best strategies for implementation of equals() and hashcode() in your persistent classes

The general contract is: if you want to store an object in a List, Map or a Set then it is an requirement that equals and hashCode are implemented so they obey the standard contract as specified in the  documentation

Why are equals() and hashcode() importantNormally, most Java objects provide a built-in equals() and hashCode() based on the object's identity; so each new() object will be different from all others.

JTA transactions are

implicitly defined through SessionBean usage/methods. In a SessionBean normally each SessionBean method invocation defines a JTA transaction.

differences between CDI beans and EJBs is that EJBs are : Transactional Remote or local Able to passivate stateful beans freeing up resources Able to make use of timers Can be asynchronous

Stateless EJBs can be thought of as thread safe single-use beans that don’t maintain any state between two web requests

Stateful EJBs do hold state and can be created and sit around for as long as they are needed until they are disposed of

key ingredients of a service-oriented component: Facade: Provides simplified, centralized access to the component and decouples the client from the concrete services. It is the network and transaction boundary. Service: The actual implementation of business logic. Domain structure: This is a structure rather than an object. It implements the component's persistence and exposes all of its state to the services, without encapsulation.

This convention not only standardizes the structure and improves maintainability, but also allows automatic dependency validation with frameworks like JDepend, Checkstyle,  Dependometer, SonarJ, or XRadar. You can even perform the validation at build time. If you do, the continuous build would break on violation of defined dependencies. The rules are clearly defined with strict layering: a facade may access a service, and the service a domain object, but not vice versa

A Realm is a component that can access application-specific security data such as users, roles, and permissions. The Realm translates this application-specific data into a format that Shiro understands so Shiro can in turn provide a single easy-to-understand Subject programming API no matter how many data sources exist or how application-specific your data might be.

A Realm is essentially a security-specific DAO

Spring Security Dependencies

This appendix provides a reference of the modules in Spring Security and the additional dependencies that they require in order to function in a running application

C.1 spring-security-coreThe core module must be included in any project using Spring Security.

EJB beans cannot be directly exposed to JSF or JSP without a little help from CDI

CDI doesn't provide any transactional, monitoring, or concurrency aspect out of the box

The configuration of a GraniteDS project will generally involve the following steps : Add the GraniteDS jars to the WEB-INF/lib folder of the WAR file or the lib folder of the EAR file Add the GraniteDS listener, servlets and filters in the standard WEB-INF/web.xml configuration file Define the internal configuration of GraniteDS in the WEB-INF/granite/granite-config.xml file Define the application configuration of GraniteDS (remoting destinations, messaging topics...) in the WEB-INF/flex/services-config.xml

You will always need granite.jar

jar for your JPA provider (granite-hibernate.jar for Hibernate)

ComparisonThis section provides a brief comparison of SAFs functionality with that of the Acegi Security Framework [11] and JBoss Seam Security [12]

Acegi’s Policy Decision functionality is not based on Java security standards but on a proprietary solution

ACL defines per domain object who has access permissions

previously known as the JSecurity project

The word Subject is a security term that basically means "the currently executing user"

Core Concepts: Subject, SecurityManager, and Realms

Links in Confluence will not break even when you rename pages or move them between spaces on your site. Confluence will rename the links, provided you have inserted them as relative links, not as full URLs.

DeltaSpike will consist of a number of portable CDI extensions that provide useful features for Java application developers

Bean Validation for Flex developers

GraniteDS have added support for Bean Validation into their project and hence Bean Validation is usable by all Flex users

Because they do not run on the JVM, they basically have reimplemented the full specification in Flex: you can annotate your ActionScript3 objects with constraints: it supports all the standard constraints and you can write your own constraints you can execute the validation logic and retrieve the error report you can make use of most of the feature including advanced ones like groups, group sequence etc

The quickstarts demonstrate JBoss AS 7, Java EE 6 and a few additional technologies. They provide small, specific, working examples that can be used as a reference for your own project

Troubleshooting The org.jboss.as.jpa logging can be enabled to get the following information: INFO - when persistence.xml has been parsed, starting of persistence unit service (per deployed persistence.xml), stopping of persistence unit service DEBUG - informs about entity managers being injected, creating/reusing transaction scoped entity manager for active transaction TRACE - shows how long each entity manager operation took in milliseconds, application searches for a persistence unit, parsing of persistence.xml

Integration with Seam 2.2

GraniteDS provides out-of-the-box integration with Seam 2.2 via either the RemoteObject API or the Tide API to remotely call Seam components, and fully supports serialization of JPA entities from and to your Flex application, taking care of lazily loaded associations

What is flex-mojos? A collection of maven plugins to allow maven to compile, optimize, and test Flex SWF, Flex SWC, Air SWF, Air SWC and Air package The main goal is to provide full support to all mxmlc/compc options.
