Vertical and horizontal drag/drop node tree

I was recently experimenting with a html tree which can manipulate it's nodes by drag and drop. I wanted to make it horizontally and vertically growable. When I was almost done, I had to rush for a much simpler version of this without the drag/drop part. I think the code I have written so far might be a good starting point to someone who is trying to do the same thing.

Download Code

The above code use script.aculo.us Prototype and YUI javascript libraries together. Now I am realizing that, using YUI alone might be a better solution for this since YUI also comes with the drag/drop support.

Projecting HTML Elements on a circle using Javascript

Recently I wonted to create a tree control with a different approach. The requirement was to represent a node tree with main node on the circle center and it's child nodes projected on a circle around it. This is what i wanted. My solution has 5 files prototype.js This is a handy javascript framework. You can download the latest version from there website ( www.prototypejs.org/download ). I am using this to simply handle the onload event in the page. circle.html script.js node-main-left.gif node-sub-left.gif The circle.html, prototype.js and the script.js files are in the root folder and the two images are inside a folder named “images”. This is how the html file looks(circle.html). <html> <head> <script src="prototype.js" type="text/javascript"></script> <script src="script.js" type="text/javascript"></script> <script language="javascript" xml:space...

Role of GREG permission-mappings.xml

GREG has a permission-mapping.xml. We can find it at /home/chanaka/Desktop/greg/wso2greg-5.2.0/repository/conf/etc/permission-mappings.xml Each entry has three attributes. managementPermission resourcePermission resourcePaths Ex: managementPermission="/permission/admin/manage/resources/govern/server/list" resourcePermission="http://www.wso2.org/projects/registry/actions/get" resourcePaths="/_system/governance/trunk/servers" /> There are default configurations in this file. These entries are mapping each permission in the permission tree in to resource paths and assign them permissions. With the above line in the permission-mappings.xml, an admin user who assign the permission " /permission/admin/manage/resources/govern/server/list " will be able to do get operations on registry resources stored at " /_system/governance/trunk/servers ". We can provide multiple resource paths by separating them by comas. There...
