Gearman has benefited from many active open source contributors who have each introduced a new project or helped out with an existing one. Some projects are more active than others, each have varying features and performance, but they are all compatible with one another (except for some new protocol additions). If you need help figuring out which option would best suit your needs, get in touch! text/html 2009-08-08T21:47:34+00:00 http://gearman.org/index.php?id=fake_jndi&rev=1249768054&do=diff Back (gearman-jms WiKi) Fake JNDI In most Java Enterprise environments (the main users of JMS), the developers will have a proprietary JNDI implementation that is used for obtaining the Administered Objects (in this case, the ConnectionFactory). Since gearman-jms is an API and not a end-user client application, we make use of a 'fake JNDI' for testing purposes. The Shell application is a console program that allows the user to create a 'named' ConnectionFactory instance.

This allows applications written in Java using JMS to seamlessly interface with a Gearman Job Server. The result is JMS clients can use JMS to request remote work on their behalf, or receive results from a remote function call. JMS workers can use JMS to broadcast to the Job Server what functions they implement, and to receive work requests (and return work results). text/html 2011-03-28T04:57:14+00:00 http://gearman.org/index.php?id=gearman_php_extension&rev=1301288234&do=diff About Gearman PHP Extension The Gearman PHP Extension allows you to write Gearman clients and workers using PHP.
