Open Source Java Interface Engines

J2ObjC is an open-source command-line tool from Google that translates Java source code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java source to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as application logic and data models) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. J2ObjC supports most Java language and runtime features required by client-side application developers, including exceptions, inner and anonymous classes, generic types, threads and reflection. JUnit test translation and execution is also supported. J2ObjC cannot convert Android binary applications. Developers must have source code for their Android app, which they either own or are licensed to use.

CB2XML (CopyBook to XML) is a COBOL CopyBook to XML converter written in Java and based on the SableCC parser generator. This project includes utilities to convert an XML instance file into its COBOL copybook equivalent string buffer and vice versa. Source is now available in GitHub: https://github.com/bmTas/cb2xml

This is a fork of the jamod Modbus library, taken at version 1.2.1, released under the Apache 2 license, as contained in the SVN repository for that project. The goal of the j2mod project is to produce a more fully functioning Modbus(tm) communication library based on the Java programming language. It is the intention that this be an actively developed project, accepting submissions from professional software engineers with experience in Modbus Master and Slave development.

A real-time graph plotter. While your application is computing and logging results to a CSV file using the LiveGraph Writer API, the plotter lets you visualise and monitor the results live - by instantly plotting charts and graphs of the data.

Dynamic COBOL copybook parser for Java. Supports parsing and writing of application data based on parsed copybooks. Coverts COBOL types to Java types and back to COBOL types with validation.

RxtxConsole is an API and GUI software, developed by Doidx with JSerialCom as the kernel. It can be used for multi- UART/RS232 interface operation. The platform supports Windows/MAC/Linux. Note: Developed with Java17 Follow these steps step by step to apply RxtxConsole, 1. LIST, to obtain all Serial ports currently available on the system. 2. CONNECT, Select a Serial port for connection and place it in the connection pool for use 3. CONNECTED, check that the Serial ports are connected. Sometimes, the Serial ports that you try to connect may have been used by other applications. 4. USE, select a connected serial port for which the command is transmitted only. 5. Start p2p communication with each other, ex: SCPI... 6. If you want to make other Settings on the system, you can USE SYS to change
