In Relation To...  Updated OGM kitchensink example - 0 views

  • jboss-as-maven-plugin to deploy the webapp. Unfortunately, this plugin does not allow me to start and stop the server and it seems redundant to require a local install if the Arquillian tests already download an AS instance (yes, I could run the test against the local instance as well, but think for example continuous integration where I want to manage/control the WHOLE ENVIRONMENT).
  • cargo plugin another go. A lot has happened there and it supports not only JBoss 7.x, but it also offers a so called artifact installer which allows to download the app server as a managed maven dependency.
  • cargo:install in the initialize phase to install the app server into the target directory. This way I can install a custom module (via the gmaven plugin) before the tests get executed and/or before I start the application

Chapter 6. Messaging (Gravity) - 0 views

  • Granite Data Services provides a messaging feature, code name Gravity, implemented as a Comet-like service with AMF3 data polling over HTTP (producer/consumer based architecture)
  • GraniteDS messaging relies on two main AS3 components on the Flex side: org.granite.gravity.Consumer and org.granite.gravity.Producer
  • 6.3. Common Configuration There are three main steps to configure Gravity in an application: Declare the Gravity servlet implementation for your target server in web.xml Declare a messaging service and destination in services-config.xml, mapped to a specific channel definition of type GravityChannel
  • ...10 more annotations...
  • org.granite.gravity.tomcat.GravityTomcatServlet
  • /gravityamf/*
  • 6.3.1. Supported Application Servers
  • GraniteDS provides a generic servlet implementation that can work in any compliant servlet container
  • blocking IO and thus will provide relatively limited scalability
  • GraniteDS thus provides implementations of non blocking messaging for the most popular application servers.
  • asynchronous non blocking servlets
  • JBoss 5+org.granite.gravity.jbossweb.GravityJBossWebServletOnly with APR/NIO enabled (APR highly recommended)
  • GlassFish 3.xorg.granite.gravity.async.GravityAsyncServletUsing Servlet 3.0
  • Tomcat 7.x / Jetty 8.xorg.granite.gravity.async.GravityAsyncServletUsing Servlet 3.0

  • java.util.Date, java.util.Calendar, java.sql.Timestamp, java.sql.Time, java.sql.Date
  • ...19 more annotations...
  • Object (generic)
  • java.util.Map
  • Array (dense)
  • java.util.List
  • List becomes ArrayList SortedSet becomes TreeSet Set becomes HashSet Collection becomes ArrayList
  • Array (sparse) java.util.Map java.util.Map
  • java.util.Map If a Map interface is specified, creates a new java.util.HashMap for java.util.Map and a new java.util.TreeMap for java.util.SortedMap.
  • BlazeDS passes an instance of java.util.ArrayList to parameters typed with the java.util.List interface and any other interface that extends java.util.Collection. Then these types are
  • sent back to the client as mx.collections.ArrayCollection instances
  • If you require normal ActionScript Arrays sent back to the client, you must set the legacy-collection element to true in the serialization section of a channel-definition's properties; for more information, see Configuring AMF serialization on a channel.
  • legacy-collection Default value is false. When true, instances of
  • java.util.Collection
  • are returned as
  • ActionScript Arrays
  • legacy-map Default value is false. When true, java.util.Map instances are serialized as an ECMA Array or associative array instead of an anonymous Object.
  • A typical reason to use custom serialization is to avoid passing all of the properties of either the client-side or server-side representation of an object across the network tier.
  • standard serialization scheme, all public properties are passed back and forth between the client and the server.
  • Explicitly mapping ActionScript and Java objects
  • Private properties, constants, static properties, and read-only properties, and so on, are not serialized

Why I will use Java EE instead of Spring in new Enterprise Java Projects in 2012 - Java... - 0 views

  • J2EE was horrible
  • This is why the Spring framework was created
  • It was lightweight, easy to use, and applications could be deployed in a web container (such as Tomcat) instead of a heavy J2EE application server
  • ...5 more annotations...
  • Pros and Cons of JEE and Spring
  • Advantages of JEE
  • set of standard specifications, thus it is vendor-independent
  • testing is possible!
  • Lightweight application servers and frameworks such as Arquillian arrived

Chapter 15. Data Management - 0 views

  • Data Management
  • Tide provides an integration between the Flex/LCDS concept of managed entities and the server persistence context (JPA or Hibernate)
  • Tide maintains a client-side cache of entity instances and ensures that every instance is unique in the Flex client context
  • ...5 more annotations...
  • highly recommended to use JPA optimistic locking in a multi-tier environment (@Version annotation)
  • Tip The easiest and recommended way for getting Tide enabled managed entities is to generate them from Java classes with Gas3 or the GDS Eclipse builder using the tide="true" option.
  • In a typical Flex/app server/database application, an entity lives in three layers: the Flex client the Hibernate/JPA persistence context the database
  • only invariant is the id.
  • id reliably links the different existing versions of the entity in the three layers

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.

Properties - 0 views

  • Automatic Property Setting
  • Subversion administrators commonly ask if it is possible to configure, on the server side, a set of property definitions which all connecting clients will automatically consider when operating on working copies checked out from that server. Unfortunately, Subversion doesn't offer this feature. Administrators can use hook scripts to validate that the properties added to and modified on files and directories match the administrator's preferred policies, rejecting commits which are non-compliant in this fashion. (See the section called “Implementing Repository Hooks” for more about hook scripts.) But there's no way to automatically dictate those preferences to Subversion clients beforehand.

Chapter 10. Integration with CDI - 0 views

  • Chapter 10. Integration with CDI
  • GraniteDS provides out-of-the-box integration with CDI via the Tide API
  • GraniteDS also integrates with container security for authentication and role-based authorization
  • ...37 more annotations...
  • always have to include this library in either WEB-INF/lib
  • support for CDI is included in the library granite-cdi.jar
  • 10.1. Configuration with Servlet 3 On Servlet 3 compliant containers, GraniteDS can use the new APIs to automatically register its own servlets and filters and thus does not need any particular configuration in web.xml. This automatic setup is triggered when GraniteDS finds a class annotated with @FlexFilter in one of the application archives:
  • @FlexFilter(configProvider=CDIConfigProvider.class) public class GraniteConfig { }  
  • list of annotation names that enable remote access to CDI beans
  • ConfigProvider
  • override these values by setting them in the annotation properties
  • tide=true,         type="cdi",         factoryClass=CDIServiceFactory.class,         tideInterfaces={Identity.class}
  • @FlexFilter declaration will setup an AMF processor for the specified url pattern
  • tideAnnotations
  • defines suitable default values
  • @TideEnabled
  • @RemoteDestination
  • always declared by default
  • tideInterfaces
  • tideRoles
  • exceptionConverters
  • amf3MessageInterceptor
  • 10.3.2. Typesafe Remoting with Dependency Injection
  • It is possible to benefit from even more type safety by using the annotation [Inject] instead of In. When using this annotation, the full class name is used to find the target bean in the CDI context instead of the bean name.
  • Security
  • integration between the client RemoteObject credentials and the server-side container security
  • client-side component named
  • identity
  • API to define runtime authorization checks on the Flex UI
  • login()

  • We use
  • GMT + 0
  • for AMF for convention
  • define a
  • fixed timezone
  • for your AMF that is over HTTP
  • GMT + X
  • : timezone for your flex client
  • GMT + Y
  • : timezone for your server
  • don't want to modify the default templates
  • override the readExternal / writeExternal methods and do the conversion here.
  • The patch is to use a custom template for generating your as files with a conversion to GMT 0 in the implementations of IExternalizable methods.On the server-side you add a Converter to convert dates GMT 0 to dates GMT + Y.

