Installing SAP JCO

The Master requires Java connector (JCO) software from SAP. SAP’s JCO middleware allows a Java application to communicate with an SAP system. Each operating system requires its own version of the JCO, which can be downloaded from SAP.

To download and install the SAP JCO:

1. Navigate to the this URL in a web browser: http://service.sap.com/patches. A Client Authentication dialog requests an authentication certificate.

2. Do either of these:

   • If you have this certificate, click it and click OK.

   • If you do not have a certificate,

     1. Click OK to display the Enter Network Password dialog.

     2. Enter the user name and password supplied by SAP into the respective text fields and click OK. The SAP Support Packages and Patches web page is displayed.

3. Navigate to 3.x SAP Java Connector Download page.

4. Click the appropriate operating system to access its archive file for downloading. Follow the JCO installation instructions included in the archive file.

   In the initial SAP JCO 3.0 setup, two files from the SAP JCO.zip file are necessary:

   • sapjco3.jar (Windows and Linux)

   • sapjco3.dll (Linux: libsapjco3.so)

5. Add the {sapjco-install-path}/sapjco3.jar} to your CLASSPATH environment variable after installing the JCO. Specify the path to the location of the JCO 3.x libraries. You may need to reboot your system (Windows) if the JCO library is not reflected in the CLASSPATH environment variable.
