I am most busy studying a Java open-source project. This open-source project is based on the SOA architecture, and all the services provided need to be accessed by the. NET client. I always thought that the Web service is not only a little performance problem, but it is omnipotent. After this training, I finally understood that the world is not as perfect as I imagined... Okay, let's get started. This document describes how to access platform-specific objects on heterogeneous platforms through Web Services. The following is a summary of this study.
The W3C XML Schema standard defines a series of built-in data types, including various types of strings of different lengths, integer, Boolean, single precision, double precision, floating point, time type, and other types. Each application platform supports a series of its own data types. The intersection of these data types defines types with collaboration capabilities across different platforms. Therefore, A. Net client can recognize XML elements as record sets, which does not mean that a Web service client written in Java can do the same thing.
First, let's talk about the Web Service Development Method: 1.Execution priority"Or"Code first", That is, to start with the code to complete the function, first develop the interface function, and then rely on the. Net or Java WSDL framework to generate the WSDL description file. Disadvantage: some non-public types are difficult to map to heterogeneous platforms. 2 ."WSDL Priority"Or"Mode first", That is, start with the WSDL file, first build the WSDL file, and then develop and implement the web service and client. This increases the possibility of cross-platform data types to a certain extent.
To develop a. NET web service, we must realize that the asmx file is a real web service. The page you see is derived from the framework. It is used to prove Web Services and allows developers to test web services without manually creating client applications. This function is only used to browse local pages and is unavailable when you enter a complex data type as a parameter to Web Services.
Run the following command to run wsdl.exe to generate the Web Service source code file.

Soap messages can have one of two encoding styles:
