javax.ejb
Interface SessionContext

All Superinterfaces:

EJBContext

public interface SessionContext

extends EJBContext

The SessionContext interface provides access to the runtime session context that the container provides for a session enterprise Bean instance. The container passes the SessionContext interface to an instance after the instance has been created. The session context remains associated with the instance for the lifetime of the instance. SessionContext接口提供了对容器为会话企业Bean实例提供的运行时会话上下文 的访问。容器在实例创建后将SessionContext接口传递给实例。会话上下文 在实例的生命周期内保持与实例关联。

Method Summary
EJBLocalObject	getEJBLocalObject()           Obtain a reference to the EJB local object that is associated with the instance. 获取与实例关联的EJB本地对象引用。
EJBObject	getEJBObject()           Obtain a reference to the EJB object that is currently associated with the instance. 获取当前与实例关联的EJB对象引用。
MessageContext	getMessageContext()           Obtain a reference to the JAX-RPC MessageContext. 获取JAX-RPC MessageContext引用。

Method Detail

getEJBLocalObject

public EJBLocalObject getEJBLocalObject()
                                 throws IllegalStateException

Obtain a reference to the EJB local object that is associated with the instance. 获取与实例关联的EJB本地对象引用。

An instance of a session enterprise Bean can call this method at anytime between the ejbCreate() and ejbRemove() methods, including from within the ejbCreate() and ejbRemove() methods. 会话企业Bean的实例的ejbCreate()和ejbRemove()之间的方法（包括从ejbRemove() 和ejbRemove()方法）可以随时调用该方法。

An instance can use this method, for example, when it wants to pass a reference to itself in a method argument or result. 实例可以使用该方法，比如，以方法参数或结果形式传递自身引用。

Returns:

The EJB local object currently associated with the instance. 当前与实例关联的EJB本地对象。

Throws:

IllegalStateException - Thrown if the instance invokes this method while the instance is in a state that does not allow the instance to invoke this method, or if the instance does not have a local interface. 如果实例调用改方法而实例所在的状态不允许其调用该方法或者实例没有本地接口时抛出。

getEJBObject

public EJBObject getEJBObject()
                       throws IllegalStateException

Obtain a reference to the EJB object that is currently associated with the instance. 获取当前与实例关联的EJB对象引用。

An instance of a session enterprise Bean can call this method at anytime between the ejbCreate() and ejbRemove() methods, including from within the ejbCreate() and ejbRemove() methods. 会话企业Bean的实例的ejbCreate()和ejbRemove()之间的方法（包括从ejbRemove() 和ejbRemove()方法）可以随时调用该方法。

An instance can use this method, for example, when it wants to pass a reference to itself in a method argument or result. 实例可以使用该方法，比如，以方法参数或结果形式传递自身引用。

Returns:

The EJB object currently associated with the instance. 当前与实例关联的EJB对象。

Throws:

IllegalStateException - Thrown if the instance invokes this method while the instance is in a state that does not allow the instance to invoke this method, or if the instance does not have a remote interface. 如果实例调用改方法而实例所在的状态不允许其调用该方法或者实例没有远程接口时抛出。

getMessageContext

public MessageContext getMessageContext()
                                 throws IllegalStateException

Obtain a reference to the JAX-RPC MessageContext. 获取JAX-RPC MessageContext引用。

An instance of a stateless session bean can call this method from any business method invoked through its web service endpoint interface. 无状态会话bean可以从通过web service终点接口调用的业务方法中调用该方法。

Returns:

The MessageContext for this web service invocation. 用于web service调用的MessageContext。

Throws:

IllegalStateException - Thrown if this method is invoked while the instance is in a state that does not allow access to this method. 如果实例调用改方法而实例所在的状态不允许其 访问该方法时抛出。
