Method Detail

setSessionContext

public void setSessionContext(javax.ejb.SessionContext context)

Specified by:

setSessionContext in interface javax.ejb.SessionBean

getSessionContext

public javax.ejb.SessionContext getSessionContext()

Description copied from class: EJBComponent

Returns the context passed to the EJB's setSessionContext method.

Specified by:

getSessionContext in class EJBComponent

Returns:

session context.

ejbActivate

public void ejbActivate()

Specified by:

ejbActivate in interface javax.ejb.SessionBean

ejbPassivate

public void ejbPassivate()

Specified by:

ejbPassivate in interface javax.ejb.SessionBean

ejbRemove

public void ejbRemove()

Specified by:

ejbRemove in interface javax.ejb.SessionBean

ejbCreate

public void ejbCreate()
               throws javax.ejb.CreateException

Throws:

javax.ejb.CreateException

invokeServiceXML

public java.lang.String invokeServiceXML(java.lang.String xml)

Expose services of this EJB via XML. This method unmarshals the XML argument string into an object, finds a method on the EJB to accept that object type as an argument and invokes it. The result returned from the method is marshalled back into XM and returned.

The methods are invoked on the context's local interface if possible (if one exists). If no local interface is found then the remote interface is used instead. Invoking methods via the local/remote interface means that the deployment settings for security and transacts will be honoured.

Parameters:

xml - XML argument to be passed to the service.

Returns:

XML returned from the service.

getCore

public Core getCore()

Description copied from class: Component

Fetch the entry point's instance of the core.

Specified by:

getCore in class Component

Returns:

The core being used by the entry points.

getVersionEffectiveDate

public VersionEffectiveDate getVersionEffectiveDate()

Description copied from class: Component

A default component implemention returning the time now. Components with a critical dependency on selecting the version effective date should override this method.

Specified by:

getVersionEffectiveDate in interface CoreUser

Overrides:

getVersionEffectiveDate in class Component

Returns:

VersionEffectiveDate now.

setConfiguration

public void setConfiguration(Configuration config)

Description copied from class: Component

Default component implementation of the setConfiguration method. This method takes care of saving configrations on the behalf of the entry point.
