SOAP with Attachments

In this use case, the binary attachments (for instance, an image) are passed end-to-end as a stream. Table 52-5 provides details.

Table 52-5 Capabilities

Capability Description

Security

Not supported.

Filter/Transformation/Assign

Pass through. You must use an XPath extension function in Oracle BPEL Process Manager.

Binding

WS binding creates stream iterators for the SOAP attachment.

Oracle BPEL Process Manager/Oracle Mediator

Oracle Mediator can perform a pass through without materializing it. Oracle BPEL Process Manager persists it.

Tuning

Manage the database tablespace when using with Oracle BPEL Process Manager.

WSDL code for defining SOAP with attachments

 
<mime:part>
   <mime:content part="bin" type=“image/jpeg"/>
</mime:part>

Note:

  • You cannot stream attachments as part of a web service callback response.

  • The spring service component does not support processing MIME attachments. Only MTOM attachments are supported.

  • You can use various binding components such as direct binding, web services, and so on to process large attachments. However, processing large attachments with direct binding is not recommended and results in out-of-memory errors.
