Tibco BW and SalesForce

You can access SalesForce integration API without dedicated adapter, just modify SF WSDL file:

<complexType name="sObject">
  <sequence>
    <element maxOccurs="unbounded" minOccurs="0" name="fieldsToNull" nillable="true" type="xsd:string"/>
    <element name="Id" nillable="true" type="tns:ID"/>
  </sequence>
  <attribute name="xsi:type" type="xsd:string"/>
</complexType>

<element name="upsert">
  <complexType>
    <sequence>
      <element name="externalIDFieldName" type="xsd:string"/>
      <element maxOccurs="unbounded" minOccurs="0" name="sObjects" type="xsd:anyType"/>
    </sequence>
  </complexType>
</element>

add manually namespace and prefix to BW process and fill @type attribute.
