Used by You signed in with another tab or window. The logging threshold on the console is INFO , which means that you will see informational messages, warning messages and error messages on the console but not general debug messages.
In contrast, there is no threshold set for the server. However, be aware that just because the logging threshold allows debug messages to be displayed, that doesn't mean that all of JBoss will produce detailed debug information for the log file. You will also have to boost the logging limits set for individual categories. Take the following category for example.
This limits the level of logging to INFO for all JBoss classes, apart from those which have more specific overrides provided. This creates a new file appender and specifies that it should be used by the logger or category for the package org. The file appender is set up to produce a new log file every day rather than producing a new one every time you restart the server or writing to a single file indefinitely. The current log file is cmp.
Older files have the date they were written added to their filenames. Please note that the log directory also contains HTTP request logs which are produced by the web container.
Almost every aspect of the JBoss server can be controlled through the JMX Console, so it is important to make sure that, at the very least, the application is password protected. Otherwise, any remote user could completely control your server. To protect it, we will add a security domain to cover the application. This can be done in the jboss-web. Uncomment the security-domain in that file, as shown below.
This links the security domain to the web application, but it doesn't tell the web application what security policy to enforce, what URLs are we trying to protect, and who is allowed to access them.
To configure this, go to the web. This security constraint will require a valid user name and password for a user in the JBossAdmin group. That's great, but where do the user names and passwords come from? They come from the jmx-console security domain we linked the application to. This configuration uses a simple file based security policy.
The existing file creates an admin user with the password admin. For security, please either remove the user or change the password to a stronger one. You can check the server console to verify that JBoss has seen your changes. If you have configured everything correctly and re-deployed the application, the next time you try to access the JMX Console, it will ask you for a name and password.
There is also the Web Console. Although it's a Java applet, the corresponding web application can be secured in the same way as the JMX Console. The only real difference between the two is that editing the files inside the WAR file is a bit more cumbersome. The non-core, hot-deployable services are added to the deploy directory.
You can use the ones that are provided or write your own if you have more specific requirements. There are a number of implementation features that you should be aware of when developing applications for JBoss Application Server 5.
JBoss Application Server 4. This had certain implications for application development. We use two examples in this book:. We will see how to build this example using the build. We will also cover in detail the workings of the. Using a simple "TODO" application we will illustrate how Seam ties together the database, the web interface and the EJB3 business logic in a web application.
We will use the build. To compile and package the examples, you must have Apache Ant 1. You can do this by adding the following line to your. Add a semicolon and the path to the ant bin directory.
Verify your Ant installation. To do this type ant -version at the command prompt. Your output should look something like this:. Each 'todo' item has a 'title' and a 'description'. When you submit the form, the application saves your task to a relational database.
Entity objects - These objects represent the data model; the properties in the object are mapped to column values in relational database tables. JSF web pages - The web interface used to capture input data and display result data. We make use of a Stateless Session Bean. Let's take a look at the contents of the Data Model represented by the Todo class in the Todo. Each instance of the Todo class corresponds to a row in the relational database table.
The 'Todo' class has three properties: id, title and description. Each of these correspond to a column in the database table. This eliminates the need for XML configuration and makes it a lot clearer. The Entity annotation defines the Todo class as an Entity Bean. The Id and GeneratedValue annotations on the id property indicate that the id column is the primary key and that the server automatically generates its value for each Todo object saved into the database.
In this section we will show you how the web interface is defined using JSF pages. Lets take a look at the pages used in our application:. Create New Todo 2. Show all Todos. When you click on the Submit button the corresponding action is invoked. We use the todoBean to back the form input text fields. This method creates the "Todo" instance with the input data title and description and persists the data.
Figure There is also an option to choose a "todo" item for 'edit' or 'delete'. The 'Edit' option is available across each row. EJB 3. It aims at reducing the complexity of older versions of EJB and simplifies Enterprise Java development and deployment. You will notice that to declare a class as a 'Session Bean' you simply have to annotate it.
Using annotations eliminates the complexity involved with too many deployment descriptors. Also the only interface an EJB3 Session Bean requires is a business interface that declares all the business methods that must be implemented by the bean.
We will explore the two important source files associated with the Bean implementation in our application: TodoDaoInt. Business interface : TodoDaoInt. We define here the methods that need to be implemented by the bean implementation class. Basically, the business methods that will be used in our application are defined here. Stateless Session Bean : TodoDao. The Stateless annotation marks the bean as a stateless session bean. In this class, we need to access the Entity bean Todo defined earlier.
For this we need an EntityManager. The PersistenceContext annotation tells the JBoss Server to inject an entity manager during deployment. We will build the sample application using Ant and explore the configuration and packaging details. Please install Ant if currently not installed on your computer. Let's look at building the example application and then explore the configuration files in detail.
In Chapter 10, About the Example Applications , we looked at the directory structure of the jsfejb3 sample application.
At the command line, go to the jsfejb3 directory. There you will see a build. This is our Ant build script for compiling and packaging the archives. To build the application, you need to first of all edit the build.
Once you have done this, just type the command ant and your output should look like this:. The web source HTML, images etc. These include the deployment descriptors web. It also contains an additional descriptor, application. It is also possible to deploy EJBs and web application modules individually but the EAR provides a convenient single unit. Now that we have built the application, lets take a closer look at some of the important Configuration files.
We have built the final archive ready for deployment - jsfejb3. The contents of your EAR file should look like this:. The root URL for the application is also specified in this file as 'context-root'. In our case, we use the application name 'jsfejb3' as the class loader name.
In addition, the persistence. It contains all the web pages and the required configuration files. The web. It is the web deployment descriptor file. The faces-config.
