Hack OpenJDK with NetBeans IDE
You've come to the right spot if you are trying to hack OpenJDK with NetBeans IDE. This article explains what OpenJDK with NetBeans is and how you can use NetBeans to create OpenJDK. But before we dive in, first things first: What are Hack OpenJDK and NetBeans IDE? Open Java Development Kit (JDK) is an open-source implementation of the Java Platform or Standard Edition. That means anyone can access the source code and GNU General Public license of the OpenJDK. You may also ask, "then what is Netbeans?" NetBeans is also an open-source integrated development environment for developing with Java, PHP, C++, and other programming languages. All THE applications are developed modules in Java. The OpenJDK repository contains a NetBeans project for all C/C++ parts of the OpenJDK, including Hotspot. So, since NetBeans is an Apache project, it is pretty easy to download and hack the code. You can run it on operating systems like Windows, Linux, and macOS. Remember, to use NetBeans for Java programming; you first need to install Java Development Kit (JDK). Can I use NetBeans with OpenJDK? Yes, you can. The latest NetBeans version of NetBeans is at NetBeans IDE 6.0 Beta 1. But keep this in mind, to hack OpenJDK, you'll need only the Java SE version. Which JDK is compatible with NetBeans? The JDK is compatible with JDK 8 features. That includes annotations, compact profiles, lambda expressions, and repeatable. When you use any of those constructs in your code, they will automatically highlight errors and allow you to fix syntax. Review, Hacking, and Develop OpenJDK. You follow these simple: Get OpenJDK, as follows: #hg clone http://hg.openjdk.java.net/jdk8/build jdk_trunk #cd jdk_trunk #sh get_source.sh #mkdir build #cd build #sh ../configure. After you’ve "configured", the step is complete, remember the value assigned to "Boot JDK" and then:#export IDE_ALT_BOOTDIR=jdk_path_found_by_configure #netbeansStart NetBeans IDE (with C++ support) and open projects from "common/nb_native". Just make sure that the project already contains configurations for Solaris, Linux, and macOS. You can do this by switching to the appropriate configuration and enjoying hacking OpenJDK. Next up, navigate inside your NetBeans project directory. Once there, you will find a directory called incubator-Netbeans. This directory contains sufficient NetBeans modules. Is OpenJDK with NetBeans IDE secure? As the emphasis increases, so does the need for security. Hence, you can easily create the Secure Directories. You can do this by choosing File > New Project (Ctrl-Shift-N), selecting Web Application from the Java Web category, and clicking Next. Regression testing verifies that system changes do not interfere with existing features or code structure. They are part of almost every test suite in software development lifecycles. It is common for developers to change or add a code section and unintentionally disrupt something that is working just fine. Visual regression testing functions on the same logic but confines it to the visual aspects of the software. It works by comparing two images and automating complicated scenarios, like when we cannot identify the elements in the DOM tree. However, visual regression can be used on any website. How Does Visual Regression Testing Work? During the first run, the visual comparison tool captures the snapshot called the base image. The subsequent run compares the base image if there is no difference test is passed, and if there is a difference, the test is considered as failed. Visual regression is also called visual comparison testing. In this tutorial, we will discuss automated visual regression using Playwright. Prerequisites for Visual Regression with Playwright Download and install NodeJS Download and install Visual Studio Code (Recommended) Install Playwright NPM module Install @playwright/test module Note Throughout this tutorial, we are using Playwright with JavaScript. Playwright comes with the default visual comparison tool, so there is no need to install additional packages. Create Simple Visual Comparison Tests Using Playwright In your tests folder, create a new JavaScript file example demo.spec.jspage.screenshot() function takes the screenshot, and expect in the @playwright/test module provides the assertion for matching the images that are .toMatchSnapshot(). Inside the newly created JavaScript file, create a new test that performs the visual comparison like below. Visual Comparison in Playwright to Ignore Minor Differences The above comparison technique matches the screenshot pixel by pixel, which means each pixel should match exactly. This behavior can be modified by passing the argument maxDiffPixels = . Example JavaScript const { test, expect } = require('@playwright/test'); test('Visual Comparison Test Demo', async ({ page }) => { await page.goto('https://playwright.dev'); expect(await page.screenshot()).toMatchSnapshot({ maxDiffPixels: 200 }); }); In the above example, we have specified the maxDiffPixels value as 200, which means the maximum pixel difference can be 200. Image Comparison in Playwright With Threshold Option Playwright toMatchSnapshot() accepts threshold, threshold ranges from 0 to 1, default value is 0.2. The threshold is tolerance of image differences. Example Code JavaScript const { test, expect } = require('@playwright/test'); test('Visual Comparison Test Demo', async ({ page }) => { await page.goto('https://playwright.dev'); expect(await page.screenshot()).toMatchSnapshot({threshold:0.5}); }); In the above code, the threshold is mentioned as 0.5. Playwright Visual Comparison Tips and Tricks In Playwright, we can pass the image file name; instead of default comparison, Playwright compares with the specified filename. Example expect(await page.screenshot()).toMatchSnapshot('home.png'); Playwright also allows us to compare element snapshots; we can take a snapshot of DOM elements and compare. Example expect(await