javaee6 lean service architecture

shared by kuni katsuya on 30 Jul 12 - No Cached
  • 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

eclipse preferences configuration

shared by kuni katsuya on 17 Jul 12 - Cached
  • Where are Eclipse preferences stored?
  • Preferences are stored in various places (this applies to Eclipse 3.1)
  • for each installation (but this may vary for multi-user installations), in files stored in <eclipse_home>/eclipse/configuration/.settings/
  • ...18 more annotations...
  • for each workspace, in files stored in <workspace>/.metadata/.plugin/org.eclipse.core.runtime/.settings
  • for each project --for project-level settings -- in files stored in a .settings sub-directory of your project folder
  • Is there an UML editor for Eclipse? An Eclipse Modelling project-based UML editor can be installed from the Eclipse update site "Modelling > UML2 Tools SDK". See Creating UML 2 diagrams with Eclipse UML2 Tools - Tutorial for an introduction.
  • How do I debug Eclipse? How can I see what plug-ins are being started? Why aren't the plug-ins I installed showing up in the UI? How do I start the OSGi console?
  • Debugging OSGi Bundle Loading Issues There are a few flags you can pass to Eclipse on the commandline or in your eclipse.ini file that might help: -consolelog - log everything in workspace/.metadata/.log to the console where you launched Eclipse as well -debug - more verbose console output -console - start the Equinox OSGi console to interact with OSGi directly -noexit - when Eclipse closes, keep the OSGi console running until you type 'exit' or hit CTRL-C so you can keep debugging See Where Is My Bundle? for an overview of how to use the OSGi console for diagnosing problems.
  • Debugging Eclipse Using Eclipse You can also debug an Eclipse instance from another instance through remote debugging: Start the instance to be debugged with "-vmargs -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,address=8000". You should see a message like "Listening for transport dt_socket at address: 8000" Open Run → Debug Configurations... and create a Remote Java Application configuration with connection type "Socket Attach" and connecting to the client at port 8000. Set the project to a bundle project with the right dependencies for the bundles that you are trying to debug. Launch the configuration. The JDWP agent supports other useful arguments, like "suspend=n" so that the process does not suspend. For more details, see Oracle's Java Debug Wire Protocol (JDWP) connection docs.
  • I just installed Eclipse on my 64-bit system, but it does not start. What is the problem? Make sure that you have downloaded the 64-bit version of Eclipse (it should have x86_64 somewhere in its name) and have installed a 64-bit JVM. Likewise, if you run a 32-bit JVM, then you should use the 32-bit version of Eclipse.
  • When I start Eclipse it says "Workspace in use or cannot be created, choose a different one.", what should I do? There are a couple of things you can try. Delete the workspace/.metadata/.lock file. Check your running processes to make sure there aren't any remaining Java or Eclipse processes running. When in doubt, restart your computer. :) Try starting Eclipse on a different workspace (from the workspace selection dialog, or by using a command line argument like -data /home/user/tmp-workspace), then switch back to your original workspace.
  • How do I uninstall a plug-in? You can view your list of installed software by checking your installation details from about dialog. Help > About > Installation Details
  • I'm having memory, heap, or permgen problems, what can I do? FAQ How do I increase the heap size available to Eclipse? FAQ How do I increase the permgen size available to Eclipse?
  • Eclipse seems to be hanging on startup. How can I find out why? If none of the solutions outlined in this section reveal the problem, then you can try debugging an Eclipse instance as a debug target from another Eclipse instance. This is surprisingly easy: Start Eclipse in a "new" blank workspace (e.g., C:\TEMP\WS, or /tmp) Create a new Debug configuration: Run -> Debug Configurations; then click on "Eclipse Applications" and select the New Launch Configuration. If you believe it's something about a particular workspace, then set the workspace to your normal workspace. If you believe the hang is caused by a particular plugin, disable the plugin and verify. Launch and then see. Using this approach, you can break with the debugger to see where hangs are occurring. You can also change the selection of plugins that the instance is launched with.
  • I was working on a project and doing something or other does not work. Where should I start? Try refreshing your projects. Try cleaning your your projects using the menu item Project/Clean to trigger a rebuild. Try closing/reopening your projects. Try restarting Eclipse.
  • 4.2 Where are Eclipse's log files located?
  • Where are Eclipse's log files located? <workspace>/.metadata/.log You can view this workspace log as a view if you have PDE installed on your computer (which you would if you have downloaded the Eclipse SDK). You can open that view via Window -> Show View -> Other -> PDE Runtime -> Error Log. <eclipse install>/configuration/<sometimestamp>.log <eclipse install>/configuration/org.eclipse.update/install.log
  • Where are Eclipse preferences stored?
  • Where are Eclipse preferences stored?
  • Where are Eclipse preferences stored?
  • Where are update site bookmarks stored? It is within an XML file called <user_home>/.eclipse/org.eclipse.platform_3.1.2/configuration/org.eclipse.update/bookmarks.xml. Your Eclipse version may vary.

Application Security With Apache Shiro - 0 views

security ApacheShiro

shared by kuni katsuya on 08 Aug 12 - No Cached
  • 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
  • ...12 more annotations...
  • Subject
  • 'Subject' can mean a human being, but also a 3rd party process, daemon account, or anything similar. It simply means 'the thing that is currently interacting with the software'
  • Subject currentUser = SecurityUtils.getSubject();
  • SecurityManager
  • SecurityManager manages security operations for all users
  • Realms
  • Realm acts as the ‘bridge’ or ‘connector’ between Shiro and your application’s security data. That is, when it comes time to actually interact with security-related data like user accounts to perform authentication (login) and authorization (access control), Shiro looks up many of these things from one or more Realms configured for an application.
  • Realm is essentially a security-specific DAO
  • Shiro provides out-of-the-box Realms to connect to a number of security data sources (aka directories) such as LDAP, relational databases (JDBC), text configuration sources like INI and properties files, and more
  • Authorization
  • A permission is a raw statement of functionality, for example ‘open a door’, ‘create a blog entry’, ‘delete the ‘jsmith’ user’, etc. By having permissions reflect your application’s raw functionality, you only need to change permission checks when you change your application’s functionality. In turn, you can assign permissions to roles or to users as necessary at runtime.
  • “Run As” support for assuming the identity of another Subject
