To create the tree of nodes recursively, ManagementParser2addSubordinates searches at each node for any entries pointing to it, if the node is known to be a manager node from the previous step A static variable, nSearches, keeps track of the number of search operations completed:

The end results are the same as with ManagementParser, but performance is much worse if the organization contains a large number of managers, since each one is searched separately against the directory However, the technique used here progressively expanding the tree by doing a search is useful in many cases If an application expands a subtree lazily (only when a user clicks on a particular node, for example), then the technique may be ef cient

In 10 we used the JTree component from JFC to render the relationships of directory entries JTree takes a DefaultMutableTreeNode as parameter, so we can use the output of ManagementParserparseTree (or ManagementParser2parseTree) to render reporting relationships with no effort However, we would like to display the title of each manager along with the name inside a box, and we would like a tooltip to show the full DN of a node when a user places the cursor over it OrgChartTreeCellRenderer (Figure 12-6) replaces the default renderer for nodes It contains a label for an icon, some space below it, and below that a compo-
