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.
