WSDL2Java证书错误

Question

使用Apache Axis2中包含的WSDL2Java.bat从在线SOAP WSDL服务生成.java文件，但是我得到了一个关于某些证书的错误。我不知道这是从哪里来的，它应该按照我得到的指令工作。

Using JAVA_HOME:    C:\Program Files\Java\jre7

有没有人知道这个问题是什么，或者我应该从哪里开始寻找？

谢谢

您似乎正在尝试从HTTPS URL使用WSDL生成Java类。它在尝试验证证书时失败。

尝试从浏览器访问WSDL，它应该会给您一个警告。

您可以将WSDL保存到本地目录，并尝试对该文件运行WSDL2Java。

但是，如果端点也是HTTPS URL，则通过存根访问web服务时可能会出现类似的错误。
