Question

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?

Answer 1

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);
