java code analysis best practices

shared by kuni katsuya on 09 May 12 - No Cached
  • Best Practices
  • start with some of the obvious rulesets - just run unusedcode and fix any unused locals and fields. Then, run basic and fix all the empty if statements and such-like. Then peruse the design and controversial rulesets and use the ones you like via a custom ruleset
  • Using PMD within your IDE is much more enjoyable than flipping back and forth between an HTML report and your IDE

shared by kuni katsuya on 12 Sep 12 - No Cached
  • 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.

  • 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.

      generally speaking, there can be a few independent but overlapping mechanism that will control who is allowed to do what with content: 1. any subject's access to the content itself can be controlled via authorization rules (ie. required vs granted permissions) enforced via system-wide resource-based access control 2. content licensors (~content owners) can restrict the usage of their content by: * whom - ie. content licensee (legally/commercially represented by an organization) * how - eg. reuse as unmodified, create derivatives, composite, redistribute, etc * where - ie. distribution channels their content can be used (eg. only on hotel's vbrochure site, but not in any ids/gds channels) * when - temporal restrictions may limit scope of content license grant by: start, end, duration, season, etc 3. content licensees can further filter or funnel content available to them (resulting from a combination of license granted to them and access control) based on their own criteria (eg. generate a templated hotel presentation only if: at least 1 textual description, 5 photos and 1 video for a hotel is available with a license to combine them (composite content)

      if ecm/vfml is to manage content licensing as a third party between organizations (content licensors & licensees) shouldn't ecm *know* if the user('s organization) has rights to use the content in question? is this question posed to the user (with required explicit acknowledgement) purely to absolve vfml from liability issues that may result from licensing disagreements?

      this being the user's (organization's) 'version'or 'view'of the hotel, since this user normally wouldn't/shouldn't be granted permissions to replace content for a hotel on a different organization's 'view'or 'version' of the same hotel

    • kuni katsuya

      this implies that *at least* one version of such (temporarily) replaceable content needs to be managed/maintaned to allow reverting what if, deliberately, ignorantly or maliciously, a user replaces the same piece of--textual or any type, really--content for this hotel n times? will all n versions be required to be managed as an undo history? the user's ''original content'' might have been version 1, but equally might have been 1 mean: - previous version of the content, regardless of which user - initial version of that content attached to the hotel regardless of which user created/updated it and ignoring which organization owns it?, or, -
