Hi how would I go about retrieving the princiopals after login in my web app?

Bassically I would like to know the users PrincipaID (username) and roles.

Thanks

See http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3859817

The isCallerInRole on the EJBContext object can be used to test user roles, and the isUserInRole on the HttpServletRequest can be used to do the same in a servlet context.

There is no standard J2EE way to get the list of role of a user.

Am trying this as I need it in my web container not ejb...

request.getPrincipal.getName()

But i get...

An error occurred at line: 10 in the jsp file: /artists/profile_form.jsp
Generated servlet error:
D:\jboss-4.0.0\server\default\work\jboss.web\localhost\mamoth\org\apache\jsp\artists\profile_005fform_jsp.java:52: cannot resolve symbol
symbol : variable getPrincipal
location: interface javax.servlet.http.HttpServletRequest
out.print(request.getPrincipal.getName());
^
1 error

Sorry more specifically, I would like to know the username (PrincipalID) that is loged in to my web site, so i can use that PrincipalID to query the DB for additional information.

As sugested in the other post, request.getPrincipal.getName(), throws an exception as shown in the previous post.

I also wanted to do this through filter so I can create a bean and pass it along through a session, so i wont have to query the DB for the extra info again.

Thanks

Agree, it was typed a little too quickly, but you should, at least, check the javadoc of the javax.servlet.http.HttpServletRequest class.
getPrincipal is a method, not a public instance variable (Java 101 ...).
Try request.getPrincipal().getName() instead.

But i will try this!

[infectedrhythms]

Still no go!

According to...

http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/http/HttpServletRequest.html

There is no getPrincipal()

[infectedrhythms]

it's request.getUserPrincipal().getName()

Thanks
