For Linux, the path separator is a colon; for Windows, the path separator is a semicolon. This means that it is possible for a deployment to import classes from another deployment using the other deployment's module name; the details of how to add an explicit module dependency are explained below. Class Loading Precedence A common source of errors in Java applications is including API classes in a deployment that are also provided by the container. This can result in multiple versions of the class being created and the deployment failing to deploy properly.
To prevent this in JBoss EAP, module dependencies are added in a specific order that should prevent this situation from occurring. In order of highest priority to lowest priority: System Dependencies: These are dependencies that are added to the module automatically by the container, including the Java EE APIs. User Dependencies: These are dependencies that are added through jboss-deployment-structure. Local Resource: Class files packaged up inside the deployment itself, e.
Interdeployment dependencies: These are dependencies on other deployments in an EAR deployment.
All classes packaged in the WAR will be loaded with the same class loader. This means that not all classes inside an EAR will necessarily have access to all other classes in the EAR, unless explicit dependencies have been defined.
This behavior is controlled via the ear-subdeployments-isolated attribute in the EE subsystem configuration. By default, this is set to false, which allows the sub-deployments to see classes belonging to other sub-deployments within the EAR.
For example, consider the following EAR deployment: example. Similarly, classes from ejb1. If the ear-subdeployments-isolated is set to true, then no automatic module dependencies between the sub-deployments are set up. You must manually set up the dependencies with Class-Path entries or set up explicit module dependencies. This is per the specification. It is also possible to override the ear-subdeployments-isolated element value at a per-deployment level in the jboss-deployment-structure.
It then moves into the practical steps necessary for installing JBoss AS 7. The chapter goes beyond basic installation which amounts to uncompressing archive files to discuss starting and stopping JBoss AS 7 and using Command Line Interface CLI to connect to it locally and remotely. The initial chapter also discusses installation of Eclipse "the development environment used in this book".
One of my favorite parts of this initial chapter is its coverage of the application server's directory structure and differentiation of JBoss AS 7's "standalone servers and domain servers. This chapter had some surprises for me, including starting with this: "The application configuration has also been renewed, moving from a large set of XML files to a single monolithic file.
It goes through the configuration file one major section at a time, detailing how to configure the server in each area.
There is quite a bit in this chapter on configuring logging. Another thing I learned here that has changed in JBoss in recent years is default use of its own logging framework.

Chapter 3: Configuring Enterprise Services The third chapter is on configuring enterprise services. This chapter specifically focuses on configuring database connectivity, EJB container, messaging service, and transaction service. I liked how this chapter compared and contrasted how database configuration was performed in previous versions of JBoss AS to how it is now done in JBoss AS 7.
The chapter demonstrates XML-based configuration of a data source and how it was similar to that used in previous versions of the JBoss application server , but then also shows how to use the Java EE 6 annotation DataSourceDefinition to programmatically configure the data source in conjunction with an EJB 3.
The chapter discusses in detail how to configure the different types of EJBs. It then explains how to configure the JTA support for timeouts and statistics gathering.
The chapter also demonstrates adding JPA -based persistence including how to switch the JPA provider from default Hibernate 4 , setting a custom web context, and deploying the web application.
I also found the author's use of VisualVM to be helpful. This detailed chapter introduces domain terminology, explains what a domain is, and explains why a domain does not provide the same functionality or purpose as node clustering.
It provides thorough detail on configuring domains. I was happy to see coverage of using CLI to deploy from the command line, but fans of deploying via web page will be happy to know that there is also coverage of deploying from the web administration console.
The chapter also demonstrates deploying from the Eclipse IDE. The most significant bane of my Java development experience has probably been classloaders , which become tricky when application servers, IDEs, and frameworks like Spring are involved. With this in mind, I was happy to see a section in the sixth chapter called "JBoss AS 7 classloading explained.
MF file. The first section talks about CLI support for a group of commands as an atomic unit and the second section talks about writing file-based administration scripts.
Although I find that I use command line-based tools for configuration, administration, and deployment of an application server in the long-run, web-based or other graphically-oriented tools are often nice when first using an application server or when trying to figure new things out.
In other words, I prefer command line scripting for routine tasks and prefer graphically-oriented administrative tools for new or unusual tasks. The second half of Chapter 7 covers using "The new Web admin console.
The chapter points out the advantages and limitations of the jmx-console approach versions of JBoss up to JBoss 4.
As one would expect, the section on Web admin console is filled with screen snapshots demonstrating the Web admin console in action.Exploring the application server file system. Deploying Applications.
