SAP JCo download

The SAP Java Connector (short “JCo”) is a development library that enables a Java application to communicate with on-premise SAP systems via SAP’s RFC protocol. The following version of this JCo driver is required:

  • SAP Java Connector 3.1

A download package is available on the SAP Support Portal [SAP JCo]. You must download the required files if you use MetadataSync for ERP or Messaging for ERP:

  • sapjco30P_<OS-INFO>….zip

    With the following files (that can show a version instead of X):

    • libsapjco3.so / sapjco3.dll

    • sapjcoX.jar

Any owner of SAP software has specific accounts dedicated to the own specific SAP systems to access the SAP Support Portal where the JCo package can be downloaded, which includes all required libraries. Do not take just any SAP Support Portal account to download the required package but make sure to use the account belonging to the SAP system which is in focus. If T-Systems installs ImageMaster in the customer’s name, then the customer must provide this downloaded package to T-Systems (or any other service provider who is responsible for the installation). To identify download packages, try searching for “Java Connector” on the SAP Support Portal [SAP Support]. Usually you will find the packages here:

  • SAP Support Portal > Home > Products > Connectors > SAP Java Connector

You only need the 64-bit version of the SAP Java Connector if you are using a 64-bit Java VM. If you have to use a 32-bit Java VM on a 64-bit platform, download and use the 32-bit version of JCo. The 64-bit variant should always be preferred on 64-bit platforms. The matching operating system of the ImageMaster environment must also be chosen when downloading the JCo package.

You must consider a downtime if the installation is foreseen in a running environment, as the application server needs to be restarted for the changes to take effect.

The following JAR file that you need to obtain by downloading the package is relevant for the JCo installation (which shows a version number instead of X):

  • sapjcoX.jar

Follow these steps to install the JCo drivers on a Linux based system such as RHEL:

  1. Obtain the JCo SDK ZIP package from the SAP Support Portal (e.g. sapjcoXx1P_4-20009381.zip).

  2. Extract the ZIP (e.g. by unzip “sapjcoXx1P_4-20009381.zip”).

  3. Extract the package (e.g. by “tar sapjco3-linuxx86_64-3.1.4.tgz”).

  4. Copy the JAR file sapjcoX.jar into your installation directory. See the system manuals for details:
