问题 The most useful thing I like about SOAP vs REST is the WSDL. It makes my life much easier when creating applications for the iPhone as my classes can be generated for me without me doing much monkey work. However, I'm trying to find a suitable alternative to ASMX/WCF. I predominantly use a Mac so Java, PHP or Mono solutions are mainly of interest to me. I understand PHP has a SOAP service offering but it can't automatically generate a WSDL? Are there any tools which can facilitate this? 回答1:

问题 I'm using Oracle BPEL 12c to develop a process. I need to call a external service with basic authentication. I need to pass the credentials received on my exposed service endpoint to the external service. When i call, i receive this: <remoteFault xmlns="http://schemas.oracle.com/bpel/extension"> -<part name="summary"> <summary> oracle.fabric.common.FabricException: oracle.fabric.common.FabricException: Error in getting XML input stream:XXXXXX?WSDL: Server Authentication Required: Error in

问题 I'm am trying to figure out how the Oracle "Layered Architecture Model" works, and I am very confused about what the business, data, and presentation do, and how they relate to each other. I have seen many diagrams showing how this should work, but some real world examples would be useful? For example I am guessing that web applications are what Oracle calls "Composite applications" and that these web applications are built up of what Oracle calls "Presentation Services". 回答1: Let me try to

问题 I am thinking of building an application using a Service Oriented Architecture (SOA). This architecture is not as complex and messy as a microservices solution (I think), but I am facing similar design problems. Imagine I have services of type ServiceA that send work to services of type ServiceB. I guess, if I use a queue, then load balancing will not be a problem (since consumers will take what they can handle from the queue). But queues tend to generate some bad asynchrony in the code that

问题 I am creating a process in BPEL (say findRules) which has three Java Embeded Activity(A,B,C). and I have one java class(Rule.java) which I need to import on all Java Embed Activity. and when I create an instance of Rule.java A activity, can I use the same instance in B and C activity. because I am performing some business logic in A and wanted to access the updated varibles in B and C. but because B and C are having new instance I am not able to find those updated variables. 回答1: If you are

问题 Let's consider I need to develop a REST bank application that allows the creation/destruction of bank accounts as well as the following operations on an account: withdraw/credit/getBalance. Creation of an account PUT /Bank/john Here I use PUT instead of POST because this operation is idempotent and because the client is giving the URL Destruction of an account DELETE /Bank/john GetBalance GET /Bank/john Withdraw money from an account POST /Bank/john action=withdraw&value=10 Credit money to an

问题 I have some confusion regarding the reference architecture provided by The Open Group for SOA that can be used as an example for enterprises. Question 1: Within this reference architecture there is the service layer which exposes a service to the outside world. The standards document says that you can have process services within this service layer, which implements some process of functionality that can be accessed as a service. It is also possible to have composed services in the service

问题 Truth be told I have no clue whether SOA describes/recommends which protocols web services should use for interoperability, or whether it also defines some of the protocols, or does it just recommend the design patterns and best practices services should follow in order to achieve interoperability Anyways, are SOAP, WSDL and WS-* specifications part of SOA and thus outside of SOA arhitecture we use other means to achieve interoperability between web services, or can/are they used

问题 I'm in the process of designing the base architecture of a web application. The project follows the Domain-Driven Design approach because the business model and logic is very complex. The project also aims to be a SOA project (Service Oriented Architecture). So I'm learning a lot about Services and how to construct the project around it. Following a previous question of mine, I have a question regarding associations in model classes . I understand that model classes shouldn't know and do

问题 I read a lot of integration literature that talk about the evolution of integration architecture from Point-to-Point to Hub-Spoke to ESB. But for the life of me I am struggling to understand the difference between Hub-Spoke and ESB. Hub and Spoke is usually depicted as the following - Hub as one big circle (Hub) with multiple smaller circles around connected to the hub via spokes But the same can redrawn as you would depict an ESB right? So I am not sure why ESB and Hub-Spoke architectures
