Installing SAP JCo on Glassfish server 4.0

In SAP, there is a file intro.html that contains detailed instructions on installation of JCo3 on different Operating Systems.

Following are the instructions:

• To install JCo for Windows unzip the appropriate distribution package into an arbitrary directory {sapjco3-install-path}.
• Note: Do not copy the sapjco3.dll neither into the {windows-dir}\system32 nor into the {windows-dir}\SysWOW64 directory. This will break the operability of other JCo versions that are already installed on the same system. Furthermore you would risk that the current installation also would not work anymore, if the sapjco3.dll gets replaced in the respective Windows system directory in the future.
• Then add {sapjco3-install-path} to the PATH environment variable. Finally, add {sapjco3-install-path}\sapjco3.jar to your CLASSPATH environment variable.

By following above instructions, you can install JCo on different Windows OS.
