7 A deployment setup consists of 4 parts:
8
9 * Your application
10 * wotaskd
11 * JavaMonitor (also know as WOMonitor)
12 * A module for your Web server (Apache or IIS)
13
14 wotaskd is a daemon, who is also a WebObjects application, that its main task is to start up instances when hosts are restarted. wotaskd also accepts lifebeats from your application instances, if wotaskd stops receiving lifebeats after a certain amount of time, it will assume that your application is dead.
15
16 JavaMonitor is simply a Web front-end to manage your wotaskd configuration. You can use one copy of JavaMonitor to manage multiple wotaskd daemons running on different nodes.
17
18 The job of the module for your Web server is to talk to wotaskd to find the list of available applications and act as a request proxy between the browser on the client-side and your application.
19
20 Usually, people run wotaskd, JavaMonitor, their applications and the Web server on the same server, but it's also possible to run each part on different servers if needed.

22 === Differences between Apple's and Wonder's versions of the deployment tools ===
23
24 wotaskd and JavaMonitor were released as open source when WebObjects 5.4 was released in 2007. A copy of the source was added to Project Wonder, and [[improvements and bug fixes>>WO:Project Wonder additions to wotaskd and JavaMonitor]] were made on the tools in Project Wonder. We strongly suggest that you use the Wonder version of the tools.
