Who knows how to use Java to make weather forecast, and can query the weather in their own websites?

People who make software don't like to invent repetitive wheels. The weather situation is solved by webservice technology. Through SOAP protocol, you must provide an interface and a wsdl file on the weather forecast project. If you want to realize it yourself, you must do such a function yourself. The advantage of webservice is to obtain the' behaviors' of different languages, because it transmits data through xml files.
