I can realize my group, I give some part of my code for people in need ^^.

This code create group of vertex 
(I retrieve my graph vertice "g.getVertices()" and With some criteria in userdatum
of my vertex I create the group)

Set verticeGroup[] = new Set[1000];
int nbrGroupe=2; // number of group you want
	 	
for(int i=0;i<=nbrGroupe;i++)
{
    verticeGroup[i] = new HashSet();
}

vertices=g.getVertices();
Iterator iterator = vertices.iterator();
while(iterator.hasNext())
{
    Object tmp=iterator.next();
    		
    ArchetypeVertex toto=(ArchetypeVertex)tmp;
    //after that if u using a bean with your userdatum u have to cast
    BeanPage tmp2=(BeanPage)toto.getUserDatum("acceder");
    System.out.println("vertices "+tmp2.getNom());
    System.out.println("vertices number of the group
"+tmp2.getNumeroDeGroupe());
    		
    //we had the item ( tmp) to the good group
    for(int i=0;i<=nbrGroupe;i++)
    {
        if(tmp2.getNumeroDeGroupe() == i )
    	{
            verticeGroup[i].add(tmp);
    	}
    }
}

//and for each group you add it in a sublayout
for(int i=0;i<=nbrGroupe;i++)
{
    if(verticeGroup[i].size() <= layout.getGraph().numVertices()) 
    {
    	Point2D center =
layout.getLocation((ArchetypeVertex)verticeGroup[i].iterator().next());
    	SubLayout subLayout = new CircularSubLayout(verticeGroup[i], 20, center);
    	layout.addSubLayout(subLayout);
     }
}


nb: BeanPage is a bean i use to stock information about my vertex and I add
it to userdatum of vertex with the key "acceder".

I hope this would help somebody.
^_^
