How to authenticate using the AWS Cognito user pool

I created a Cognito user pool. I can list users and add users using the AWSCognitoIdentityProviderClient from the Java AWS SDK.

However, I do have a user login page, and I want to take the username and password I entered and authenticate against my user pool. I do not see anywhere in the Java AWS SDK where I can transfer credentials and receive the authentication result.

Edit: I cannot get through this error:

NotAuthorizedException: missing credentials in config

Relevant Code:

    AWS.config.region = 'us-east-1';
    AWS.config.credentials = new AWS.CognitoIdentityCredentials({
        IdentityPoolId: 'us-east-1:087a3210-64f8-4dae-9e3c...' // your identity pool id here
    });

    AWSCognito.config.region = 'us-east-1';
    AWSCognito.config.credentials = new AWS.CognitoIdentityCredentials({
        IdentityPoolId: 'us-east-1:087a3210-64f8-4dae-9e3c...' // your identity pool id here
    });

    var poolData = {
        UserPoolId: 'us-east-1_39RP...',
        ClientId: 'ttsj9j5...',
        ClientSecret: 'bkvkj9r8kl2ujrlu41c7krsb6r7nub2kb260gj3mgi...'
    };
    var userPool = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(poolData);

    var authenticationData = {
        Username: 'test@foo.com',
        Password: 'foobarfoo',
    };
    var authenticationDetails = new AWSCognito.CognitoIdentityServiceProvider.AuthenticationDetails(authenticationData);
    var userData = {
        Username: 'test@foo.com',
        Pool: userPool
    };
    var cognitoUser = new AWSCognito.CognitoIdentityServiceProvider.CognitoUser(userData);
    cognitoUser.authenticateUser(authenticationDetails, {
        onSuccess: function (result) {
            console.log('access token + ' + result.getAccessToken().getJwtToken());
        },

        onFailure: function (err) {
            alert(err);
        },

    });
