Re: iterating over multiple Collections in one loop with JSTL

[David Evans]

   ${list1Item}
   ${list2[status.index]}


the status variable is an instance of LoopTagStatus, which has an index
property that is set by the forEach loop.

I might favor combining the two lists (in your action) into a single
list, each element of which has a list that holds the two items from the
lists. so you'd access it like:


   ${listItems[0]}
   ${listItems[1]}

RE: iterating over multiple Collections in one loop with JSTL

[Samere, Adam J]

How about creating a single list with an object to encapsulate the
values from list1 and list2 in a single entity?

Public class MyClassContainer {
private MyClass1 my1;
private MyClass2 my2;

...
} 

List = ...

myClassContainerList.add(new MyClassContainer(myClass1, myClass2));

Then in the JSP you only need one loop.

Hi,
Is it possible to do with JSTL something like this: 
(Note: size of list1 and list2 are equal) List list1 = getList1(); List
list2 = getList2(); for(int i=0; i
