Integrating Low Code Tools with Java Applications

Let's see how these low code and no code (LCNC) tools can be seamlessly integrated into Java-based applications, enhancing their capabilities and functionalities. Below are examples of how some prominent tools can be integrated:

1. Spring Boot

Spring Boot provides a simplified approach to backend development in Java. By integrating Spring Boot into a Java application, developers can create robust and efficient backend services with minimal configuration. Here's a basic example of integrating Spring Boot into a Java-based application:


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

‍

In this example, the @SpringBootApplication annotation initializes the Spring Boot application context, allowing developers to focus on building the business logic.

2. Vaadin

Vaadin enables Java developers to create modern and responsive user interfaces for web applications. Integration with Vaadin streamlines UI development using Java. Here's a simple example of integrating Vaadin into a Java-based application:


import com.vaadin.flow.component.button.Button;
import com.vaadin.flow.component.notification.Notification;
import com.vaadin.flow.component.orderedlayout.VerticalLayout;
import com.vaadin.flow.router.Route;

@Route
public class MyUI extends VerticalLayout {

    public MyUI() {
        Button button = new Button("Click me",
                event -> Notification.show("Hello from Vaadin!"));
        add(button);
    }
}

‍

In this example, the Vaadin components are utilized to create a basic UI layout with a button that triggers a notification when clicked.

3. Joget DX

Joget DX offers a visual approach to application development, allowing developers to design workflows, forms, and user interfaces without extensive coding. Integrating Joget DX can expedite the creation of Java-based applications. Here's an illustration of integrating Joget DX:

import org.joget.apps.app.service.ProcessUtil;

public class MyJogetApp {

    public void createNewProcessInstance(String processDefId) {
        ProcessDefinition processDef = ProcessUtil.getProcessDefinitionById(processDefId);
        ProcessUtil.startProcess(processDef, AppUtil.getCurrentUser());
    }
}

‍

In this example, Joget DX's APIs are leveraged to create a new process instance based on a specified process definition.

4. AppGyver

AppGyver provides a visual development environment for creating cross-platform applications with minimal coding. Integrating AppGyver allows Java developers to build applications swiftly. Here's an example of integrating AppGyver:

    public void connectToOutSystems() {
        JavaConnector connector = new JavaConnector("myOutSystemsConnector");
        connector.connect();
    }
}

‍

In this example, the JavaConnector class from OutSystems is used to establish a connection to the OutSystems platform.

6. Nected

Let's explore how Nected seamlessly enhances the functionality of your React.js application, similar to the previous example. We'll guide you through a code snippet that vividly demonstrates how Nected can be effortlessly integrated into a React.js project, resulting in remarkable outcomes.


import React, { useState, useEffect } from 'react';
import axios from 'axios';

const App = () => {
    const [responseMessage, setResponseMessage] = useState('');

    // Define Nected API / webhook URL
    const nectedWebhookURL = '';

    // Sample parameters to determine product price
    const priceParams = {
        environment: 'staging',
        isTest: false,
        params: {
            customer_location: 'sample-value',
            product_name: 'sample-value'
        }
    };

    useEffect(() => {
        // Trigger the Nected API with product & customer params
        axios.post(nectedWebhookURL, priceParams)
            .then(response => {
                if (response.status === 200) {
                    setResponseMessage('Nected rule & workflow triggered successfully!');
                } else {
                    setResponseMessage('Error triggering Nected API.');
                }
            })
            .catch(error => {
                console.error('Error triggering Nected API:', error);
                setResponseMessage('Error triggering Nected API.');
            });
    }, []);

    return (
        
            {responseMessage}

        

    );
};

export default App;

‍

This example showcases how Nected seamlessly integrates with your React.js application, enhancing its capabilities. The code snippet details the step-by-step process of invoking a Nected rule and workflow using its API. Here's a breakdown:

Defining Nected API URL: The process begins by defining the Nected API or webhook URL associated with a specific rule or workflow within the Nected ecosystem.
Sample Parameters: A set of sample parameters is thoughtfully structured to determine the product price. These parameters are encapsulated within the priceParams object.
Triggering Nected API: The axios.post method orchestrates the invocation of the Nected API, transmitting the nectedWebhookURL and the priceParams as JSON data.
Response Handling: The response from the API call is assessed. If the response status code is 200, it signifies the successful execution of the Nected rule and workflow. In case of any issues during the API invocation, an error message is displayed.

Through this illustration, the seamless synergy between Nected and React.js becomes evident, enabling you to seamlessly integrate Nected's capabilities into your application workflow, even when working with Java.

7. JHipster

JHipster is a development platform that generates Java-based applications using Spring Boot and Angular or React. Integrating JHipster can expedite the creation of modern applications. Here's an example of integrating JHipster:

public class MyJHipsterApp {

    public void configureJHipsterProperties() {
        JHipsterProperties properties = new JHipsterProperties();
        properties.getSecurity().setContentSecurityPolicy("default-src 'self';");
    }
}

‍

Here, the JHipsterProperties class is used to configure security settings in a JHipster-based application.

8. Mendix

Mendix is a low-code platform that enables developers to build, test, and deploy applications without extensive coding. Integrating Mendix into a Java-based application can enhance rapid application development. Here's an example of integrating Mendix:

    public void createNewMendixObject() {
        MendixObject mendixObject = new MendixObject("MyEntity");
        mendixObject.setValue("attribute1", "value1");
        mendixObject.commit();
    }
}

‍

In this example, the MendixObject class is used to create and manipulate objects in a Mendix-based application.

These examples demonstrate how various Java-centric low code/no code tools can be seamlessly integrated into Java-based applications, expanding their functionalities and providing developers with powerful solutions for rapid application development.
