Hi,
First of all, Thanks NigelWhite & scott stark .
Yes, We need to specify <security-domain> element in jboss.xml. Then only,
the PolicyContext.getContext method will return Subject otherwise it will
return null.
And it should have same value as <security-domain> element in jboss-web.xml.
And If you add <security-domain> element in jboss.xml, then you must specify
<method-permission> element for your EJBs, otherwise you can't access your EJBs
from servlet or jsp.
(First I wrongly understood, I thought to get Subject from EJB we must use
CustomLogin module, Sorry, Its not correct, the key thing is <security-domain>
element in jboss.xml)
For those who need sample code
The following is by my session bean's business method
public String sayHello() {
| try {
| Subject
mySubject=(Subject)PolicyContext.getContext("javax.security.auth.Subject.container");
| return mySubject.toString();
| }catch(Exception e) {
| throw new EJBException("sayHello method failed to get subject",e);
| }
| }
The following my jboss.xml assembly descriptor part
| <assembly-descriptor>
| <method-permission>
| <unchecked/>
| <method>
| <ejb-name>HelloEJB</ejb-name>
| <method-name>*</method-name>
| </method>
| </method-permission>
| </assembly-descriptor>
The following is my Hello.jsp code
<%@ page import="javax.naming.InitialContext, javax.rmi.PortableRemoteObject,
hello.*" %>
| <%
| InitialContext ctxt=new InitialContext();
| HelloHome
home=(HelloHome)PortableRemoteObject.narrow(ctxt.lookup("java:comp/env/ejb/HelloEJB"),HelloHome.class);
| Hello hello=home.create();
| %>
|
|
| <html>
| <head>
| <style type="text/css">
| body {
| font-family:'Comic Sans MS';
| font-size:11pt;
| }
| </style>
| </head>
| <body>
| <%=hello.sayHello()%>
| </body>
| </html>
and this is the output
Subject: Principal: user2 Principal: Roles(members:employee,manager)
Thanks again
