Hi
Use CallBackHandler and GSS to get AS400 object
This is code i have
//BeanCallbackHandler.java
import java.io.IOException;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.NameCallback;
import javax.security.auth.callback.PasswordCallback;
import
javax.security.auth.callback.UnsupportedCallbackException;
public class BeanCallbackHandler
implements CallbackHandler
{
String name;
String password;
public BeanCallbackHandler(String name, String
password)
{
this.name = null;
this.password = null;
this.name = name;
this.password = password;
}
public void handle(Callback callbacks[])
throws UnsupportedCallbackException,
IOException
{
for(int i = 0; i < callbacks.length; i++)
{
Callback callBack = callbacks[i];
if(callBack instanceof NameCallback)
{
NameCallback nameCallback =
(NameCallback)callBack;
nameCallback.setName(name);
} else
if(callBack instanceof PasswordCallback)
{
PasswordCallback passwordCallback =
(PasswordCallback)callBack;
passwordCallback.setPassword(password.toCharArray());
} else
{
throw new
UnsupportedCallbackException(callBack, "Call back not
supported");
}
}
}
}
//LoginGSS.java
import java.security.PrivilegedAction;
import javax.security.auth.Subject;
import javax.security.auth.login.LoginContext;
import org.apache.log4j.Logger;
import com.ibm.as400.access.AS400;
// Referenced classes of package com.pfizer.maps.data:
// BeanCallbackHandler
public class LoginGSS
implements PrivilegedAction
{
private String as400Name;
private Logger logger;
public LoginGSS()
{
logger =
Logger.getLogger(this.getClass().getName());
}
public Object getAS400(String userId, String
password, String as400Name)
throws Exception
{
this.as400Name = as400Name;
String confName = "GSSClient";
BeanCallbackHandler beanCallbackHandler = new
BeanCallbackHandler(userId, password);
LoginContext lc = new LoginContext(confName,
beanCallbackHandler);
lc.login();
logger.debug("logged in successfully ");
Subject sub = lc.getSubject();
return Subject.doAs(sub, this);
}
public Object run()
{
try
{
// System.out.println("in run method ");
AS400 as400 = new AS400(as400Name);
// AS400Con as400 = new
AS400Con(as400Name,"", "", "2");
// as400.getAS400().connectService(2);
//System.out.println("create as400
oject");
as400.connectService(2);
logger.debug("user " + as400.getUserId() +
" system " + as400.getSystemName());
return as400;
}
catch(Exception exc)
{
logger.error(exc.getMessage());
exc.printStackTrace();
}
return null;
}
}
Apart from that you will need a krb5.ini file and
login.conf file in tomcat application server,
You can google information about krb5.ini file

We are using the techniques detailed in the
"Windows-based Single Signon and the EIM Framework"
Redbook. User/password authentication is performed
by a Windows Active Directory server. iSeries
authentication is performed by EIM/NAS. I have it
working for iSeries Access and NetServer but now I
need to get JT400.jar to work.
Does anyone have any samples or references?
