Introduction

Call a Fortran dynamic library (DLL) from Java bean by using JNI/JNA.

JNI

Demo (\bin folder)

This demo is allowing the invocation of one or many DLL. JNI, Java Native Interface, is giving access to the C++ code which is encapsulating the Fortran code. As a test, two parameters (XML files) are sent through the FortranExecuter class to the FortranExecuter.dll library. In return, a message is sent back from the library to the java code.

To achieve the operation, the library FortranExecuter.dll should be call by the fortrandll1.dll library.

Content

  • Parameters sent by the FortranExecutor.class
    • [IN] (string) : 'c:\processor\incoming\in.xml'
    • [IN] (string) : 'c:\processor\outcoming\out.xml'
    • [OUT] (integer) : 100 (value code 'no error' sent back from the library)
  • DLL files
    • FortranExecuter.dll interface that allows to invoke n sub-DLL(s)
    • fortrandll1.dll called by FortranExecuter.dll and which is containing the Fortran code

Test

To test the application,

  1. Go to the '\bin' folder
  2. Copy the FortranExecuter.dll DLL to this place : 'C:\FortranExecuter.dll'
  3. Start run.bat

Note, as a test an OK message code (100) should be returned by the library.

Requirements

You might need a few things for your environment (PATH) such as,

  • Java JDK 8
  • Compilers,
    • Gnu gfortran (MinGW)
    • Gnu g++ (MinGW)
