Exception: principal=null
Hi,
i have a Problem with user authentication.
I have written something like that
--------------------------Servlet-----
...
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
try {
String name = req.getParameter("name");
int id = Integer.parseInt(req.getParameter("id"));
int age = Integer.parseInt(req.getParameter("age"));
int stock = Integer.parseInt(req.getParameter("stock"));
double price = Double.parseDouble(req.getParameter("price"));
WhiskeyDO whiskey = new WhiskeyDO(id, name, price, stock, age);
ManagerHome mh = ManageWhiskey.managerHome();
ManagerRemote manager = mh.create();
manager.addWhiskey(whiskey);
Collection c = manager.listAll();
req.setAttribute("list", c);
this.getServletContext().getRequestDispatcher("/ListWhiskeys.jsp").forward(req, res);
}
catch (Exception e)
{
throw new ServletException(e);
}
}
private static ManagerHome managerHome() throws Exception
{
try
{
AppCallbackHandler handler = new AppCallbackHandler("uname","passwd".toCharArray());
LoginContext lc = new LoginContext("Test",handler);
lc.login();
}
catch(Exception e)
{
System.err.print(e.toString());
return null;
}
return (ManagerHome)PortableRemoteObject.narrow(
new javax.naming.InitialContext().lookup("pub/Manager"),
bar.ManagerHome.class);
}
...
----jboss.xml @ ManagerBean dir--------------
...
<security-domain>java:/jaas/pub</security-domain>
<enterprise-beans>
<ejb-name>
Manager
</ejb-name>
<jndi-name>
pub/Manager
</jndi-name>
</enterprise-beans>
---------$JBOSS_HOME/server/default/conf/login_config.xml----------------
...
<!-- Used by clients within the application server VM such as
mbeans and servlets that access EJBs.
-->
<application-policy name = "pub">
<login-module code = "org.jboss.security.auth.spi.UsersRolesLoginModule"
flag = "required">
</login-module>
</application-policy>
...
I don't know any solution for the Problem below.
Can somebody help me?
Thx.
