Custom JSP taglib. Lets you build HTML-based tree view structures. For example:
 

and you will get the following structure:

You may disable default connectors between nodes and define own pictures for all nodes (for nodes with sub-nodes and without them):
 

node 1

node 1.1    node 1.2       node 1.2.1       node 1.2.2    node 1.3

node 2

Tag addNode lets you define individual pictures for nodes, as well as a link for node picture:
 

and you will get this:

node 1

node 1.1    node 1.2       node 1.2.1       node 1.2.2    node 1.3

node 2

You can define your own connectors:
 

and you will get this:

node 1

node 1.1   node 1.2      node 1.2.1      node 1.2.2   node 1.3

node 2

With DHTML capable browser you can use parameter dhtml. E.g.:
 

and you will get this:

	node 1 node 1.1 node 1.2 node 1.2.1 node 1.2.2 node 1.3
	node 2

You can add scrolling to your tree:
 

and you will get this (try to open all nodes):

	node 1 node 1.1 node 1.2 node 1.2.1 node 1.2.2 node 1.3
	node 2

Also you can create a tree structure in your server side code (e.g. in Struts action) and pass this stricture as a parameter to createTree tag. There are two optional parameters: modelBean - describes an object of com.cj.tree.TreeBean type and modelName - describes a name for the attribute (request, session, page or application scope) for object of com.cj.tree.TreeBean type. TreeBean contains setters and getters for attributes defined for addNode tag. Method getParent() would return the parent of a particular node. For example:
 

and you will get some like this:

Root

Node 1      Node 1.1   Node 2

Tags are:

createTree

body tag creates tree-like structure. Parameters are:

1) treePicture Optional parameter. Describes a picture (image file) for subtrees.
2) openPicture Optional parameter. In DHTML mode you can use own picture for opened nodes.
3) nodePicture Optional parameter. Describes a picture (image file) for leafs.
4) dhtml Optional parameter. Possible values are true and false. Enables/disables DHTML support (client side tree). Default value if false (disabled).
5) defaultConnectors Optional parameter. Possible values are true or false. Enables/disables pseudo-graphics elements between nodes. Default value is true.
6) verticalConnector Optional parameter. Describes your own image for the vertical connector (see examples at the bottom of this page).

8) bottomConnector Optional parameter. Describes your own image for the bottom connector (see examples at the bottom of this page).
9) id Optional parameter. Describes a DHTML (XHTML) id for your tree
10) style Optional parameter. Describes a CSS style.
11) className Optional parameter. Describes a CSS class

4) pictureLink Optional parameter. Defines a link for the picture
5) id Optional parameter. Describes a DHTML (XHTML) id for this node
6) style Optional parameter. Describes a CSS style for this node.
7) className Optional parameter. Describes a CSS class for this node
8) open Optional parameter. Possible values are true or false. Describes a state for sub-tries (opened/closed). Default value is true (opened).
9) showAsFolder Optional parameter. Possible values are true or false. If this value is true node will be shown always as a folder (the parent's treePicture value will be used). Default value is false.
10) statusText Optional parameter. Describes a text in the status line for the hyperlinks
11) codeLink Optional parameter. Possible values are true or false. If this value is true than node's code (label) will present a hyperlink for the opening/closing too. Default value is false.

setCode

Body tag defines a code (text) for the node. Parameters are: none.

Note: the evaluation version supports up to 5 nodes
