The following sections describe the specifications supported by WebLogic Web Services:

SOAP 1.1 Specification

Simple Object Access Protocol (SOAP) is a lightweight XML-based protocol for exchanging information in a decentralized, distributed environment. The protocol consists of three parts: an envelope that contains a message, a description of the message, and how to process it; a set of encoding rules for expressing instances of application-defined data types; and a convention for representing remote procedure calls and responses.

The SOAP 1.1 specification is available at http://www.w3.org/TR/SOAP.

SOAP Messages With Attachments Specification

A SOAP message may need to reference an attached file, often in binary format, such as an image or spreadsheet file. The SOAP Messages with Attachments specification describes a standard way to associate a SOAP message with one or more attachments in their native format in a multipart MIME structure for transport.

Note: WebLogic Web Services currently ignore the actual attachment of a SOAP with attachments message.

The SOAP Messages with Attachment specification is available at http://www.w3.org/TR/SOAP-attachments.

Web Services Description Language (WSDL) 1.1 Specification

WSDL is an XML-based language that describes Web services. WSDL defines Web services as a set of endpoints operating on messages; these message contain either message-style or RPC-style information. The operations and messages are described abstractly in WSDL, and then bound to a concrete network protocol and message format to define an endpoint. Related concrete endpoints are combined into abstract endpoints (services). WSDL is extensible to allow the description of endpoints and their associated messages regardless of what message formats or network protocols are used to communicate, however, the only bindings described in the specification describe how to use WSDL in conjunction with SOAP 1.1, HTTP GET/POST, and MIME.

Note: WebLogic Server supports only SOAP 1.1 bindings.

The WSDL 1.1 Specification is available at http://www.w3.org/TR/wsdl.
