java client
Hallo all,
I have a problem with ClientLoginModule. I code very simple SessionBean and very simple java client which should use ClientLoginModule to authenticate user.
Here are the config files on server-side
<container-configurations>
<container-configuration>
<container-name>Standard Stateful SessionBean</container-name>
<security-domain>java:/jaas/exa1</security-domain>
</container-configuration>
</container-configurations>
etc..
and login-config.xml
<application-policy name = "exa1">
<login-module code = "org.jboss.security.auth.spi.UsersRolesLoginModule"
flag = "required" />
<module-option name = "password-stacking">useFirstPass</module-option>
<module-option name = "unauthenticatedIdentity">nobody</module-option>
<module-option name = "debug">true</module-option>
</application-policy>
On client side I have auth.conf like this:
client-login {
// jBoss LoginModule
org.jboss.security.ClientLoginModule required
;
//password-stacking="useFirstPass"
// Put your login modules that need jBoss here
};
Short snap-shot of client app:
static class AppCallbackHandler implements CallbackHandler {
private String username;
private char[] password;
public AppCallbackHandler(String username, char[] password) {
this.username = username;
this.password = password;
}
public void handle(Callback[] callbacks) throws java.io.IOException,
UnsupportedCallbackException {
for (int i = 0; i < callbacks.length; i++) {
if (callbacks instanceof NameCallback) {
NameCallback nc = (NameCallback)callbacks;
nc.setName(username);
} else if (callbacks instanceof PasswordCallback) {
PasswordCallback pc = (PasswordCallback)callbacks;
pc.setPassword(password);
} else {
throw new UnsupportedCallbackException(callbacks, "Unrecognized Callback");
}
}
}
}
public static void main(String args[]) throws Exception {
if( args.length != 3 )
throw new IllegalArgumentException("Usage: username password example");
System.setErr(System.out);
String name = args[0];
char[] password = args[1].toCharArray();
String example = args[2];
System.out.println("+++ Running SessionClient with username="+name+", password="+args[1]+", example=
"+example);
try {
System.out.println("before new AppCalllback");
AppCallbackHandler handler = new AppCallbackHandler(name, password);
System.out.println("after new AppCalllback");
LoginContext lc = new LoginContext(example, handler);
System.out.println("Created LoginContext");
lc.login();
System.out.println(lc.toString());
System.out.println(lc.getSubject().toString());
} catch (LoginException le) {
System.out.println("Login failed");
le.printStackTrace();
}
try {
InitialContext ctx = new InitialContext();
Object objRef = ctx.lookup("ejb/Salary");
SalaryHome home = (SalaryHome)javax.rmi.PortableRemoteObject.narrow(objRef,
etc.
I run java client with this script:
#!/bin/sh
if [ "x$JBOSS_HOME" = "x" ]; then
JBOSS_HOME="/opt/jboss"
export JBOSS_HOME
fi
$JRE_HOME/bin/java -Djava.security.auth.login.config=auth.conf -classpath .:auth.conf:$JBOSS_HOME/client/jbossall-client.jar:./ejb_sample_client.jar:./ejb_first.jar com.client.SalaryClient "$@"
1. param is username
2. param is paasword
3. param is ID of ClientLoginModule ("client-login") that is spec. in auth.conf
Problem:
On server side I have principal equals to null => I=ve got exception like this:
