Chapter 6. Messaging (Gravity) - 0 views

graniteds messaging Gravity JMS ProducerConsumer

shared by kuni katsuya on 09 Aug 12 - No Cached
  • 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

Dependency injection discourages object-oriented programming? @ Blog of Adam Warski - 0 views

java javaee6 CDI CdiDependencyInjection OO Object-Oriented procedural DI DependencyInjection

shared by kuni katsuya on 12 Dec 12 - No Cached
  • Dependency injection discourages object-oriented programming?
  • if you’re using DI, and you have an X entity, do you have an XService or XManager with lots of method where X is the first argument?
    • kuni katsuya
      kuni katsuya on 12 Dec 12
       
      evidence of the anti-pattern of procedural design in a java ee6 cdi application
  • previous way is more procedural
    • kuni katsuya
      kuni katsuya on 12 Dec 12
       
      ie. ProductService.ship(Product,Customer)
  • ...12 more annotations...
  • service/manager is a set of procedures you can run, where the execution takes a product and a customer as arguments
  • better
  • OO approach
  • not saying that achieving the above is not possible with a DI framework
  • only that DI
  • encourages the ProductService approach
    • kuni katsuya
      kuni katsuya on 12 Dec 12
       
      well, dependency injection, but moreover, the soa approach to service design tends to force otherwise intelligent software engineers into doing procedural design the services just end up being bags of method calls that implement any type of behavior, with the domain objects or entity beans being reduced to mere data structures with little responsibility or behavior beyond persistence. (which, in this anti-pattern, is typically mostly provided by the repository or dao class! ie. domain object crud)
  • it’s just easier
    • kuni katsuya
      kuni katsuya on 12 Dec 12
       
      ... if you just blindly follow the anti-pattern, of course  ;)
  • many benefits
    • kuni katsuya
      kuni katsuya on 12 Dec 12
       
      with the procedural approach, you also cannot implement polymorphic behavior, for instance
  • builder
  • fluent interface
  • it’s not for small projects
    • kuni katsuya
      kuni katsuya on 12 Dec 12
       
      fuckwhat? small or big matters not. if di is applied poorly, regardless of project size, it's an anti-pattern! disregard these comments!
  • problems with DI frameworks:

  • The 4 Most Important Skills for a Software Developer
  • Skill 1: Solving Problems
  • It is amazing how bad most developers are at solving problems.
  • ...17 more annotations...
  • problem solving is the base skill of software development.
  • Skill 2: Teaching Yourself
  • There is probably no more important skill in life than learning to learn.
  • especially important in software development, because no field I know of changes more rapidly than software development.
  • need the ability to quickly acquire the knowledge you need for the task at hand.
  • learn how to teach yourself
  • Skill 3: Naming
  • Software development is all about describing the metaphysical
  • Every time you are writing code you are naming things
  • can accurately predict a developer’s skill level by looking at how they have named methods, variables and classes in code they have written
  • A developer who lacks the ability to give good names to concepts and data in their code is like a mute translator
  • focus on giving good names to things
  • most visible thing about your code
  • if I read it and can understand it, I am going to assume you know what you are doing.
  • Skill 4: Dealing with People
  • humans are not logical creatures
  • we are emotional ones

  • one direction must be defined as the owner and the other must use the mappedBy attribute to define its mapping
  • you will end up getting duplicate rows
  • If the mappedBy is not used, then the persistence provider will assume there are two independent relationships
  • As with all bi-directional relationships it is your object model's and application's responsibility to maintain the relationship in both direction
  • Mapping a Join Table with Additional Columns
  • solution is to create a class that models the join table
  • requires a composite primary key
  • To make your life simpler, I would recommend adding a generated Id attribute to the association class
