这一个

  wb.getSettings（）setPluginState（WebSettings.PluginState.ON）。

A WSDL service description provides all the information that is required to use a web

WSDL.
<h4>OU demo services</h4></h4>
<p>At the OU there is a small set of toy web services. These can be accessed using a

Replace this line

  wb.getSettings().setPluginState(PluginState.ON);

with this one

  wb.getSettings().setPluginState(WebSettings.PluginState.ON);
