appliciation spending all the time. How do you monitor JBoss and detect the bottleneck of an application?ĭifferent components of the application are to be measured. HTTP session replications (tc5-cluster-service.xml).It has all the libraries for clustering:.What do you need to set-up a cluster with JBoss?īasically starting JBoss with the “all” configuration contains everything needed for clustering: When configured in Domain mode, multiple servers are managed from a centralized point called Domain Controller which maintain the configuration and provisions applications for deployment on the single nodes which are part of the Domain When configured in Standalone mode each distribution starts a single JVM process with its own configuration, management instruments and deployments. What’s the difference between Standalone mode and Domain mode? This feature is provided by the JBoss jBPM process designer.
The business process is graphically represented to facilitate a strong link between the business analyst and technical developer. The combination of workflow applications development with process design is a feature of JBoss jBPM.
Enabling the creation of business processes that coordinates between people, applications and services is the functionality of BPM engine.
JBoss supports JNDI, Servlet/JSP (Tomcat or Jetty), EJB, JTS/JTA, JCA, JMS, Clustering (JavaGroups), Web Services (Axis), and IIOP integration (JacORB). It runs under any JVM of 1.3 or later versions. It was embedded with Apache Tomcat web server. Being JEE based, the JBoss supports cross-platform java applications. JBoss is a popular open source application server based on JEE technology.
