The EJB Specification, Concurrency, and Batch Processing
March 1, 2009 by Frank Salinas · 1 Comment
The EJB specification does not leave much room for implementing concurrent processing within the EJB container. This poses a problem to developers who need to implement solutions for processing long running batch processes as part of the business logic of an application. The EJB specification states the following:
The enterprise bean must not attempt to manage threads. The enterprise bean must not attempt to start, stop, suspend, or resume a thread, or to change a thread’s priority or name. The enterprise bean must not attempt to manage thread groups.
These functions are reserved for the EJB container. Allowing the enterprise bean to manage threads would decrease the container’s ability to properly manage the runtime environment.
