1. How to monitor SOAP requests and response streams
The presenter we did is very simple, the method's parameters and return values are simple type data, but in actual
It is often not so simple during the application. When using an object-oriented programming language, we will want the data type but
An object, such as we provide an interface to query city information, then we want the interface to the interface is a city
City information object, this information object encapsulates the needs of a city information, including the name, region
Zip code, area code, population. Area information, etc. If we make each content into a parameter, the parameters of this interface may be very much. Therefore, it is necessary to encapsulate objects.
The processing of complex type data is also very simple when using AXIS to write a Web service. AXIS requires complex
The writing of a miscellaneous object must comply with JavaBean's specifications, simply that the object's properties are passed
Getter / setter method is accessible. Take a look at the WSDL information output by the simple example below.

Let's take a look at the change of querycity.wsdl.
The red part has obvious changes, and it can understand what changes can be understood more than before.
The two types of cityinfo and disposequerycity are defined here, which is the parameter type and return of our interface.
