In most cases, it's best to access SOAP services in this manner, i.e., by using wsimport to generate
service‐wrapping classes and use those in your projects. One final remark concerns the fact that
the WSDL file will continue to be accessed by the generated classes every time you use them. To see
how, take a look at the generated StockQuote class and note the following lines:
static {
URL url = null;
WebServiceException e = null;
try {
