Description: With the release of JRun 2.2 in mid 1998, Live Software marked the transition of JRun from simple servlet runner to a more comprehensive Java Services Manager. JRun today implements an Enterprise Services Manager (ESM) capable of administering any Java service written to the JRun Services API. In other words, it can be used to deploy a custom Java service as easily as it is used to deploy Servlets. In this article, we provide a discussion of the ESM and what is ahead for JRun.
