Re: Iterate a Set of data

private Set<Abc> riskSummaryRpt;
{ riskSummaryRpt.add("1"); riskSummaryRpt.add("2"); riskSummaryRpt.add("3");  }

[#list riskSummaryRpt as x]
   ${x}
[/#list]

2 3 1

That will show the values as they are ordered in the underlying collection (already different from what you need).  Sets are not ordered collections.  You may need to change your implementation from HashSet<T>() to LinkedHashSet<T>() which will preserve the order of the items as they are inserted.  You may also want to consider using a List<T> and ArrayList<T>() since your collection is ordered in real life - the only difference there would be you're losing the grouping and allowing duplicates which the set will do differently.

The freemarker code you posted is not doing any ordering.  It's just printing out blobs of text based on the ordering of the underlying collection (which is unordered).  As Daniel previously stated.  If you can't order the backend collection, you'll have to make your template a lot smarter to perform the ordering (probably doing string building or building a parallel index array and even two passes).

order mean , what i put in the out put. it's not like that afetr run it.
if the first record is totalVariance, and second record is factor in the collection.
the output like as below.
                     <totalVariance>
                             <risk>12.32</risk>
                     </totalVariance>
                    <factor>
                        <risk>12.32</risk>
                     </factor>
                     <specific>
                         <risk>12.32</risk>
                     </specific>

But i need the order of what i put in the template.

What ordering are you expecting? The order of the riskSummaryRepors
will be the same as the Set gives them to FreeMarker.
