The SAP BEx connector requires an SAP account to download their java connector : JCO.

Prerequisites

Activating the data source

To deploy the SAP BEx connector, you will need to:

  • Stop the DigDash server
  • Deploy the libsapjco3.so (linux) or sapjco3.dll (windows) and sapjco3.jar files in the $CATALINA_HOME/shared/lib folder. To find the value of CATALINA_HOME, you can look for CATALINA_HOME in Tomcat's startup logs, or you can execute the catalina.sh or catalina.bat file with the version parameter.
  • Configure the shared.loader property in the $CATALINA_BASE/conf/catalina.properties file:

    shared.loader="${catalina.base}/shared/lib","${catalina.base}/shared/lib/*.jar","${catalina.home}/shared/lib","${catalina.home}/shared/lib/*.jar"
  • Configure java.library.path by adding the following option to the CATALINA_OPTS:

    -Djava.library.path=/path/to/shared/lib
  • Activate the data source in DigDash:
    in the <webapps>/ddenterpriseapi/WEB-INF/classes/resources/config/tabledsrepository.xml file:

    <!-- <TableDataSource id="SAPBEXDS" name="$ui.SAPBEX.Popup" shortName="$ui.SAPBEX.Short" description="$ui.SAPBEX.DSDesc" iconBaseName="ds-sapbex.png" manufacturer="DigDash"
         class="com.digdash.tabledatasources.SAPBEXDataSource"
         uiclass="com.digdash.userinterface.dialogs.SAPBEXPreviewPanel"
         categ="$ui.DsCategDB">
     <properties>
     </properties>
    </TableDataSource>
     -->

    should be changed to:

    <TableDataSource id="SAPBEXDS" name="$ui.SAPBEX.Popup" shortName="$ui.SAPBEX.Short" description="$ui.SAPBEX.DSDesc" iconBaseName="ds-sapbex.png" manufacturer="DigDash"
        class="com.digdash.tabledatasources.SAPBEXDataSource"
        uiclass="com.digdash.userinterface.dialogs.SAPBEXPreviewPanel"
        categ="$ui.DsCategDB">
    <properties>
    </properties>
    </TableDataSource>
  • Start the DigDash server
