Sure,
I would recommend that you have a look at the Tomahawk examples for
tree2 and go from there. You will only need one or two facets,
depending on if you decide to show the files in the tree or not.
Example:
<t:tree2 var="_folder" value=#{bean.folderModel}">
<f:facet name="folder">
<t:commandLink action="#{bean.loadContents">
<t:updateActionListener
property="#{bean.selectedFolder}"
value="#{_folder}" />
</t:commandLink>
</f:facet>
</t:tree2>
