Sorry thomas, i downloaded and checked on GateIn 3.6. Thanks for your advice i am going to delete my post from jboss portal fourm. Also i am expecting an answer for my above problem

Thanks Nick

I am sure that i am logged in with as  user in GateIn. But the user page worked if  i add that user under predefinedOwner tag in portal-configuration.xml like following way

       <object-param>

            <name>user.configuration</name>

            <description>description</description>

            <object type="org.exoplatform.portal.config.NewPortalConfig">

              <field name="predefinedOwner">

                <collection type="java.util.HashSet">

                  <value>

                    <string>manager</string>

                  </value>

                  <value>

                    <string>admin</string>

                  </value>

                </collection>

              </field>

              <field name="ownerType">

                <string>user</string>

              </field>

              <field name="templateLocation">

                <string>war:/conf/portal</string>

              </field>

            </object>

          </object-param>

(In above manager and admin can create user page because they are under predefinedOwner tag )

But in the case of adding  user page for users who are added programatically i got the above exception. I am using the following code for adding users programatically

OrganizationService orgService = (OrganizationService)PortalContainer.getInstance().getComponentInstanceOfType(OrganizationService.class);

User user =new UserImpl("supervisor");

user.setPassword("supervisor");

user.setEmail("supervisor@gmail.com");

user.setFirstName("supervisor");

user.setLastName("supervisor");

orgService.getUserHandler().createUser(user, false);