7. Tide Framework - Confluence - 0 views

  • GDS/Tide project represents the Data Services part of GDS
  • comparable to LiveCycle Data Services, which is neither open source nor free, as it provides similar features such as client container of managed entities, data paging, and integration with server components, but it is based on completely different principles:
  • strongly typed Hibernate/JPA detached objects
  • ...5 more annotations...
  • All managed entity instances are unique in a Tide context
  • Tide keeps the classic three layers web architecture, when LCDS removes the service layer, and is some kind of remote JPA provider for Flex applications
  • Tide approach is to minimize the amount of code needed to make things work between the client and the server
  • principles are very similar to the ones of JBoss Seam, which is the main reason why the first integration of Tide has been done with this framework. Integrations with Spring, EJB 3 and CDI are also available
  • need to compile your MXML/AS sources with the granite-essentials.swc and granite.swc libraries

Chapter 10. Integration with CDI - 0 views

  • 10.3.5. Security GraniteDS provides a client-side component named identity that ensures the integration between the client RemoteObject credentials and the server-side container security. It additionally includes an easy-to-use API to define runtime authorization checks on the Flex UI.
  • CDI identity component (of class org.granite.tide.cdi.Identity) predictably provides two methods login() and logout()
  • identity component is integrated with server-side role-based security and can be used to get information or show/hide UI depending on the user access rights:
  • ...2 more annotations...
  •  enabled="{identity.hasRole('admin')}"

Interview of GraniteDS founders | RIAgora - 0 views

  • explained the origin of GraniteDS and the differences with LiveCycle Data Services
  • ActionScript3 reflection API
  • GraniteDS 2.2
  • ...8 more annotations...
  • JSR-303 (“Bean Validation”) ActionScript3 framework for form validation
  • validation framework is a specific adaptation of the JSR-303 (Bean Validation) specification to Flex: like its Java counterpart, it relies on validation annotations placed on bean properties and provides an engine API that lets you validate your forms without writing by hand a specific validator for each of your input fields
  • code generation tools provided by GraniteDS so that when you write your Java entity bean with validation annotations, they are automatically replicated in your ActionScript3 beans
  • problem with LCDS is mainly that it promotes a strict “client / server” architecture, with – roughly speaking – a heavy Flex client application connected to a server almost reduced to a database frontend
  • big majority of  these organizations use BlazeDS, a free and open-source subset of LCDS
  • need more advanced mechanisms than just Remoting start looking for open-source libraries to enable deeper integrations with the Java business layer, and GraniteDS is for sure the most popular project
  • “Flex Data Services” (now renamed to “Live Cycle Data Services”)
  • Flex Data Services seemed too “client-centric”

Article Series: Migrating Spring Applications to Java EE 6 - Part 1 | How to JBoss - 1 views

  • In fact people still love those books without realizing that the world has changed dramatically ever since
  • The reality check here is to wonder whether the rhetorics set forth by Rod Johnson in his 2003/2004 books are still actual today
  • So if you still care about those books, the best way to show your appreciation is probably to use them as your monitor stand
  • ...21 more annotations...
  • The discussion whether or not to use Spring vs. Java EE for new enterprise Java applications is a no-brainer
  • Why migrate?
  • since then fallen a prey to the hungry minds of Venture Capitalists and finally into the hands of a virtualization company called VMware
  • While the different companies and individuals behind the Spring framework have been doing some work in the JCP their voting behavior on important JSRs is peculiar to say the least
  • outdated ORM solution like JDBC templates
  • some developers completely stopped looking at new developments in the Java EE space and might have lost track of the current state of technology
  • size of the deployment archive
  • fairly standard Java EE 6 application will take up about 100 kilobytes
  • comparable Spring application weighs in at a whopping 30 Megabytes!
  • Lightweight
  • Firing up the latest JBoss AS 7 Application Server from scratch and deploying a full blown Java EE 6 application into the server takes somewhere between two and five seconds on a standard machine. This is in the same league as a Tomcat / Spring combo
  • Dependency injection
  • Java EE 6, the Context and Dependency Injection (CDI) specification was introduced to the Java platform, which has a very powerful contextual DI model adding extensibility of injectable enterprise services
  • Aspect Oriented Programming
  • “AOP Light” and this is exactly what Java EE Interceptors do
  • common pitfall when taking AOP too far is that your code might end up all asymmetric and unreadable. This is due to the fact that the aspect and its implementation are not in the same place. Determining what a piece of code will do at runtime at a glance will be really hard
