Ok, then I inesert groovy code between 2 velocity bloc to sort my map:
...
#end ##Fin foreach
$xcontext.put("xSiglesArray", $SiglesArray)
#end ## fin temporaire pour insérer le code groovy
{{/velocity}}
{{groovy}}
if(xcontext.get("xSiglesArray")){
SiglesArrayGv = xcontext.get("xSiglesArray");
// Trie le tableau (insensitive case )
SiglesArrayGv=SiglesArrayGv.sort { it.key.toLowerCase() };
xcontext.put("xSiglesArray", SiglesArrayGv);
xcontext.put("DoRegen", true);
}
{{/groovy}}
{{velocity}}
##
##Regénére la page et trie les entrées (suite)
#if ( $xcontext.get("DoRegen")== 'true' && $xcontext.get("xSiglesArray") )
##
#set ($SiglesArray= $xcontext.get("xSiglesArray"))
#foreach($Anchor in $AnchorsArray)
##
Thxs

I tried to decrypt Javadoc and I found I could use:
String.CASE_INSENSITIVE_ORDER

($myHashMap =
$collectionstool.getSortedMap(String.CASE_INSENSITIVE_ORDER,
String))

Velocity is very far from supporting Java
syntax. Plus here you seems
to be mixing
CollectionsTool and TreeMap javadoc. CollectionsTool
contains only one getSortedMap() method and it
has no parameter.
There
does not seems to be any way to get a TreeMap configured
with
String.CASE_INSENSITIVE comparator in
Velocity. The main issue is that
you
can't create an object or access a static variable in
Velocity so
no way to use a method that
takes a Comparator as parameter even if
there was one (which is not the case for
maps).
Right now the only
alternatives seems to be:
* use Groovy
* write a script service in Java that provide
the feature
* patch CollectionsTool to add a
way to pass a comparator to the various methods
