Hi, i try to use Peers but i have some pb with it.
I get a java.lang.StringIndexOutOfBoundsException: String index out of
range: -1 Exception when call the getAll method of my Test class.
I call this method from a jsp.
Maybe i have not understand at all the way to use peers so if you can give
me some help it will be great.
here is my code
Thanks for your help
