Custom MAIN.JSP adding URL for email needs email var

Question

IDM 7.1
Hello forum members!
I have a very small request in this topic; I'm a newbie to IDM and started mods of forms/menus via BPE.
I am customizing /idm/user/main.jsp to display an url where the user can send and email, rather than creating a workflow form, etc...
Now, I can display the easy part which is the current logged in user, but how do I display in the main.jsp the user's email so I can attach it to the url.
Here are my test lines:
right after:
<%@ include file="userHeader.jsp" %>
<br>
<%
String loggedInUser = _wsSess.getUser();
String urlparm = response.encodeURL( "/url/email.html?LANG=" + wps_lang + "&CO="wps_cntry"&USR="+loggedInUser );
<a href="<%= urlparm %">>Click here to send email...</a></p>
right before
<%@ include file="userFooter.jsp" %>

I tried the code above but no luck... my userID has no permissions to the view apparently...
I keep getting errors... which java library should I include? I tried com.waveset.ui.FormUtil but no luck....
=================
org.apache.jasper.JasperException: An exception occurred processing JSP page /user/main.jsp at line 48
45: <br>
46: <%
47: String loggedInUser = _wsSess.getUser();
48: WSUser user = (WSUser)_wsSess.getObject(Type.USER, loggedInUser);
AND THEN FURTHER DOWN...
root cause
com.waveset.util.WSAuthorizationException: View access denied to Subject am1234 on User: am1234.
