When J2V8 was first released, all callbacks from JavaScript to Java required a registered Java method. That is, all Java methods that you wished to invoke had to be first registered with J2V8. For some applications this was fine, but it made for a complex programming model. Furthermore you could not use anonymous inner classes or Java 8 lambdas. With J2V8 4, this has changed. J2V8...

Last week I finally published the Node.js bindings for Java. These bindings allow developers to embed the Node.js runtime directly onto the JVM through the Java Native Interface. In March I gave a pre-release presentation at EclipseCon on this work, which was recorded by InfoQ. You can check it out at: https://www.infoq.com/presentations/node4j-nodejs-java. The slides are also available on SlideShare....

When J2V8 was first released, all Java characters passed between Java and V8 were converted to 8bit C-Style strings. For many applications this was just fine, but if your JavaScript contained 16 bit Unicode characters, then you were hosed. https://twitter.com/waynebeaton/status/757609271496286208 With J2V8 4 this has been fixed. All strings are now referenced as uint16_t in C++. Using the JNI API we were able to get the 2 byte string...

J2V8 provides the technology to link V8 and Node.js with the JVM. Using JNI, Java developers can directly call V8 and Node.js APIs. This seamless integration brings improved JavaScript performance, NPM modules and the Node.js APIs to the Java ecosystem. An alternative approach could have been to invoke two separate processes (Java and Node.js) with a service protocol between them. However, one of the advantages of the single...

After over a year of development, I am very excited to announce that J2V8 4 is publicly available on all supported platforms. J2V8 is a set of V8 bindings for Java. This means that you can embed V8 (Google's ultra fast JavaScript engine) into your Java applications. J2V8 4 is built on Node.js, which means you can also integrate Node.js with the JVM (On Windows, Mac and...

Gone are the days of single vendor lock-in, where one technology stack is used across an entire organization. Even small organizations and hobbyists will find themselves mixing technologies in a single project. For years, Java reigned king on the server. Today Node.js is everywhere. But even with the rise of Node.js and popularity of JavaScript, Java continues to shine. Furthermore, few organizations can afford to migrate...

Symmetric cryptographic algorithms are algorithms that use the same key for both encryption and decryption. That is, a Code + Key will produce a Cypher, and the Cypher + Key will produce the Code. Crypto-JS is a popular cryptography library which supports a number of different cryptographic algorithms including Advanced Encryption Standard (AES). Encrypting and decrypting using AES with Crypto-JS is straightforward: [raw] var CryptoJS = require("crypto-js"); // Encrypt...

Tabris.js was designed to help developers build native cross-platform apps using a single JavaScript codebase. We offer many tools to boost efficiency - like the Tabris.js developer app and the cloud build service. With Tabris.js 1.8 we’ve introduced a new enhancement that will make a major difference when it comes to getting things done - an interactive debugger. Setup Tabris.js 1.8 apps on Android can now be debugged...

Earlier this year Microsoft released ChakraCore -- their powerful next generation JavaScript engine -- as an OpenSource project under an MIT license. Microsoft also announced that they would be integrating Chakra with Node.js on Windows. At EclipseSource we have a long tradition of bridging technologies. We brought Eclipse/RCP to the web via RAP; we brought JavaScript as a native platform to mobile devices with Tabris.js; and we brought...

The best way to predict the future is to invent it The software landscape is constantly changing and while software may be eating the world, those who fail to adapt will be swallowed whole. At EclipseSource, we are constantly challenging ourselves to ensure we are working on interesting problems while satisfying our customers' needs. We are continually evaluating the software landscape to ensure that our solutions are not...
