Custom tags: passing in maps or other datatypes that arent strings

I needed to pass a hashmap into a custom tag. This hashmap was to be created on the jsp page using jstl, and then passed into the tag as an attribute.
For some reason i was not able to find the solution with just one google query.


1. first, to create a hashmap on the jsp using jstl and add some stuff to it:

2. next, add another attribute to your tag in the tld file:

3. finally, pass the hashmap into your tag .. <tag someName="${something}" /> and make sure that the setter in the tag takes in a Map
