I found that if I were to use a simple thing as mailto to a list of user in a String format. i.e. <% String finalEmailList = "email@example.com,firstname.lastname@example.org"; %> <a href="mailto:<%=finalEmailList%>">Email candidate</a> Groupwise does not really like it and only sent email to the first user. Any clue on how to solve this? I have since created a form post thing...but still stuck. I am not sure if I need to introduce Array. If I need to, how could I get the email into array and then pass it via form post? Any help is much appreciated. Thank you.
