问Web Axis2客户端代码生成问题

EN

我正在尝试使用使用Axis2构建的web服务，因此我遵循了这个例子来创建客户端代码。

我有端点，我可以通过浏览器访问它。但是，尝试使用以下方法生成客户端代码：

WSDL2Java.bat -uri <<endpoint>> -o client

引发以下异常：

线程“主”org.apache.axis2.wsdl.codegen.CodeGenerationException:错误解析WSDL at org.apache.axis2.wsdl.codegen.CodeGenerationEngine.(CodeGenerationEngine.java:181) at org.apache.axis2.wsdl.WSDL2Code.main(WSDL2Code.java:35) at org.apache.axis2.wsdl.WSDL2Java.main(WSDL2Java.java:24)引起的异常: java.net.ConnectException:连接超时:连接在java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:213) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:200) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connectcom.sun.net.ssl.internal.ssl.SSLSocketImpl.connect(SSLSocketImpl.java:570) at com.sun.net.ssl.internal.ssl.BaseSSLSocketImpl.connect(BaseSSLSocketImpl.java:141) at sun.net.NetworkClient.doConnect(NetworkClient.java:163) at sun.net.www.http.HttpClient.openServer(HttpClient.java:411)在sun.net.www.http.HttpClient.openServer(HttpClient.java:525) at sun.net.www.protocol.https.HttpsClient.(HttpsClient.java:272) at sun.net.www.protocol.https.HttpsClient.New(HttpsClient.java:329) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.getNewHttpClient(AbstractDelegateHttpsURLConnection.java:172) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:923) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:158) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1195) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:379) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(HttpsURLConnectionImpl.java:318)在org.apache.axis2.wsdl.codegen.CodeGenerationEngine.(CodeGenerationEngine.java:99) .还有两个

造成这一错误的原因是什么？
