Answer 1

You need to pass the variable to ActionMEssage like this,

       errors.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage(
                "error.plan.foundForUser", new Object[] {"username"}));

@sarah, what struts version are you using? @zz's code looks right to me and it shouldn't give you compilation error. By the way, if you want to append a list of users into {1} param, you probably need to loop through the users using StringBuilder to construct the "denormalize" string.

// loop through the list to construct comma delimited user names    
String allUsers = ...; 

errors.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage(
                "error.plan.foundForUser", "allUsers"));
