Struts JQuery Tree Assigning Node Specific url using jsone Data - json

Question

I tried the same code as on http://code.google.com/p/struts2-jquery/wiki/TreeTag
It's working fine to generate the tree structure, but I want to assign different URLs to each TreeNode of the tree. How can I do same with JSON response?
A Tree Component with a JSON Data Source.
JSP Code
<s:url var="treeDataUrl" action="json-tree-data"/>
<sjt:tree
id="jsonTree"
href="%{treeDataUrl}"
onClickTopics="treeClicked"
/>
Java Action Code
#ParentPackage(value = "showcase")
public class JsonTreeData extends ActionSupport {
private static final long serialVersionUID = -2886756982077980790L;
private List<TreeNode> nodes = new ArrayList<TreeNode>();
private String id = "";
#Actions( { #Action(value = "/json-tree-data", results = { #Result(name = "success", type = "json", params = {
"root", "nodes" }) }) })
public String execute() {
TreeNode nodeA = new TreeNode();
nodeA.setId("A" + id);
nodeA.setTitle("Node A" + id);
nodeA.setState(TreeNode.NODE_STATE_CLOSED);
TreeNode nodeB = new TreeNode();
nodeB.setId("B" + id);
nodeB.setState(TreeNode.NODE_STATE_CLOSED);
nodeB.setTitle("Node B" + id);
TreeNode nodeC = new TreeNode();
nodeC.setId("C" + id);
nodeC.setState(TreeNode.NODE_STATE_CLOSED);
nodeC.setTitle("Node C" + id);
nodes.add(nodeA);
nodes.add(nodeB);
nodes.add(nodeC);
return SUCCESS;
}
public String getJSON() {
return execute();
}
public List<TreeNode> getNodes() {
return nodes;
}
public void setId(String id) {
this.id = id;
}
}
TreeNode.java
public class TreeNode implements Serializable {
public static final String NODE_STATE_CLOSED = "closed";
public static final String NODE_STATE_OPEN = "open";
private Map<String, Object> attr;
private Collection<TreeNode> children;
private String icon;
private String id;
private String state = TreeNode.NODE_STATE_CLOSED;
private String title;
public TreeNode() {
super();
}
public TreeNode(String title) {
super();
this.title = title;
}
public TreeNode(String id, String title) {
super();
this.id = id;
this.title = title;
}
public TreeNode(String title, Collection<TreeNode> children) {
super();
this.title = title;
this.children = children;
}
public TreeNode(String id, String title, Collection<TreeNode> children) {
super();
this.id = id;
this.title = title;
this.children = children;
}
public Map<String, Object> getAttr() {
return attr;
}
public Collection<TreeNode> getChildren() {
return children;
}
/**
* Get the Tree Node Title
*/
public String getData() {
return title;
}
public String getIcon() {
return icon;
}
public String getId() {
return id;
}
public String getState() {
return state;
}
public String getTitle() {
return title;
}
public void setAttr(Map<String, Object> attr) {
this.attr = attr;
}
/**
* Set the Tree Node Childrens
*
* #param children
*/
public void setChildren(Collection<TreeNode> children) {
this.children = children;
}
/**
* Set the Tree Node Icon
*
* #param icon
*/
public void setIcon(String icon) {
this.icon = icon;
}
/**
* Set the Tree Node Id
*
* #param icon
*/
public void setId(String id) {
this.id = id;
if (this.attr == null) {
attr = new HashMap<String, Object>();
}
if (this.attr.containsKey("id")) {
this.attr.remove("id");
}
this.attr.put("id", id);
}
/**
* Set the Tree Node State open or closed
*
* #param state
*/
public void setState(String state) {
this.state = state;
}
/**
* Set the Tree Node Title
*
* #param title
*/
public void setTitle(String title) {
this.title = title;
}
#Override
public String toString() {
StringBuilder builder = new StringBuilder();
builder.append("TreeNode [id=").append(id).append(", title=").append(
title).append(", icon=").append(icon).append(", state=")
.append(state).append(", attr=").append(attr).append(
", children=").append(children).append("]");
return builder.toString();
}
}
For Each Node It generates output as
<li id="C0" class="jstree-closed jstree-last">
<ins class="jstree-icon ui-icon ui-icon-triangle-1-e"> </ins>
<a href="#" class="ui-state-default">
<ins class="jstree-icon ui-icon ui-icon-folder-collapsed"> </ins>
Node C0
</a>
</li>
I want to assign each node specific url to corresponding anchor tag generated as above.
Any help appreciated, thanks!
