Error creating custom realm on Glassfish 3.1.2.2 (Build 5)

Dear All,

I have been trying to create a custom realm on Glassfish 3.1.2.2 (Build 5) using the Admin console and I got this error below:

Creation of Authrealm engcustomrealm failed. com.sun.enterprise.security.auth.realm.BadRealmException: java.lang.ClassNotFoundException: com.samplerealm.SimpleRealm not found by org.glassfish.main.security [271]

I had previously created a jar file for the custom realm and dropped it in the folder: C:\Program Files\glassfish-3.1.2.2\glassfish\domains\domain1\lib as well updating the file C:\Program Files\glassfish-3.1.2.2\glassfish\domains\domain1\login.conf with the details of the new realm

The jar file contents are as follows:

package com.samplerealm;

import com.sun.enterprise.security.auth.realm.IASRealm;
import com.sun.enterprise.security.auth.realm.InvalidOperationException;
import com.sun.enterprise.security.auth.realm.NoSuchUserException;
import java.util.Enumeration;
import java.util.Vector;
public class SimpleRealm extends IASRealm {

@Override
public String getAuthType() {
return "simple";
}

@Override
public Enumeration getGroupNames(String string) throws InvalidOperationException, NoSuchUserException {
Vector vector = new Vector();
vector.add("Users"); vector.add("Admin");
return vector.elements();
}
@Override
public String getJAASContext()
{
return "simpleRealm";
}
public boolean loginUser(String userName, char[] password)
{
boolean loginSuccessful = false;
if ("glassfish".equals(userName) &&"secret".equals(password.toString()))
{ loginSuccessful = true; }
return loginSuccessful;
}
}

package com.samplerealm;

import com.sun.appserv.security.AppservPasswordLoginModule;
import com.sun.enterprise.security.auth.realm.InvalidOperationException;
import com.sun.enterprise.security.auth.realm.NoSuchUserException;
import java.util.Enumeration;
import javax.security.auth.login.LoginException;

public class SimpleLoginModule extends AppservPasswordLoginModule {

@Override
protected void authenticateUser() throws LoginException {
Enumeration userGroupsEnum = null;
String[] userGroupsArray = null;
SimpleRealm simpleRealm;
if (!(_currentRealm instanceof SimpleRealm))
{
throw new LoginException();
}
else
{
simpleRealm = (SimpleRealm) _currentRealm;
}
if (simpleRealm.loginUser(_username, _passwd))
{
try
{ userGroupsEnum = simpleRealm.getGroupNames(_username); }
catch (InvalidOperationException e)
{ throw new LoginException(e.getMessage()); }
catch (NoSuchUserException e)
{ throw new LoginException(e.getMessage()); }
userGroupsArray = new String[2]; int i = 0;
while (userGroupsEnum.hasMoreElements())
{ userGroupsArray[i++] = ((String) userGroupsEnum.nextElement()); }
}
else
{
throw new LoginException();
}
commitUserAuthentication(userGroupsArray);
}

}

Expecting your contributions guys

Regards,
Tony
