| 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 | |||
| |
12.1 | 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. |

| |
12.1 | 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. |
| |
7.1 | 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 | |||
| |
12.1 | 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. |

13.1 | 28 | 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. |
