1	1	=== Introduction ===
2	2
3		-wotaskd and JavaMonitor were open sourced when WebObjects 5.4 was released in 2007. In 2008 and 2009, the source was modified and included in Project Wonder. This is the list of additions that were added to the Wonder versions of the tools.
	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.

	9	+=== Where to get them ===
	10	+
	11	+You can either download them pre-built from [[Wonder's Hudson build server>>http://webobjects.mdimension.com/hudson/job/Wonder54/lastSuccessfulBuild/artifact/dist/]] or build them from the source code.
	12	+
	13	+To build them from the source, simply run the following Command from the Wonder directory at the root of the Wonder source code directory:
	14	+
	15	+{{code}}
	16	+ant frameworks deployment.tools -Dwonder.patch=54 -Ddeployment.standalone=true

	21	+* *ant*: calls Ant
	22	+* *frameworks*: tells Ant to build the "frameworks" target
	23	+* *deployment.tools* tells Ant to build the "deployment.tools" target
	24	+* *\-Ddeployment.standalone=true*: argument will embed the required Wonder and WebObjects frameworks in the wotaskd.woa

113	113	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.

117		-wotaskd and JavaMonitor are now full Wonder applications, and needs Ajax.framework, ERExtensions.framework, ERJars.framework, JavaWOExtensions.framework and JavaMonitor.framework to work correctly. If you get wotaskd.woa and JavaMonitor.woa from the //Wonder-latest-Applications-54// archive, those frameworks are NOT embedded inside wotaskd.woa and JavaMonitor.woa, so either build them from source and embed the frameworks or copy the frameworks into the //appserver// user home (on OS X 10.5, it's in ///var/empty//).
	135	+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.
