HI
Thanks for ur quick response.
But I think for this I need to create portal component.
But my problem is that, I have created a custom login module .Inside that i have created a simple java class and deploy it as .sda file in the sdm .
Here is the code:
package Test;
import java.io.File;
import java.io.FileWriter;
import java.util.Date;
import java.util.Map;
import javax.security.auth.Subject;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.login.LoginException;
import com.sap.engine.interfaces.security.auth.AbstractLoginModule;
import com.sap.security.api.IUserAccount;
public class pwdExpiryNotification  extends AbstractLoginModule {
public void initialize(Subject arg, CallbackHandler handler, Map map1, Map map2){
          IUserAccount useraccount;
public boolean login() throws LoginException {
          try {
IUser user = UMFactory.getUserFactory().getUser("j2ee_admin");
user.getFirstName());
user.getLastName());
}catch (Exception e) {
e.printStackTrace();
return false;
     /* (non-Javadoc)
@see com.sap.engine.interfaces.security.auth.AbstractLoginModule#commit()
     public boolean commit() throws LoginException {
          // TODO Auto-generated method stub
          return false;
     /* (non-Javadoc)
@see com.sap.engine.interfaces.security.auth.AbstractLoginModule#abort()
     public boolean abort() throws LoginException {
          return false;
     /* (non-Javadoc)
@see com.sap.engine.interfaces.security.auth.AbstractLoginModule#logout()
     public boolean logout() throws LoginException {
          return false;
Can u pls see the code and tell me how could i get the details abt the current login code.
Thanks
