  • Implications of choosing WAR vs EAR deployment
  • Development and runtime configuration including:
    • Seam package structures and configuration file locations
    • Configuring database connection details
    • Configuring classpaths and included jars
  • Application generation including:
    • Generation of an application scaffold
    • Generation of Entities from an existing DB
    • Generation of views and actions from Entities
  • Extending an existing, possibly generated application including:
    • Adding new entities
    • Adding new components and actions
    • Importing and using existing components and entities
  • Application deployment issues, tools, and options including:
    • Hot deployment via JBoss Tools
    • Hot deployment via build.xml integration
    • Source path-based stereotypes (hot deployed or not)
  • Debugging a seam application

Work with Seam Contexts

  • XML configuration of component lifecycles and contexts
  • Conversations:
    • Understand temporary versus long-running
    • Understand conversation promotion
  • Conversation demarcation/propagation:
    • Using @Begin, @End
    • Using pages.xml
    • From inside views
  • Relation between conversations, transactions, and persistence context (flushmode)
  • Understand concurrent access in Seam
  • Selecting an appropriate context for work being done
  • Context order for resolution of injected components/context variables
  • Update use case to handle wizard-typed view flow and code-backed bean conversational Manager
  • Choosing start/end/propagate lifecycle for a long-running conversation
  • Configure the persistence context to be supported by a long-running conversation; specifically know when to flush the persistence context
  • Improve readability with natural conversation Ids
  • Manage conversation-related errors

Work with Seam POJO/Java EE components

  • Differences between EJB3-based components and POJO-based components
  • Component definition:
    • @Name
    • XML Configuration
    • fined grained configuration files
  • Seam application framework:
    • Understand and create Seam Home and Query objects
  • Component lifecycle
  • Component/contexts interaction:
  • @In, @Out
    • Understand disinjection
    • Understand pass by value
    • Understand interception including adding seam interception for EJB3 components
    • Understand implication of use of proxies
    • Understand implication of recursive/inner call
    • XML Config
  • @Factory
  • @Unwrap
  • Setting component/context variable in particular context using Seam APIs

  • Built-in components/features:
    • i18n
    • @Log
    • Authenticator component
    • Asynchronous call
  • Know in detail the differences between a persistence context annotated with @In and @PersistenceContext (in case of use in EE)
  • Relation between conversations, transactions and persistence context flushmode
  • XML Configuration related to conversation
  • Security-related features, including (list not exhaustive):
    • Authentication
    • Restriction
    • Security events
    • Bind authentication methods
    • Access and manage identity information through API
  • Debugging a Seam application
  • Detecting and handling performance issues

  • Update existing Home and Query, including adding a search criteria
  • Choose between @Out, @Factory, @Unwrap to place component(s)/context variable(s) in desired context
  • Choose between serial or pooling approach to handle component call concurrency (typically from Ajax requests)
  • Tuning performance avoiding interceptor @ByPassInterceptor
  • When to use @DataModel and @DataModelSelection

Work with Seam Web/JSF components

  • Understand and use pages.xml including all navigation features
  • Postback lifecycle
