While client libraries for Facebook Platform developers exist in many programming languages, you can scratch official support for Java off the list. Facebook announced today that as of next Tuesday, it will no longer be supporting its Java client library, instead relying on community-created libraries.  As Facebook’s James Leszczenski writes,

We encourage all developers who are interested in continuing to develop in Java to consider some of the open source alternative client libraries listed on the Wiki here. While the official Java library should have no immediate problems with continued use, we nevertheless recommend that you use a client library that is kept up to date, in order to best take advantage of any new functionality that is added in the future.

While the number of apps written in Java is small, this is likely to be an inconvenience to those that have chosen to build using Facebook’s official libraries.
