为什么在Web服务中使用complexType？

Question

I just read a book about web servieces at it says there is "RPC style web service" and "Document style web service". the second is using in WSDL sequence and complexType. When should I use this style?

Answer 1

complexType in webservice will be used to represent user defined data types like Objects you want to transfer (not java default types), for example if you have UserVO which contains name, address, phone etc.,, you need to define this as ComplexType in WSDL to send. Java collections/array also treated as complex types. Here is good tutorial on Types of Webserices and example complex type.
