NoInitialContextException in a client like "howto" example
Hello,
I test the JAAS example "howto" from Scott Stark. It works.
Then I add the security component to my application.
Like the "howto" example I modify the deployment descriptor files ejb-jar.xml and jboss.xml. Two new files users.properites and roles.properties are also added into the jar package. After successful deploying I try
to access the Bean with a Client like the example. But a exception
is thrown:
...
[java] Created LoginContext
[java] javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an application
resource file: java.naming.factory.initial
[java] at javax.naming.spi.NamingManager.getInitialContext(NamingManage
r.java:643)
...
Source of this client:
---------------------------------
class SecureTestClient {
static class AppCallbackHandler implements CallbackHandler
{ ...
like "howto" example
}
public static void main {
AppCallbackHandler handler = new AppCallbackHandler(name, password);
LoginContext lc = new LoginContext("TestClient", handler);
System.out.println("Created LoginContext");
lc.login();
InitialContext iniContext = new InitialContext();
SessionHome home = (SessionHome) iniContext.lookup("project1/SessionBean1");
Session bean = home.create();
...
}
}
---------------------------------
The statement with "iniContext.lookup("project1/SessionBean1")" cause the exception.
In jboss.xml I give this JNDI-Name "project1/SessionBean1" for a bean.
And I can use this JNDI-Name before I made the changes.
Then I call also my old test client without the LoginContext and try to call lookup
of JNDI direktly and I can get the home reference! But I receive the security exception,
when I want to create a remote object for this home reference.
...
[java] java.rmi.ServerException: RemoteException occurred in server thread;
nested exception is:
[java] java.rmi.RemoteException: checkSecurityAssociation; nested excep
tion is:
[java] java.lang.SecurityException: Authentication exception, principal
=null
...
This exception is expected. My client hasn't used login context.
Has somebody an idea, why does my Client
similar "howto" example get NoInitialContextException?
