Is there a utility somewhere in Struts or the Commons that pulls subset of objects from a collection based on a String array of values?
Here's what I mean: I have a collection of objects that have label and value fields so I can use them in the Struts multibox tag. Struts returns a String array of the values that were selected. Now I want to get a collection of the objects the user selected based on the contents of the String array. So, they selected item 5, 19 and 23. I'm looking for a one-step way to pull objects 5, 19 and 23 from a collection of all the objects. I've looked at the Collections methods but don't see a way to get anything but one item from a HashMap. I've looked at BeanUtils, but couldn't find anything. So, I'm iterating through the collection, which works, but it seems like such a common routine that it'd already be available. Is it? Dave
