5		-WebObject's wotaskd and JavaMonitor deployment tools were open sourced in WebObjects 5.4. The source was then quickly modified and included in Project Wonder. Substantial improvements in both functionality and look-and-feel have been made over the years since their release as open source. These improved versions of **wotaskd.woa** and **JavaMonitor.woa** are available as full Wonder applications.
	7	+JavaMonitor is a web-based tool used to configure and maintain deployed WebObjects applications. It is capable of handling multiple WebObjects applications, multiple instances of each application, and multiple WebObjects Applications Servers. In most cases you'll have one instance of JavaMonitor controlling all instances of your applications, even if they are spread across multiple Application Servers.

	9	+wotaskd (WebObjects task daemon) is the WebObjects Deployment tool that manages the instances on an Application Server. It's used by Monitor to propagate site configuration changes throughout the site's application hosts.

	11	+Apple released the original wotaskd and JavaMonitor to the community as open source in WebObjects 5.4. The source was then quickly modified and included in Project Wonder. Substantial improvements in both functionality and look-and-feel have been made over the years. These improved versions of **wotaskd.woa** and **JavaMonitor.woa** are available as standard Wonder applications.

80	80	You can do most of the standard tasks you do in Monitor by calling direct actions. They are in a different query handler, ///admin//. They follow the same format and use the same query parameters. Those DA can be useful if you need to restart instances or other tasks within ant or other build/deployment systems.

132	132	This feature, from my understanding, allow you to upload new versions of your app, start up the new version and refuse sessions for the instances running on the older version. I don't know how this will work if your new version use migrations to change your schema (eg : old instances might raise exceptions because of database schema changes), so try it out on a test server before and put your results here.

136	136	On September 28th 2010, REST routes were added in JavaMonitor. Those routes + the direct actions explained in this document allow you to control almost everything remotely (make sure that your JavaMonitor installation is secure). As the direct actions, append //?pw=XXXX// to the URLs if JavaMonitor is password protected.
