  • Container-Independent Clustering!
  • Heterogeneous Client Access
  • Event Listeners

  • Can be used for SSO
  • easily stored in any data source
  • can be
  • 'shared'
  • across applications if needed
  • 'poor man's SSO'

Chapter 2. Mapping Entities - 0 views

  • map multiple properties as @Id properties
  • annotated the property as
  • map multiple properties as @Id properties and declare an external class to be the identifier type
  • declared on the entity via the @IdClass annotation
  • The identifier type must contain the same properties as the identifier properties of the entity: each property name must be the same, its type must be the same as well if the entity property is of a
  • basic type
  • last case is far from obvious
  • recommend you not to use it (for simplicity sake)
  • @EmbeddedId property
  • @EmbeddedId
  • @Embeddable
  • @EmbeddedId
  • @Embeddable
  • @Embeddable
  • @EmbeddedId
  • Multiple @Id properties
  • arguably more natural, approach
  • place @Id on multiple properties of my entity
  • only supported by Hibernate
  • does not require an extra embeddable component.
  • @IdClass
  • @IdClass on an entity points to the class (component) representing the identifier of the class
  • WarningThis approach is inherited from the EJB 2 days and we recommend against its use. But, after all it's your application and Hibernate supports it.
  • Mapping entity associations/relationships
  • One-to-one
  • three cases for one-to-one associations:
  • associated entities share the same primary keys values
  • foreign key is held by one of the entities (note that this FK column in the database should be constrained unique to simulate one-to-one multiplicity)
  • association table is used to store the link between the 2 entities (a unique constraint has to be defined on each fk to ensure the one to one multiplicity)
  • @PrimaryKeyJoinColumn
  • shared primary keys:
  • explicit foreign key column:
  • @JoinColumn(name="passport_fk")
  • foreign key column named passport_fk in the Customer table
  • may be bidirectional
  • owner is responsible for the association column(s) update
  • In a bidirectional relationship, one of the sides (and only one) has to be the owner
  • To declare a side as
  • not responsible for the relationship
  • the attribute
  • mappedBy
  • is used
  • mappedBy
  •  Indexed collections (List, Map)
  • Lists can be mapped in two different ways:
  • as ordered lists
  • as indexed lists
  • @OrderBy("number")
  • List<Order>
  • List<Order>
  • List<Order> 
  • To use one of the target entity property as a key of the map, use

  •  @MapKey(name"number")
  • Map<String,Order>
  • String number

  • @MapKeyJoinColumn/@MapKeyJoinColumns
  • if the map key type is another entity
  • @ManyToAny
  • 2.4.5.2. @Any
  • @Any annotation defines a polymorphic association to classes from multiple tables
  • this is most certainly not meant as the usual way of mapping (polymorphic) associations.
  • @ManyToAny allows polymorphic associations to classes from multiple tables
  • first column holds the type of the associated entity
  • remaining columns hold the identifier

Java EE wins over Spring « Bill the Plumber - 0 views

  • Spring is controlled by ONE COMPANY. It is not an independent open source organization like Apache. At least with Java EE there are multiple OPEN SOURCE implementations. How long before VMWare decides its $500 million investment needs to be recouped and they start charging for Spring in a big way? Don’t think it can happen? Think again…VMWare is in the same poor position BEA/WLS was against JBoss with Red Hat’s VM/Cloud tech eating away at VMWare’s margins. There is a much higher chance of them scrambling for revenue sources than Red hat ever being acquired by Oracle.

  • if you’ve heard Rod Johnson speak he is always adamant that Spring has replaced Java EE. Its good to see that his rhetoric is utter BS!
  • Sorry, even Spring MVC sucks as much balls as JSF does.
  • Java EE wins over Spring
  • CDI closed API hole
  • Application server started to get their act together with regards to boot time.  It started with Glassfish and ended with JBoss 7.  Both of which can boot in a matter of seconds.
  • Arquillian allows you to run your unit tests in a real environment with real transactions, etc.  Personally I always despised mocks because they didn’t test in the environment you were going to run in.  I thought they were pointless and to this day, I refuse to use this testing pattern.
  • I’m glad Rod and company were able to cash out with the VMWare acquisition before Java EE was able to regain its dominance
  • SpringSource pushed Java EE to innovate and for that I’m very grateful.  For Java EE, it was either evolve or die.  They evolved, now its time for Spring to die.

Data Source Configuration in AS 7 | JBoss AS 7 | JBoss Community - 0 views

  • Data Source Configuration in AS 7
  • Using @DataSourceDefinition to configure a DataSource
  • This annotation requires that a data source implementation class (generally from a JDBC driver JAR) be present on the class path (either by including it in your application, or deploying it as a top-level JAR and referring to it via MANIFEST.MF's Class-Path attribute) and be named explicitly.
  • ...21 more annotations...
  • this annotation bypasses the management layer and as such it is recommended only for development and testing purposes
  • Defining a Managed DataSource
  • Installing a JDBC driver as a deployment
  • Installing the JDBC Driver
  • deployment or as a core module
  • managed by the application server (and thus take advantage of the management and connection pooling facilities it provides), you must perform two tasks.  First, you must make the JDBC driver available to the application server; then you can configure the data source itself.  Once you have performed these tasks you can use the data source via standard JNDI injection.
  • recommended way to install a JDBC driver into the application server is to simply deploy it as a regular JAR deployment.  The reason for this is that when you run your application server in domain mode, deployments are automatically propagated to all servers to which the deployment applies; thus distribution of the driver JAR is one less thing for administrators to worry about.
  • Note on MySQL driver and JDBC Type 4 compliance: while the MySQL driver (at least up to 5.1.18) is designed to be a Type 4 driver, its jdbcCompliant() method always return false. The reason is that the driver does not pass SQL 92 full compliance tests, says MySQL. Thus, you will need to install the MySQL JDBC driver as a module (see below).
  • Installing a JDBC driver as a module
  • <module xmlns="urn:jboss:module:1.0" name="com.mysql">  <resources>    <resource-root path="mysql-connector-java-5.1.15.jar"/>  </resources>  <dependencies>    <module name="javax.api"/>  </dependencies></module>
  • jboss-7.0.0.<release>/modules/com/mysql/main
  • define your module with a module.xml file, and the actual jar file that contains your database driver
  • content of the module.xml file
  • Under the root directory of the application server, is a directory called modules
  • module name, which in this example is com.mysql
  • where the implementation is, which is the resource-root tag with the path element
  • define any dependencies you might have.  In this case, as the case with all JDBC data sources, we would be dependent on the Java JDBC API's, which in this case in defined in another module called javax.api, which you can find under modules/javax/api/main as you would expect.
  • Defining the DataSource itself
  •    <datasource jndi-name="java:jboss/datasources/MySqlDS" pool-name="MySqlDS">      <connection-url>jdbc:mysql://localhost:3306/EJB3</connection-url>         <driver>com.mysql</driver>
  •     <drivers>      <driver name="com.mysql" module="com.mysql">        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>      </driver>    </drivers>

  • JpaRealm
  • @PersistenceContext   private EntityManager entityManager;
  • EnvironmentLoaderListener
  • found the cause
  • Instead of configuring the ShiroFilter in my web.xml I had the IniShiroFilter configured. The IniShiroFilter creates a new SecurityManager from the ini file. This new SecurityManager didn't know about the realm I've added in my EnvironmentLoader, so it didn't have any realms.
  • I replaced it with the ShiroFilter in my web.xml and all seems to be working now with my CdiEnvironmentLoaderListener.
