iterating my ApplicationResources

[David Hamilton]

hi there, first time post (^__^ x) and i've got a simple question (i hope)
basically, i want to output all the key pairs in my ApplicationResources
file to a jspa and write them as xml, but i can't find any simple way of
iterating through them. id like something like the code below but open to
advice.

<appvars>
<nested:iterate name="messages">
<appvar>
<key><nested:write property="key" /></key>
<val><nested:write property="val" /></val>
</appvar>
</nested:iterate>
</appvars>

thanks
David
