Installing the SAP Java Connector

To retrieve data from SAP ERP (BAPI data sources) or from SAP BW / SAP BI (with multidimensional data sources with the BAPI adapter), install the SAP Java Connector 3.1 (SAP JCo).

You can do this at another time; you do not need to do it right after installing the Denodo Platform.

Installing the Connector

Follow these steps to install the SAP JCo connector:

  1. On Windows, SAP JCo requires you to install the Visual Studio 2013 C/C++ runtime libraries on the computer in which the Denodo Platform is installed.

    If this library is not present or you are unsure, follow these steps:

    1. Go to https://support.microsoft.com/en-us/help/4032938 to download the Microsoft Visual C++ Redistributable Package.

    2. In this page, download the file: vcredist_x64.exe. Select the version for the language of your operating system.

      This is the file for 64-bit operating systems and applications that run with the 64-bit version of the Java Virtual Machine (the one included with the Denodo Platform).

    3. Execute the downloaded file and follow the installation instructions.

  2. Go to https://support.sap.com/en/product/connectors/jco.html.

    • For Windows, download the version for Microsoft Windows and Windows Server - 64-bit x86 processor.

    • For Linux, download the version for the processor of this computer.

  3. Decompress the downloaded file

  4. Log in with the Administration Tool with an administrator account.

  5. Click the menu File > Extensions management.

  6. Click the tab Libraries and then, click Import.

  7. In the new dialog, in Resource type, select sapjco.

  8. In Version, select the version you are going to upload.

  9. Click Add and select these files:

    1. sapjco3.jar

    2. If Virtual DataPort runs on Windows, sapjco3.dll

    3. If Virtual DataPort runs on Linux, libsapjco3.so

    To select more than one file, hold the key Ctrl and select each file.

  10. Click Ok to upload the file(s) to Virtual DataPort.

  11. Restart the Virtual DataPort server after the files upload is completed.

Testing the Connector on Windows

If the Denodo Platform is installed on Windows, connect to the computer where it is installed, open a command line and execute the following commands. This is to test that the JCo connector has all the dependencies it needs.

cd <DENODO_HOME>
cd extensions\thirdparty\sap-jco
..\..\..\jre\bin\java.exe -jar sapjco3.jar -stdout

You should see something like this:

Java Runtime:
 Operating System:    Windows 10 10.0 for amd64
 Java VM:             11.0.8 AdoptOpenJDK
 Default charset:     windows-1252
Versions:
 JCo API:             3.1.3 (2020-09-18)
 JCo middleware:      JavaRfc 2.10.1
 JCo library:         753.710
Library Paths:
 JCo archive:         C:\Denodo\Denodo Platform-8.0\extensions\thirdparty\lib\sap-jco-connector\sapjco3.jar
 JCo library:         C:\Denodo\Denodo Platform-8.0\extensions\thirdparty\lib\sap-jco-connector\sapjco3.dll

In the last two lines, you should see the path to the files sapjco3.jar and sapjco3.dll. If you see something like “JCo library: not loaded, caused by java.lang.UnsatisfiedLinkError: … Can’t load IA 32-bit .dll on an AMD 64-bit platform” it means that the file sapjco3.dll is the 32-bit version of the file and you should copy the 64-bit one.

If you configured Virtual DataPort to run a Java Runtime Environment (JRE) that is not the one included out of the box, execute this command with that JRE to make sure that at runtime, the SAP JCo connector will work.

Testing the Connector on Linux

If the Denodo Platform is installed on Linux, connect to the computer where it is installed, open a command line and execute the following commands. This is to test that the JCo connector has all the dependencies it needs.

cd <DENODO_HOME>
cd extensions/thirdparty/sap-jco
../../../jre/bin/java -jar sapjco3.jar -stdout

You should see something like this:

Java Runtime:
 Operating System:    Linux 4.14.186-110.268.amzn1.x86_64 for amd64
 Java VM:             11.0.8 AdoptOpenJDK
 Default charset:     UTF-8
Versions:
 JCo API:             3.1.3 (2020-09-18)
 JCo middleware:      JavaRfc 2.10.1
 JCo library:         753.710
Library Paths:
 JCo archive:         /opt/denodo/denodo-platform-8.0/extensions/thirdparty/lib/sap-jco-connector/sapjco3.jar
 JCo library:         /opt/denodo/denodo-platform-8.0/extensions/thirdparty/lib/sap-jco-connector/libsapjco3.so

In the last two lines, you should see the path to the files sapjco3.jar and libsapjco3.so. If you see something like “JCo library: not loaded, caused by java.lang.UnsatisfiedLinkError: … Can’t load IA 32-bit .so on an AMD 64-bit platform” it means that the file sapjco3.so is the 32-bit version of the file and you should copy the 64-bit one.

If you configured Virtual DataPort to run a Java Runtime Environment (JRE) that is not the one included out of the box, execute this command with that JRE to make sure that at runtime, the SAP JCo connector will work.
