{Author Note: this is a placeholder for the initiation of odmjni100.dll development experimentation.  The experiments have been carried out.   The documentation and packaging has not been completed.  It will follow the achievement of the 0.50beta level of ODMJNI 1.0 implementation. }

Setup00 is the first confirmation step for development of the info.odma.odmjni100 Java package and JNI  odmjni100.dll library for use in ODMJNI operations.

The folder tree of Setup00 is structured for installation alongside the source trees for the other portions of ODMJNI 1.0 development: practical100 and OdmNative100.

1. Overview

The Setup stages provide progressive confirmation of the software build configuration, each introducing further levels of Java-OdmNative JNI integration.

Setup00 accomplishes the following:

• Establishment of the build environment for a C Language JNI DLL implementation.
     
• Performance of an equivalent of  "Hello World" using a native method to perform the output.
    
• Use of static native methods, the kind that will be used for odmjni100.
    
• Successful use of javah to generate C Language headers for the native implementation to be provided in a Windows DLL.
     
• Successful construction of a DLL that implements native methods in accordance with the javah-defined interface requirements.
    
• Verification of one way to deploy a JNI DLL without having to create a library path for use by the Java runtime.

Additional details are found in the manifest file for download of the code and scripts.
