TreeView with Struts framework

[giugy]

Hi, sorry for my english but I don't speak it very well.

Somebody know where I can find the source code to create a treeview with the Struts framework? Better if I can load some data in this treeview...Example: I extract some information from an XML file, the data that I extract from this XML file represent the node of the treeview...so I need to load this data in the treeView so that this treeview has the node that are extract from the XML file....
Example:
data obtain from the xml file
Level1 , Level2 , SubLevel2a , SubLevel2b , Level3, SubLevel3a ....

TreeView
Level1
Level2
->SubLevel2a
->SubLevel2b
Level3
->SubLevel3a
......

Thanks so much,bye.Claudio
