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 and EntityContext interface to provide additional methods specific to the enterprise Bean type.

version:
$Revision: 57196 $

Method Summary
public Identity	getCallerIdentity() Deprecated. Use Principal getCallerPrincipal() instead. Obtain the java.security.Identity of the caller.
public Principal	getCallerPrincipal() Obtains the java.security.Principal of the caller. The Principal object that identifies the caller.
public EJBHome	getEJBHome() Obtain the enterprise bean's remote home interface.
public EJBLocalHome	getEJBLocalHome() Obtain the enterprise bean's local home interface.
public Properties	getEnvironment() Deprecated. Use the JNDI naming context java:comp/env to access enterprise bean's environment. 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.
public boolean	getRollbackOnly() Test if the transaction has been marked for rollback only.
public TimerService	getTimerService() Get access to the EJB Timer Service. throws: IllegalStateException - The Container throws the exceptionif the instance is not allowed to use this method (e.g.
public UserTransaction	getUserTransaction() Obtain the transaction demarcation interface.
public boolean	isCallerInRole(Identity role) Deprecated. Use boolean isCallerInRole(String roleName) instead. Test if the caller has a given role. This method is deprecated in EJB 1.1.
public boolean	isCallerInRole(String roleName) Tests if the caller has a given role. Parameters: roleName - - The name of the security role.
public Object	lookup(String name) New from EJB 3.0.
public void	setRollbackOnly() Mark the current transaction for rollback.

Method Detail

getCallerIdentity

public Identity getCallerIdentity()(Code)

Deprecated. Use Principal getCallerPrincipal() instead.

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
public Principal getCallerPrincipal()(Code)
	Obtains the java.security.Principal of the caller. The Principal object that identifies the caller. This method never returns null.

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

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

getEnvironment

public Properties getEnvironment()(Code)

Deprecated. Use the JNDI naming context java:comp/env to access enterprise bean's environment.

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
public 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, false otherwise. throws: java.lang.IllegalStateException - - The Container throws the exception if the instanceis not allowed to use this method (i.e. the instance is of a bean with bean-managed transactions).

getTimerService
public TimerService getTimerService() throws IllegalStateException(Code)
	Get access to the EJB Timer Service. throws: 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
public 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 with bean-managed transactions are allowed to invoke this method. The UserTransaction interface that the enterprise bean instance can use for transaction demarcation. throws: java.lang.IllegalStateException - - The Container throws the exception if the instance is notallowed to use the UserTransaction interface (i.e. the instance is of a bean with container-managedtransactions).

isCallerInRole

public boolean isCallerInRole(Identity role)(Code)

Deprecated. Use boolean isCallerInRole(String roleName) instead.

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
public boolean isCallerInRole(String roleName)(Code)
	Tests if the caller has a given role. Parameters: roleName - - The name of the security role. The role must be one of the security roles thatis defined in the deployment descriptor. True if the caller has the specified role.

lookup
public Object lookup(String name)(Code)
	New from EJB 3.0. A JNDI lookup method that doesn't throw exceptions Parameters: name - returns null if JNDI lookup finds nothing

setRollbackOnly
public 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. throws: java.lang.IllegalStateException - - The Container throws the exception if the instance is notallowed to use this method (i.e. the instance is of a bean with bean-managed transactions).
