The e4xd sub-project provides the javascript server-side for the Openmocha project, a javascript application server with a "soft-coding" framework. The soft-coding allows modifications and development work from the "inside" of the running web application. The behavior of the web application can be changed in ways that closely relates to the hierarchical content structure of the resulting website, without the need to "hard-code" these changes in code files. Every content object becomes "sovereign" and can define its own behavior, overriding what it would inherit from the hard-coded prototypes or from other soft-coded objects higher up in the content structure hierarchy. The e4xd objectengine leverages naming conventions for hard-coded filenames and soft-coded object property names to overlay the hard-coded and soft-coded properties and methods and determine the behavior of an object at runtime. Internally, these conventions follow the existing ones of the Helma framework, but expand that philosophy, adding additional conventions and accomodating to the needs of the soft-coding environment. The jhino sub-project provides a base application scaffold for the soft-coding environment. It leverages the e4xd object engine and adds an additional layer of conventions, resulting in a basic scaffold for a working base application with CRUD type functionality and access control. Basically, jhino already provides a fully working soft-coding environment, but requires the standard Helma development tools such as the shell and inspector to do the actual "soft-coding". The e4xd javascript server-side currently requires a patched version of Helma and Rhino. In the case of Rhino, e4xd depends on the JOMP patch and Helma needs to be modified to do the additional file suffix mapping required by e4xd. http://dev.helma.org/wiki/Comparison+of+JSAdapter+and+JOMP/ http://dev.helma.org/static/files/2302/helma.txt *** How to get e4xd working On the e4xd.org site, you should be able to find a working build to download and simply start with ./start.sh http://e4xd.org/ In addition to the full openmocha build, there is also a build that contains only the jhino modules and patched jar files, in order to add jhino to your own helma install. You would need to replace the helma.jar and rhino.jar in your Helma install with the patched versions. The "objectengine" and "jhino" modules are expected to be placed in Helma's modules directory and the exampleapp would normally go into Helma's apps directory. You could then start the example app from your manage application or add it to the apps.properties file to have it start automatically. http://localhost:8080/exampleapp *** More info and help Other than what you find on the (possibly not yet existing) e4xd.org website, the best places to get in touch are the openmocha mailing list and google group or the #[email protected] IRC channel. http://groups.google.com/group/openmocha irc://irc.freenode.net/helma http://helma.zumbrunn.com/hopbot/ Also, in case you are new to Helma, you of course need to add the helma.org website and mailing lists to the top of that list. http://helma.org/ To get in touch with me directly, you should find additional contact information on the zumbrunn.com site.
