    "HTTP application to use Fiddler? You can either directly configure the WinHTTP application to point to Fiddler, in code, or you can use the following command at the command prompt to tell WinHTTP to use Fiddler: On XP or below: proxycfg -p http=127.0.0.1:8888;https=127.0.0.1:8888 ...or this one to force WinHTTP to use WinINET's proxy settings: proxycfg -u On Vista or above, use an Elevated (admin) command prompt: netsh winhttp set proxy 127.0.0.1:8888 Note: On Windows 7 and earlier, netsh is bitness specific, so you may want to run the above command twice: first using the 32bit NETSH and then using the 64bit NETSH. This blog has more information. This issue was fixed in Windows 8; you can call either NetSh just once to set the proxy for both 32bit and 64bit WinHTTP hosts. Capture traffic from a different account, like ASP.NET on IIS or from a Windows Service? Trying to capture SOAP calls coming from ASP.NET or some background service process?  By default, Fiddler registers as the proxy only for the current user account (ASP.NET runs in a different user account). To get a background process (like the ASP.NET or IIS process) to use Fiddler, you must configure that process to use Fiddler. Typically, this is done by editing web.config or machine.config for the ASP.NET installation, or the configuration for the code running within the Windows Service. Please see http://msdn.microsoft.com/en-us/magazine/cc300743.aspx#S4 or the section on .NET or WinHTTP, depending on which network stack the service is using. Configure Windows Phone 7 to use Fiddler? Please see http://blogs.msdn.com/b/fiddler/archive/2011/01/09/debugging-windows-phone-7-device-traffic-with-fiddler.aspx for actual device hardware, or http://blogs.msdn.com/b/fiddler/archive/2010/10/15/fiddler-and-the-windows-phone-emulator.aspx for the emulator.

  • Set break points in my Java code Start up the Java application server with the appropriate debug JVM properties set (e.g. -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n) From Eclipse, I attach a remote debugger to the app server on the default port 8000. The Java Debugger will open up when a break point is hit. Set breakpoints in my Flex application (or one of its modules). From Eclipse (with Flash Builder) I launch a debug configuration for my Flex app. The Flex Debugger will open up when a break point is hit. At this point I have two debuggers open and everything work great. Two other things I do: a) extend the transaction system timeout, so it doesn't get trigger while I am sitting there think for a few minutes b) use Charles Proxy (in reverse proxy mode) inbetween the client and server to watch the AMF traffic and view payloads, etc.

cdi constructor invocation @PostConstruct

shared by kuni katsuya on 12 Jul 12 - No Cached
  • Why is the constructor invoked twice when a normal scoped bean is created?
  • What you see is the instantiation of two objects: one is the actual bean instance, the other one is the proxy. Both likely invoke the default constructor.
  • That's why it's generally considered a bad idea to do initialization in class construction code. Instead, when using managed beans (objects managed by the EE container) to perform initialisation in a @PostConstruct or @Inject annotated method.

  • 5.3. Java Classes and Corresponding Templates
  • ...13 more annotations...
  • summary of templates used by the generator depending on the kind of Java class it encounters:
  • these templates are bundled in the granite-generator.jar archive, in the org.granite.generator.template package and accessible as resources via the class loader
  • class: protocol is used because all standard templates are available in the classpath
  • Alternatively, you may use the file: protocol to load your template from the filesystem. These templates can be specified either by using absolute paths (eg. file:/absolute/path/to/mytemplate.gsp) or paths relative to your current Eclipse project root directory (eg. path/to/mytemplate.gsp).
  • ActionScript 3 generator is able to write AS3 typed client proxies for exposed remote services
  • Compared to the usual Flex RemoteObject, this can greatly help development by bringing
  • auto-completion
  • improved type-safety
  • in Flex when using remote services.
  • replicate validation annotations in order to use the Flex side validation framework
  •  Known Limitations
  • Gas3 does not support inner classes
  • must declare your classes in separated source files if you want them to be correctly handled by the generator

