Custom Tag doubt

Question

I am trying to use custom tags in my JSP. I have illustrated the simplified version of my problem below. Can anyone tell me how to go about doing it?
Problem definition:
I have a JSP in which I retrieve a hashtable from request object using request.getAttribute() method. I need to display the commodity details present in the Hashtable using custom tags.
Input Hashtable contents(given in Key: Value format)
"Commodity.length": "2"
"Commodity[0].Weight": "34"
"Commodity[1].Weight": "43"
Please note that the above keys are not Java arrays, they are just strings
Required JSP format
<gan:array name = "Commodity">
<table>
  <tr>
  <input type='text'
         name='<gan:getFullNameForItem name="Weight" />'
         value='<gan:getValueForItem name="Weight" />'   />
  </tr>
</table>
</gan:array>
Desired HTML output:
<table>
  <tr>
  <input type='text'
         name='Commodity[0].Weight'
         value='34'  />
  <input type='text'
         name='Commodity[1].Weight'
         value='43'  />
  </tr>
</table>
My question:
How can I go about implementing the tags starting with "gan:"?
Please note that there can be nested gan:array tags.
