Class AbstractSlsbInvokerInterceptor

Constructor Detail

• AbstractSlsbInvokerInterceptor

  public AbstractSlsbInvokerInterceptor()

Method Detail

• setLookupHomeOnStartup

  public void setLookupHomeOnStartup​(boolean lookupHomeOnStartup)

  Set whether to look up the EJB home object on startup. Default is "true".

  Can be turned off to allow for late start of the EJB server. In this case, the EJB home object will be fetched on first access.

  See Also:

  setCacheHome(boolean)

• setCacheHome

  public void setCacheHome​(boolean cacheHome)

  Set whether to cache the EJB home object once it has been located. Default is "true".

  Can be turned off to allow for hot restart of the EJB server. In this case, the EJB home object will be fetched for each invocation.

  See Also:

  setLookupHomeOnStartup(boolean)

• setExposeAccessContext

  public void setExposeAccessContext​(boolean exposeAccessContext)

  Set whether to expose the JNDI environment context for all access to the target EJB, i.e. for all method invocations on the exposed object reference.

  Default is "false", i.e. to only expose the JNDI context for object lookup. Switch this flag to "true" in order to expose the JNDI environment (including the authorization context) for each EJB invocation, as needed by WebLogic for EJBs with authorization requirements.

• afterPropertiesSet

  public void afterPropertiesSet()
                          throws NamingException

  Fetches EJB home on startup, if necessary.

  Specified by:

  afterPropertiesSet in interface InitializingBean

  Overrides:

  afterPropertiesSet in class JndiObjectLocator

  Throws:

  NamingException

  See Also:

  setLookupHomeOnStartup(boolean), refreshHome()

• refreshHome

  protected void refreshHome()
                      throws NamingException

  Refresh the cached home object, if applicable. Also caches the create method on the home object.

  Throws:

  NamingException - if thrown by the JNDI lookup

  See Also:

  JndiObjectLocator.lookup(), getCreateMethod(java.lang.Object)

• getCreateMethod

  protected Method getCreateMethod​(Object home)
                            throws EjbAccessException

  Determine the create method of the given EJB home object.

  Parameters:

  home - the EJB home object

  Returns:

  the create method

  Throws:

  EjbAccessException - if the method couldn't be retrieved

• getHome

  protected Object getHome()
                    throws NamingException

  Return the EJB home object to use. Called for each invocation.

  Default implementation returns the home created on initialization, if any; else, it invokes lookup to get a new proxy for each invocation.

  Can be overridden in subclasses, for example to cache a home object for a given amount of time before recreating it, or to test the home object whether it is still alive.

  Returns:

  the EJB home object to use for an invocation

  Throws:

  NamingException - if proxy creation failed

  See Also:

  JndiObjectLocator.lookup(), getCreateMethod(java.lang.Object)

• isHomeRefreshable

  protected boolean isHomeRefreshable()

  Return whether the cached EJB home object is potentially subject to on-demand refreshing. Default is "false".

• invoke

  public Object invoke​(MethodInvocation invocation)
                throws Throwable

  Prepares the thread context if necessar, and delegates to invokeInContext(org.aopalliance.intercept.MethodInvocation).

  Specified by:

  invoke in interface MethodInterceptor

  Parameters:

  invocation - the method invocation joinpoint

  Returns:

  the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor

  Throws:

  Throwable - if the interceptors or the target object throws an exception

• invokeInContext

  protected abstract Object invokeInContext​(MethodInvocation invocation)
                                     throws Throwable

  Perform the given invocation on the current EJB home, within the thread context being prepared accordingly. Template method to be implemented by subclasses.

  Parameters:

  invocation - the AOP method invocation

  Returns:

  the invocation result, if any

  Throws:

  Throwable - in case of invocation failure

• create

  protected Object create()
                   throws NamingException,
                          InvocationTargetException

  Invokes the create() method on the cached EJB home object.

  Returns:

  a new EJBObject or EJBLocalObject

  Throws:

  NamingException - if thrown by JNDI

  InvocationTargetException - if thrown by the create method
