download PDF

The Red Hat Fuse SAP Tool Suite makes it possible to integrate your Camel routes with a remote SAP Application Server. A variety of SAP components are provided to support Remote Function Calls (RFC) and the sending and receiving of Intermediate Documents (IDocs). The SAP Tool Suite depends on the JCo and IDoc client libraries from SAP. To install and use these libraries, you must have an SAP Service Marketplace Account.

8.1. Installing the Red Hat Fuse SAP Tool Suite

Overview

The Red Hat Fuse SAP Tool Suite provides the Edit SAP Connection Configuration dialog, which helps you to create and manage the SAP Application Server and Destination connections. The suite is not installed by default, because it requires third-party JCo and IDoc client libraries, which are licensed separately by SAP.

Platform restrictions for SAP tooling

Because the SAP tool suite depends on the third-party JCo 3.0 and IDoc 3.0 libraries, it can only be installed on the platforms that these libraries support. For more details about the platform restrictions for SAP tooling, see Red Hat Fuse Supported Configurations.

Prerequisites

Before you can install the Fuse SAP Tool Suite, you must download the JCo and IDoc libraries from the following location:

To download these libraries, you must have an SAP Service Marketplace Account. Be sure to choose the appropriate JCo and IDoc libraries for your operationg system. Also:

  • Only version 3.0.11 or greater of the JCo library is supported.

8.5. Create a New SAP Endpoint

Overview

You can use the Components palette in the route editor to add SAP components to a route with the help of the Edit SAP Connection Configuration dialog.

Note

If you are using the SAP Connection view, remember to paste the requisite SAP connection configuration data into your Blueprint XML or Spring XML code.

Prerequisites

You must already have created some SAP destination connections and/or server connections with the help of the Edit SAP Connection Configuration dialog.

Note

If you are using the SAP Connection view, export this configuration to a file of the appropriate type (Blueprint XML or Spring XML).

Procedure

To create a new SAP endpoint, perform the following steps:

  1. It is assumed that you already have a Fuse project and a Camel XML file to work with (which could either be in Blueprint XML or Spring XML format).

  2. Open your Camel XML file in the route editor. If you have already installed the Red Hat Fuse SAP Tool Suite, you should be able to see the SAP components under the Components palette in the route editor. The following SAP components are provided by the tool suite:

    • SAP IDoc Destination
    • SAP IDoc List Destination
    • SAP IDoc List Server
    • SAP qRFC Destination
    • SAP Queued IDoc Destination
    • SAP Queued IDoc List Destination
    • SAP sRFC Destination
    • SAP sRFC Server
    • SAP tRFC Destination

    • SAP tRFC Server

      In the Design tab of the route editor, drag one of these components onto the canvas to create a new SAP endpoint in the current camelContext.

      Note

      The SAP Netweaver component does not belong to the Red Hat Fuse SAP Tool Suite. It is hosted in the Apache Camel project.

  3. Switch to the Source tab of the route editor, by clicking the Source tab at the bottom of the canvas. You can see the XML source of the routes.

  4. When specifying an SAP endpoint URI, you must embed either a destination name or a server connection name in the URI format. For example, the sap-srfc-destination component has the following URI format: 

    sap-srfc-destination:destinationName:rfcName

    To reference a particular destination, use the value of the relevant entry element’s key attribute as the destinationName in this URI.
