• Key Concepts: 
  A reentrant enterprise bean is a type of Enterprise JavaBean (EJB) that can be called multiple times by the same client without having to be re-instantiated. This allows for improved performance and scalability, as the bean can be reused without having to be recreated each time. 
  
  How to use it: 
  Reentrant enterprise beans are used in the SAP BC-JAS-EJB Container EJB. To use a reentrant enterprise bean, you must first create an instance of the bean and then call its methods. The bean will then execute the requested operations and return the results. 
  
  Tips & Tricks: 
  When using reentrant enterprise beans, it is important to ensure that the bean is thread-safe. This means that all operations performed by the bean must be thread-safe, as multiple threads may be accessing the same instance of the bean at any given time.