How To Deal With Interfaces In Java EE 6 (or no more Impl) : Adam Bien's Weblog - 0 views

shared by kuni katsuya on 04 Aug 12 - No Cached
  • How To Deal With Interfaces In Java EE 6 (or no more Impl)
  • In Java EE 6 interfaces became absolutely optional. Neither in EJB 3.1, nor CDI / JSR-330 you need interfaces. You can inject classes directly. They will be still proxied, so all aspects like persistence, transactions, interceptors, decorators are still available. So you are no more forced to implement interfaces by the container
  • used for: Strategy Pattern: there are already several implementations of an algorithm or concept Layering: there is a clear need to hide e.g. an ugly implementation of a legacy framework API (not very common): you have to expose a API, which gets implemented by SPI (e.g. JDBC)
  • ...4 more annotations...
  • If you introduce interfaces intentionally - and not as a general rule, you will considerably reduce the number of files. Your code becomes easier to understand and so maintain
  • Even for decoupling purposes, interfaces are no more needed
  • "Contract First", "Coding To Interfaces" or "Decoupling"
  • is not a reason to introduce an interface for everything

  • ...70 more annotations...
  • @MappedSuperclass
  • Important things on ID/UID
  • entity lives in three layers:
  • Flex client
  • JPA persistence context
  • database
  • When updating existing entities coming from the database
  • id is defined and is maintained in the three layers during the different serialization/persistence operations
  • when a new entity is being created in any of the two upper layers (Flex/JPA)
  • new entity has no id until it has been persisted to the database
  • most common solution is to
  • have a second persisted id, the uid
  • which is created by the client and persisted along with the entity
  • recommended approach to avoid any kind of subtle problems is to have a real uid property which will be persisted in the database but is not a primary key for efficiency concerns
  • You can now ask Tide to
  • limit the object graph before sending it
  • Flex with the following API :
  • EntityGraphUnintializer
  • uninitializeEntityGraph
  • Person object will be uninitialized
  • uperson contains
  • only the minimum of data
  • to correctly merge your changes in the server persistence context
  • Tide uses the
  • client data tracking
  • to determine which parts of the graph need to be sent
  • Calling the EntityGraphUninitializer manually is a bit tedious and ugly, so there is a cleaner possibility when you are using generated typesafe service proxies
  • annotate your service method arguments with @org.granite.tide.data.Lazy :
  • @Lazy
  • take care that you have added the [Lazy] annotation to your Flex metadata compilation configuration
  • in the Flex application, register the UninitializeArgumentPreprocessor component in Tide as follows :
  • [UninitializeArgumentPreprocessor]
  • all calls to PersonService.save() will
  • automatically use a properly uninitialized version
  • of the person argument.
  • 15.4. Dirty Checking and Conflict Handling
  • simplify the handling of data between Flex and Java EE
  • Chapter 15. Data Management
  • Tide maintains a client-side cache of entity instances and ensures that every instance is unique in the Flex client context
  •  uid().hashCode();
  • Tide currently only supports Integer or Long version fields, not timestamps and that the field must be nullable
  • in a multi-tier environment (@Version annotation)
  • highly recommended to use
  • JPA optimistic locking
  • highly recommended to add a
  • persistent uid field
  • AbstractEntity
  • in general this identifier will be
  • initialized from Flex
  • @Column(name="ENTITY_UID", unique=true, nullable=false, updatable=false, length=36)     private String uid;
  • @Version     private Integer version;
  • uid().equals(((AbstractEntity)o).uid())
  • consistent identifier through all application layers

  • 15.4. Dirty Checking and Conflict Handling
  • 15.4. Dirty Checking and Conflict Handling
  • 15.4. Dirty Checking and Conflict Handling
  • Dirty Checking and Conflict Handling
  • entity instance can be in two states :
  • Stable
  • Dirty
  • property meta_dirty is
  • bindable
  • could be used
  • to enable/disable a Save button
  • correct way of knowing if any object has been changed in the context, is to use the property meta_dirty of the Tide context
  • tideContext.meta_dirty
  • reliable when using optimistic locking
  • check that its @Version field has been incremented
