[xwiki-users] object not transfered with include macro

Hello I'm using the "include macro" to transfer some information between the different documents of my xwiki, but somehow I can't transfer any class. When I try this code : First page : {{groovy}} xy=2; public class Souris { public String Name; public Souris(){ Name="Jerry"; } } Souris Verte = new Souris(); {{/groovy}} Second page : {{include reference="First page"/}} {{groovy}} println(xy); {{/groovy}} {{groovy}} println(Verte.Name) {{/groovy}} the first groovy macro runs well and displays 2 as predicted, but the second one doesn't work. Why ? And how can I make it work? Thanks for the advice ! Adrien
