title: How to generate client code using wsdl2java through https?
body: <p>I'm using Tomcat 6 and CXF 3 to implement some web services. I need to generate client code by using wsdl2java command on my local server. And it works on http protocol: </p>
  
  <pre><code>wsdl2java -frontend jaxws21 -p com.activenetwork.iam.ws.client -d "D:\devtools\workspace\TestClient\src" -encoding utf-8 -client -V http://localhost:8080/IAM/services/employee?wsdl
  </code></pre>
  
  <p>But, after i updated the server to https protocal, the command doesn't work anymore</p>
  
  <pre><code>wsdl2java -frontend jaxws21 -p com.activenetwork.iam.ws.client -d "D:\devtools\workspace\TestClient\src" -encoding utf-8 -client -V https://localhost:8443/IAM/services/employee?wsdl
  </code></pre>
  
  <p>I got below error:</p>
  
  <pre><code>Loading FrontEnd jaxws21 ...
  Loading DataBinding jaxb ...
  wsdl2java -frontend jaxws21 -p com.activenetwork.iam.ws.client -d D:\devtools\workspace\TestClient\src -encoding utf-8 -client -V https://localhost:8443/IAM/services/employee?wsdl

  <p>It looks this is a certificate problem. I'm not familiar with this, can someone point me out how to solve this problem?</p>
