title	Configure with IDoc adapter

WSO2 SAP adapter can be used with IDoc, which is a synchronous interface used when exchanging data with the SAP system. WSO2 EI can be configured for Sending IDocs or Receiving IDocs when using the SAP adapter.

Sending IDocs

Follow the instructions below to configure the ESB Profile as an IDoc client using the SAP adapter.

Uncomment the following line in <EI_HOME>/conf/axis2/axis2.xml file to enable the IDoc transport sender on axis2 core.
Code Block
language xml
<transportSender name=”idoc” class="org.wso2.carbon.transports.sap.SAPTransportSender"/>

Create IDocSender proxy service with the following configuration:

Code Block

language	xml

<proxy xmlns=http://ws.apache.org/ns/synapse 
       name="IDocSender"
	   transports="http" 
       startOnLoad="true" 
       trace="enable" 
       statistics="enable">
    <target>
      <inSequence>
         <log level="full"/>
         <send>
         <endpoint name="sapidocendpoint">
             <address uri="idoc:/SAPSYS"/>
         </endpoint>
         </send>
      </inSequence>
      <outSequence/>
   </target>
   <parameter name="serviceType">proxy</parameter>
   <description/>
</proxy>

Info
The SAP endpoint client properties file `SAPSYS.dest` should be in `<EI_HOME>/conf/sap` folder. Additional axis2 level sender parameters that can be defined in the axis2 core are listed in SAP Transport Sender Parameters.

You can now send IDocs using the configured WSO2 SAP adapter.

Receiving IDocs

Follow the instructions below to configure the ESB Profile as an IDoc server using the SAP adapter.

Uncomment the following line in <EI_HOME>/conf/axis2/axis2.xml file to enable IDoc transport receiver in axis2 core.
Code Block
language xml
<transportReceiver name=”idoc” class="org.wso2.carbon.transports.sap.SAPTransportListener"/>
Ensure the server configuration file SAPSYS.server is available in <EI_HOME>/conf/sap folder.
Start the ESB Profile of WSO2 EI using the -Djava.library.path switch to specify the location of your SAP jco library.
For example, you can execute the following command to start the ESB Profile:
Code Block
./integrator.sh -Djava.library.path=/usr/lib/jvm/jre1.7.0/lib/i386/server/

Create the IDocReceiver proxy service with the following configuration:

Code Block

language	xml

<proxy xmlns=http://ws.apache.org/ns/synapse 
       name="IDocReceiver"
       transports="idoc" 
       statistics="enable" 
       trace="enable" 
       startOnLoad="true">
   <target>
     <inSequence>
         <log level="full"/>
         <drop/>
    </inSequence>
    <outSequence>
        <log level="full"/>
        <send/>
    </outSequence>
  </target>
  <parameter name="transport.sap.enableTIDHandler">enabled</parameter>
  <parameter name="transport.sap.serverName">SAPSYS</parameter>
  <description/>
</proxy>

Info
The SAP endpoint server properties file `SAPSYS.server` should be in the `<EI_HOME>/conf/sap` folder. Additional proxy level listener parameters that can be defined in the proxy configuration are listed in Proxy Service Listener Parameters.

Once the proxy service configuration is saved, WSO2 SAP adapter is now ready to receive IDoc messages.

Following are descriptions of the SAP client properties that can be defined in the message context with axis2-client scope when using the ESB Profile of WSO2 EI as a SAP client to send messages. These properties can be added in <EI_HOME>/conf/axis2/axis-client.xml file:

Property Description

transport.sap.xmlMapper The key of custom IDOC XML mapper to use. This key should be defined in the transport.sap. customXMLMappers parameter. If no key is specified the default IDoc XML mapper will be used.

transport.sap. xmlParserOptions

The options for the default IDoc XML parser to be used in the default IDoc XML mapper. Multiple options can be combined using the bitwise OR "|" operator. The possible parser options are as follows:

PARSE_ACCEPT_ONLY_XMLVERSION_10 3328
PARSE_ACCEPT_ONLY_XMLVERSION_11 2816
PARSE_ACCEPT_ONLY_XMLVERSIONS_10_TO_11 2304
PARSE_IGNORE_INVALID_CHAR_ERRORS 4
PARSE_IGNORE_UNKNOWN_FIELDS 2
PARSE_REFUSE_UNKNOWN_XMLVERSION 256
PARSE_REFUSE_XMLVERSION_10 512
PARSE_REFUSE_XMLVERSION_11 1024
PARSE_WITH_FIELD_VALUE_CHECKING 1
PARSE_WITH_IGNORE_UNKNOWN_FIELDS 2
PARSE_WITHOUT_FIELD_DATATYPE_CHECKING 8

Following are descriptions of the proxy level listener parameters that can be defined in a proxy configuration when using the ESB Profile of WSO2 EI as a SAP server:

Parameter	Description
`transport.sap.serverName`	The name of the server containing the JCO server configuration.
`transport.sap. enableErrorListener`	Set this to enable the default error listener. If this is used together with the `transport.sap.` `customErrorListener` parameter, the custom error listener will be used.
`transport.sap. enableTIDHandler`	Set this to enable the transaction handler to handle transactions that are received from a SAP system. Transactional applications must provide a custom implementation using the `transport.sap.` `customTIDHandler` parameter.
`transport.sap. customTIDHandler`	The fully qualified class name for the custom TID handler implementing `JCoServerTIDHandler`.
`transport.sap.connections`	The number of registered connections managed by the server instance. The default value is `1` and the maximum value is `100`.
`transport.sap. customErrorListener`	The fully qualified class name for the custom error listener implementing `JCoServerErrorListener`.
