Interface EJBContext

All Known Subinterfaces:
MessageDrivenContext, SessionContext
public interface EJBContext
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.

Since:
EJB 1.0

  • Method Details

    • getEJBHome

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

    • getEJBLocalHome

      EJBLocalHome getEJBLocalHome() throws IllegalStateException
      Obtain the enterprise bean's local home interface.
      Returns:
      The enterprise bean's local home interface.
      Throws:
      IllegalStateException - if the enterprise bean does not have a local home interface.
      Since:
      EJB 2.0

    • getEnvironment

      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. This method never returns null.

      Returns:
      The environment properties for the enterprise bean.

    • getCallerIdentity

      Identity getCallerIdentity()
      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 always null from this method. The enterprise bean should use the getCallerPrincipal method instead.
      Returns:
      The Identity object that identifies the caller.

    • getCallerPrincipal

      Principal getCallerPrincipal() throws IllegalStateException
      Obtain the java.security.Principal that identifies the caller.
      Returns:
      The Principal object that identifies the caller. This method never returns null.
      Throws:
      IllegalStateException - The Container throws the exception if the instance is not allowed to call this method.
      Since:
      EJB 1.1

    • isCallerInRole

      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. The enterprise bean should use the isCallerInRole(String roleName) method instead.

      Parameters:
      role - The java.security.Identity of the role to be tested.
      Returns:
      True if the caller has the specified role.

    • isCallerInRole

      boolean isCallerInRole(String roleName) throws IllegalStateException
      Test if the caller has a given security role.
      Parameters:
      roleName - The name of the security role. The role must be one of the security roles that is defined in the deployment descriptor.
      Returns:
      True if the caller has the specified role.
      Throws:
      IllegalStateException - The Container throws the exception if the instance is not allowed to call this method.
      Since:
      EJB 1.1

    • getUserTransaction

      UserTransaction getUserTransaction() throws IllegalStateException
      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.
      Returns:
      The UserTransaction interface that the enterprise bean instance can use for transaction demarcation.
      Throws:
      IllegalStateException - The Container throws the exception if the instance is not allowed to use the UserTransaction interface (i.e. the instance is of a bean with container-managed transactions).

    • setRollbackOnly

      void setRollbackOnly() throws IllegalStateException
      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:
      IllegalStateException - The Container throws the exception if the instance is not allowed to use this method (i.e. the instance is of a bean with bean-managed transactions).

    • getRollbackOnly

      boolean getRollbackOnly() throws IllegalStateException
      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.
      Returns:
      True if the current transaction is marked for rollback, false otherwise.
      Throws:
      IllegalStateException - The Container throws the exception if the instance is not allowed to use this method (i.e. the instance is of a bean with bean-managed transactions).

    • getTimerService

      TimerService getTimerService() throws IllegalStateException
      Get access to the EJB Timer Service.
      Throws:
      IllegalStateException - The Container throws the exception if the instance is not allowed to use this method (e.g. if the bean is a stateful session bean)
      Since:
      EJB 2.1

    • lookup

      Object lookup(String name) throws IllegalArgumentException
      Lookup a resource within the java: namespace. Names referring to entries within the private component namespace can be passed as unqualified strings. In that case the lookup will be relative to "java:comp/env/". For example, assuming an enterprise bean defines an ejb-local-ref with ejb-ref-name "ejb/BarRef" the following two calls to EJBContext.lookup are equivalent : ejbContext.lookup("ejb/BarRef"); ejbContext.lookup("java:comp/env/ejb/BarRef");
      Parameters:
      name - Name of the entry
      Throws:
      IllegalArgumentException - The Container throws the exception if the given name does not match an entry within the component's environment.
      Since:
      EJB 3.0

    • getContextData

      Map<String,Object> getContextData()
      The getContextData method enables a business method, lifecycle callback method, or timeout method to retrieve any interceptor/webservices context associated with its invocation.
      Returns:
      the context data that interceptor context associated with this invocation. If there is no context data, an empty Map<String,Object> object will be returned.
      Since:
      EJB 3.1
