You need to add to your portlet.xml something like
| Code Block |
|---|
| xml | xml |
|---|
| title | Declaring a user attribute in portlet.xml |
|---|
| xml |
|---|
|
<user-attribute>
<description>User Family Name</description>
<name>user.name.family</name>
</user-attribute>
|
...
Then from within your Portlet code you can access the values like this
| Code Block |
|---|
java |
|---|
| java |
|---|
| title | Accessing a user attribute from JSR-168 Java implementation |
|---|

Map userInfo = (Map)request.getAttribute(PortletRequest.USER_INFO);
String surname = (String)userInfo.get("user.name.family");