page.locator('xpath=//*[@id="__docusaurus']).screenshot()).toMatchSnapshot(); Visual Regression With Playwright Using Percy Percy is a web-based tool for visual testing with a free tier, and it provides both manual and automation capability for visual comparison. Percy supports Playwright integration. Percy is now a part of Browserstack. If you already have a BrowserStack account, you can sign in with BrowserStack or sign up and create one. Using Percy With Playwright Step 1 – Install Percy modules using the following command. npm install --save-dev @percy/cli @percy/playwright Step 2 – Create a new JavaScript Playwright test file like below. JavaScript //demo.spec.ts const { chromium } = require('playwright'); const percySnapshot = require('@percy/playwright'); (async () => { const browser = await chromium.launch(); const page = await browser.newPage(); await page.goto('https://www.browserstack.com/', { waitUntil: 'networkidle' }); await percySnapshot(page, 'Example Site'); await browser.close(); })(); In the above example, we are navigating to https://www.browserstack.com/, and we are taking a snapshot using the percySnapshot() function. Setting Up Percy Step 1 – Login to Percy. If you don’t have an account, create one. Step 2 – Create a new project. Step 3 – Copy Percy token. Step 4 – In your Visual Studio Code Terminal, set the PERCY_TOKEN environment variable using the below commands: Powershell / Visual Studio Code Terminal $env:PERCY_TOKEN = "your_token"

Building a REST Service That Collects HTML Form Data Using Netbeans, Jersey, Apache Tomcat, and Java
The Jersey project is very well documented so it makes it easy to learn REST with Java. In this article I’m going to build two projects. The first project will be a very simple HTML page that presents a form to the user and then submits it to a REST project residing on the same server. The second project will be the REST part. For this article I used the following tools: 1. Netbeans 7 2. Apache Tomcat 7 3. Jersey 4. Java I built this on OS X Lion. Go ahead and create a new Maven Web Application with Netbeans 7 called: MyForm Once the project has been generated take the resulting (default) index.jsp file and delete it. In its place add a file called: index.html and add the following content to it: Name: Message: Item 1: Item 2: Basically, I created a simple (ugly) form that takes a few parameters the user enters. They submit the form and the data is sent to the REST project we will soon be building. The idea here is we are using an HTTP POST to create a new message. That’s it for the first project! With Netbean’s Maven integration do a Clean and Build and then deploy the resulting WAR file to Apache Tomcat. Create another new Maven Web Application with Netbeans 7 called: RESTwithForms Add two new Java classes to the new project: 1. MyApplication 2. MessageResource The code for MyApplication.java is as follows: package com.giantflyingsaucer; import com.sun.jersey.api.core.PackagesResourceConfig; import javax.ws.rs.ApplicationPath; @ApplicationPath("/") public class MyApplication extends PackagesResourceConfig { public MyApplication() { super("com.giantflyingsaucer"); } } In a brief nutshell this code allows us to make use of some Servlet 3.0 goodies (we don’t need to create a web.xml file for this project as an example). For more details see the sections titled: Example 2.8. Reusing Jersey implementation in your custom application model and Example 2.9. Deployment of a JAX-RS application using @ApplicationPath with Servlet 3.0 at this link. The real guts of the REST project are in the MessageResource.java file as seen below: package com.giantflyingsaucer; import java.net.URI; import java.util.List; import java.util.UUID; import javax.ws.rs.FormParam; import javax.ws.rs.POST; import javax.ws.rs.Path; import javax.ws.rs.core.Response; import javax.ws.rs.Consumes; import javax.ws.rs.core.MediaType; @Path("/messages") public class MessageResource { @POST @Consumes(MediaType.APPLICATION_FORM_URLENCODED) public Response createMessage(@FormParam("name") String name, @FormParam("message") String message, @FormParam("thelist") List list) { if(name.trim().length() > 0 && message.trim().length() > 0 && !list.isEmpty()) { // Note 1: Normally you would persist the new message to a datastore // of some sort. I'm going to pretend I've done that and // use a unique id for it that obviously points to nothing in // this case. // Note 2: The way I'm returning the data should be more like the commented // out piece, I am being verbose for the sake of showing you how to // get the values and show that it was read. return Response.created(URI.create("/messages/" + String.valueOf(UUID.randomUUID()))).entity( name+ ": " + message + " --> the items: " + list.get(0) + " - " + list.get(1)).build(); // This is a more real world "return" //return Response.created(URI.create("/messages/" + String.valueOf(UUID.randomUUID()))).build(); } return Response.status(Response.Status.PRECONDITION_FAILED).build(); } } Note: Pay special attention to the comments. Please don’t email me stating I shouldn’t be returning text back with the values, also please don’t tell me I should be iterating the list, etc. this is just a demo. You will obviously do this differently in a production environment. The key here is simplicity and minimal code. At this point you need to add jersey-server as a dependency in your POM file. com.sun.jersey jersey-server-linking 1.9.1 With Netbean’s Maven integration do a Clean and Build and then deploy the resulting WAR file to Apache Tomcat. You are now ready to test it out. Load up the HTML file from the first project and enter some data and then submit it. If you have a tool like FireBug for Firefox, you can also see that an HTTP 201 was returned (if successful). If you don’t enter any data in the form then you should get an HTTP 412 back. With not much more work you could just as easily use something like jQuery and submit the form via AJAX.
