Hi Bob -
Thank you very much for pointing me in the right direction. This is exactly
what I was missing...how to connect Spring Security's authentication result
with a Page class.
In the end, I used the following approach, which is nearly identical to your
suggestion. I couldn't get getContext().getRemoteUser() to work as my project
didn't recognize the getContext method. I Googled it and it seemed to suggest I
needed the servlet.jar in my classpath. That still didn't resolve the fact that
it couldn't recognize getContext(). So I decided to browse through the Page API
and found the slightly different approach as shown below in case it helps
anyone else with a similiar issue. I used the getContext() from
org.apache.Click.Page:
@Component
public class WelcomePage extends BorderPage {
String loginName = getContext().getRequest().getRemoteUser();
//Then used Apache Cayenne to bring back the details on the User object passing
in loginName.
Thanks again..
Conor

Subject: Re: Spring Security and Apache Click - Obtaining username after login?
Hi Conor,
After you've logged on with Spring Security the username is available through
the Servlet API:
http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/http/HttpServletRequest.html#getRemoteUser()
You wouldn't normally display the login name to the user, but rather lookup the
user account and
display the firstname.
public class MyPage extends BorderPage {
public void onInit() {
String loginName = getContext().getRemoteUser();
Customer customer = getCustomerDao().getCustomerByLoginName(loginName);
addModel("name", customer.getFirstName());
}
}
mypage.htm
Welcome $name
Hope this helps.
kind regards
bob
