javax.ejb .EJBContext

EJBContext
public interface EJBContext (Code)
	The EJBContext interface provides an instance with access to the container-provided runtime context of an enterprise Bean instance. This interface is extended by the SessionContext, EntityContext, and MessageDrivenContext interfaces to provide additional methods specific to the enterprise interface Bean type.

Method Summary
Identity	getCallerIdentity() Obtain the java.security.Identity of the caller. This method is deprecated in EJB 1.1.
Principal	getCallerPrincipal() Obtain the java.security.Principal that identifies the caller. The Principal object that identifies the caller.
EJBHome	getEJBHome() Obtain the enterprise bean's remote home interface.
EJBLocalHome	getEJBLocalHome() Obtain the enterprise bean's local home interface.
Properties	getEnvironment() Obtain the enterprise bean's environment properties. Note: If the enterprise bean has no environment properties this method returns an empty java.util.Properties object.
boolean	getRollbackOnly() Test if the transaction has been marked for rollback only.
TimerService	getTimerService() Get access to the EJB Timer Service. exception: IllegalStateException - The Container throws the exceptionif the instance is not allowed to use this method (e.g.
UserTransaction	getUserTransaction() Obtain the transaction demarcation interface. Only enterprise beans with bean-managed transactions are allowed to to use the UserTransaction interface.
boolean	isCallerInRole(Identity role) Test if the caller has a given role. This method is deprecated in EJB 1.1.
boolean	isCallerInRole(String roleName) Test if the caller has a given security role. Parameters: roleName - The name of the security role.
Object	lookup(String name) Lookup a resource within the component's private naming context.
void	setRollbackOnly() Mark the current transaction for rollback.

Method Detail

getCallerIdentity
Identity getCallerIdentity()(Code)
	Obtain the java.security.Identity of the caller. This method is deprecated in EJB 1.1. The Container is allowed to return alway null from this method. The enterprise bean should use the getCallerPrincipal method instead. The Identity object that identifies the caller.

getCallerPrincipal
Principal getCallerPrincipal()(Code)
	Obtain the java.security.Principal that identifies the caller. The Principal object that identifies the caller. Thismethod never returns null. exception: IllegalStateException - The Container throws the exceptionif the instance is not allowed to call this method.

getEJBHome
EJBHome getEJBHome()(Code)
	Obtain the enterprise bean's remote home interface. The enterprise bean's remote home interface. exception: java.lang.IllegalStateException - if the enterprise bean does not have a remote home interface.

getEJBLocalHome
EJBLocalHome getEJBLocalHome()(Code)
	Obtain the enterprise bean's local home interface. The enterprise bean's local home interface. exception: java.lang.IllegalStateException - if the enterprise bean does not have a local home interface.

getEnvironment
Properties getEnvironment()(Code)
	Obtain the enterprise bean's environment properties. Note: If the enterprise bean has no environment properties this method returns an empty java.util.Properties object. This method never returns null. The environment properties for the enterprise bean.

getRollbackOnly
boolean getRollbackOnly() throws IllegalStateException(Code)
	Test if the transaction has been marked for rollback only. An enterprise bean instance can use this operation, for example, to test after an exception has been caught, whether it is fruitless to continue computation on behalf of the current transaction. Only enterprise beans with container-managed transactions are allowed to use this method. True if the current transaction is marked for rollback, falseotherwise. exception: IllegalStateException - The Container throws the exceptionif the instance is not allowed to use this method (i.e. theinstance is of a bean with bean-managed transactions).

getTimerService
TimerService getTimerService() throws IllegalStateException(Code)
	Get access to the EJB Timer Service. exception: IllegalStateException - The Container throws the exceptionif the instance is not allowed to use this method (e.g. if the beanis a stateful session bean)

getUserTransaction
UserTransaction getUserTransaction() throws IllegalStateException(Code)
	Obtain the transaction demarcation interface. Only enterprise beans with bean-managed transactions are allowed to to use the UserTransaction interface. As entity beans must always use container-managed transactions, only session beans or message-driven beans with bean-managed transactions are allowed to invoke this method. The UserTransaction interface that the enterprise beaninstance can use for transaction demarcation. exception: IllegalStateException - The Container throws the exceptionif the instance is not allowed to use the UserTransaction interface(i.e. the instance is of a bean with container-managed transactions).

isCallerInRole
boolean isCallerInRole(Identity role)(Code)
	Test if the caller has a given role. This method is deprecated in EJB 1.1. The enterprise bean should use the isCallerInRole(String roleName) method instead. Parameters: role - The java.security.Identity of the role to be tested. True if the caller has the specified role.

isCallerInRole
boolean isCallerInRole(String roleName)(Code)
	Test if the caller has a given security role. Parameters: roleName - The name of the security role. The role must be one ofthe security roles that is defined in the deployment descriptor. True if the caller has the specified role. exception: IllegalStateException - The Container throws the exceptionif the instance is not allowed to call this method.

lookup
Object lookup(String name)(Code)
	Lookup a resource within the component's private naming context. Parameters: name - Name of the entry (relative to java:comp/env). exception: IllegalArgumentException - The Container throws the exceptionif the given name does not match an entry within the component'senvironment.

setRollbackOnly
void setRollbackOnly() throws IllegalStateException(Code)
	Mark the current transaction for rollback. The transaction will become permanently marked for rollback. A transaction marked for rollback can never commit. Only enterprise beans with container-managed transactions are allowed to use this method. exception: IllegalStateException - The Container throws the exceptionif the instance is not allowed to use this method (i.e. theinstance is of a bean with bean-managed transactions).
