How to get user info like id on the jsr286 portlet?

Hello All,

According to 59.3.3 How to Access User Information in JSR 286 Portlets in Developer guide for developing Portals with Oracle WebCenter Portal and Oracle JDeveloper,

I added user.login.id<span style="font-family: Tahoma, sans-serif; font-size: 10pt;"> in the portlet.xml like following</span>

     <user-attribute>

        <description>User Login Id</description>

        <name>user.login.id</name>

    </user-attribute>

Then I add view.jsp like following.

       <p class="portlet-font">Hi ${user.login.id}(20140529...003)</p>

But, I cannot see the user  id in the portlet.

What's wrong or missed?

Thanks in advance,

bmw
