[FIXED] How to get user roles in a JSP / Servlet

Issue

Is there any way to get a String[] with the roles a user has in the JSP or Servlet?

I know about request.isUserInRole("role1") but I also want to know all the roles of the user.

I searched the servlet source and it seems this is not possible, but this seems odd to me.

So... any ideas?

Solution

Read in all the possible roles, or hardcode a list. Then iterate over it running the isUserInRole and build a list of roles the user is in and then convert the list to an array.

String[] allRoles = {"1","2","3"};
HttpServletRequest request = ... (or from method argument)
List userRoles = new ArrayList(allRoles.length);
for(String role : allRoles) {
 if(request.isUserInRole(role)) { 
  userRoles.add(role);
 }
}

// I forgot the exact syntax for list.toArray so this is prob wrong here
return userRoles.toArray(String[].class);
