SAP JCo libraries for Mac OS

SAP JCo(Java Connectors) libraries would be required to connect to the SAP server.  Basically it will have sap JCo ‘jar’ file as well as sap JCo native library file.

For example. If you are connecting using JCo3 jars, below would be required based on the operating system.

§  sapjco3.jar: JCo Java runtime libraries – This would be same for 32 bit and 64 bit systems

§  [prefix]sapjco3.[extension]: JNI runtime library that contains JCo native code. The target operating system determines the prefix and file name extension:

§  Windows: sapjco3.dll

§  MacOS: libsapjco3.jnilib

Note: Ensure that the libraries you use are correct for your 32-bit or 64-bit system.

   osgi.parentClassloader=ext
   This file is available at <Eclipse_Installation_Path>/configuration.
