I understand and share your concern, this is the reason why I brought up
the issue in the first place. I would love to use the a standard way to
achieve this, but I have't got an answer to my question yet: how can I
make this kind of recursive function work with the standard XSP methods,
without tying myself to a particular XSP engine implementation?

Something like this:

<xsp:page>
	<xsp:logic>
		private ?? what does it return ?? BuildTree( FolderTree
tree) throws Exception
		{
			Folder folder =3D tree.getRoot();
			long ID =3D folder.getId();

			<folder>
			<xsp:attribute
name=3D"ID"><xsp:expr>String.valueOf(ID)</xsp:expr></xsp:attribute>
=09
<name><xsp:expr>folder.getName()</xsp:expr></name>

			if (tree.getNodes() !=3D null)
			{
				for (int i =3D 0; i <
tree.getNodes().length; i++)
				{
=09
<xsp:expr>BuildTree(tree.getNodes()[i])</xsp:expr>
				}
			</folder>
			}
		}
	</xsp:logic>
<page>
	<xsp:logic>
		int UserID =3D 1;
		FolderTree tree =3D FolderUtility.getTreeByUser(UserID,
UserID);
	</xsp:logic>
	<xsp:expr>BuildTree(tree)</xsp:expr>
</page>

</xsp:page>

The example is probably syntactically incorrect, but you should get the
basic idea what I'm aiming at...
