CheerpJ Revitalizes Legacy Java Applications

CheerpJ is a Java-to-Javascript runtime and compiler that can convert any Java application to HTML5 for in-browser rendering. CheerpJ 2.0, which features WebAssembly support, was released earlier this month.

According to its developers, Leaning Technologies, a company which provides WebAssembly solutions, its use-case scenarios are threefold :
  • The conversion of legacy Java applications and Java Applets to HTML5 with minimal or no effort, to extend their life until deprecation, or until a replacement native HTML application has been developed.
  • The migration of an existing Java client to a browser-based web application, usually by converting the business logic from Java to WebAssembly/JavaScript with CheerpJ, and rewriting the UI in native HTML.
  • Using (converted) Java libraries as part of a native web application.

Greenplum's Cloudberry Fork Enters Apache Incubator

  Cloudberry is the open source equivalent of Greenplum. Now it is fostered by the Apache Foundation as it acquires incubating status. It all began about six months ago. Greenplum's Github repositories was archived and went dark. This meant no more free new releases or security and bug fixes for its users. Why? Because in May 2024, Tanzu made the decision to close-source the project. https://www.i-programmer.info/news/84-database/17694-greenplums-cloudberry-fork-enters-apache-incubator-.html
