PRocessing Multiple "Submit" buttons

Question

I want my JPS to have multiple submit buttons, one for Contineu and one for Cancel. It appears to me that the only way to detect which was clicked in the servlet is pretty inelegantly, something like this:
if(request.getParameter("continue") != null)
// do continue stuff
else
    if(request.getParameter("cancel") != null)
// do cancel stuffIs this correct? Is there a less cumbersome way? Thanks.

I will suggest that you write two servlets one to do cancel action and the other to do continue action and through JS call the servlet of cancel or continue.
that makes your work easier.
Like this
<Script language="JavaScript">
function fn_Perform_Action(chr_User_Action)
               //-- 2.1) -- ADD a record to database
               if (chr_User_Action == "Save")
                         var bln_Ret_Val = fn_Check_Mandatory_Fields();                                                       if (bln_Ret_Val)
                                   document.frm_name.action = "/path";
                                   document.frm_name.submit();
                                   return true;                              
               //--2.3) -- Back to the Menu
               if (chr_User_Action == "Back")
                                   document.frm_name.action = "/path";
                                   document.frm_name.submit();
                                   return true;                              
                    return false;
</script>
<Input Type="Button" Value=" Update " id="id_btn_Save" Name="btn_Save"  OnClick="return fn_Perform_Action('Save');">   
<Input Type="Button" Value="Back" id="id_btn_Back" Name="btn_Back"  OnClick="return fn_Perform_Action('Back');">
</Td>          
</Tr>
