<proxy name=”sapbapiproxy” transports=”bapi”/>
//in,out,fault Sequence
  <parameter name="transport.sap.serverName">JCOSERVER01</parameter>
// other parameters
</proxy>

SAP endpoint server property file should be in <ESB_HOME>/repository/conf/sap/JCOS ERVER01.server

IDoc adapter

Code Block

language	html/xml

<endpoint name="sapidocendpoint">
   <address uri="idoc:/JCOCLIENT01"/>
</endpoint>

The SAP endpoint client property file should be in <ESB_HOME>/repository/conf/sap/JCOCLIENT01.dest

Code Block

language	html/xml

<proxy name=”sapidocproxy”transports=”idoc”/>
//in,out,fault Sequence

SAP endpoint server property file should be in <ESB_HOME>/repository/conf/sap/JCOSERVER01.server

Following are descriptions of the proxy level listener parameters that can be defined in a proxy configuration:

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`.
`transport.sap.` `customExceptionListener`	The fully qualified class name for the custom exception listener implementing `JCoServerExceptionListener`.

Following are descriptions of the SAP client properties that can be defined in the message context with axis2-client scope:

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 is an Axis2 transport sender property that can be defined in axis2.xml:

transport.sap.customXMLMappers : The key/value list of custom mappers, where the values are fully qualified class names for custom mappers implementing org.wso2.carbon.transports.sap.idoc.IDocXMLMapper.
