After looking through the documentation, mailing lists, and this forum, it appears that the key of a map within the application context can only be a string.

Code:
<map>
   <entry key="string">
       <value>"the value"</value>
   </entry>
 </map>
Is there a way around this? I'd like use instances of my own class as the key.
I found a few discussions on this topic but no resolution. Unless, of course there isn't one.

Thanks.
