Soap. 40.3 The City has the right to inspect locker facilities and any City assets at any time upon reasonable suspicion that the employee has engaged in workplace misconduct. The City will be financially responsible for reimbursing an employee for loss or destruction of property by an agent or employee of the City during said inspection, excluding the locking device if the employee was given the opportunity to open said locker.
Soap. SOAP (Simple Object Access Protocol) is a XML-based communication protocol for accessing a web service, created to communicate over HTTP (which is today supported by all internet browsers and services). SOAP is platform and language independent, simple and extensible. SOAP may also be used over HTTPS (which is the same protocol as HTTP at the application level, but uses an encrypted transport protocol underneath) with either simple or mutual authentication. A SOAP message is an XML document containing: • an Envelope element that identifies the XML document as a SOAP message and constitutes the root element; it contains the namespace attribute (which defines the envelope as a SOAP envelope) and the encodingStyle attribute (defining the data types used in the document); • an optional Header element, containing application-specific information (like authentication, payment, etc) about the SOAP message; • a Body element, that contains the actual SOAP message (call and response information); • an optional Fault element containing errors and status information; it must be a child of the Body element and it can appear only once in a SOAP message. Although using SOAP over HTTP allows for easier communication through proxies and firewalls than previous remote execution technology, the technique has the disadvantage of using an application level protocol (HTTP) as a transport protocol (critics have argued that abusing a protocol by using it in a different purpose may conduct in sub-optimal behaviour). The following table shows a short summary of the advantages and disadvantages of SOAP protocol. Table 2: Pros and Cons of SOAP Pros and Cons SOAP Pros Cons Language, platform, and transport independent Conceptually more difficult, more "heavy- weight" than REST Designed to handle distributed computing environments More verbose Is the prevailing standard for web services, and hence has better support from other standards (WSDL, WS-*) and tooling from vendors Harder to develop, requires tools Built-in error handling (faults) Extensibility As seen in [Butek 2005]7 the binding style (affects the way in which the body of a SOAP message is constructed) can be “RPC or Document”. A SOAP binding can also have an encoded use or a literal use. Table 3 aims to summarize the different possibilities. Table 3: SOAP WSDL binding style/use Binding Style Affects the way in which the body of a SOAP message is constructed. RPC: Remote procedure call. Needs to comply with conventions. Docu...
