How to generate java client classes from WSDL file using wsimport. Parameters used p, s wsdllocation and verbose.
WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. WSDL stands for Web Services Description Language. The WSDL is an abstract definitions of ports and messages, being separated from the concrete implementation. Using this model to define the service allows the reuse of these definitions and also will allow to implement server and client independently.
In a application you can have resources that are limited or time consuming to create a new one. e.g. a connection to a database, a new thread. A solution is to create a the limited resource once and reuse it. To address this problem the object pool pattern was introduced. The object pool design will have the mechanism to create a new object to keep the objects and to destroy the objects if necessary.
A design pattern is a general solution to a common problem. The singleton pattern is used to restricts the instantiation of a class to one single object.
