運行從wsdl2java生成的webservice cxf

Question

我試圖運行使用cxf從wsdl生成的webservice。

1. 獲取樣本WSDL（hello_world.wsdl）
   • http://cxf.apache.org/docs/developing-a-consumer.html
2. 生成WSDL從Java代碼
   • '的WSDL2Java -ant -server -d服務器hello_world.wsdl'
   • http://cxf.apache.org/docs/wsdl-to-java.html
3. 由於服務執行力度在生成的代碼丟失，我從這裏
   • http://alvinalexander.com/java/jwarehouse/apache-cxf/distribution/src/main/release/samples/configuration_interceptor/src/demo/stream/server/GreeterImpl.java.shtml
   • 更改包名稱正確了GreeterImpl。
4. 'ant compile'成功。
5. 'ant GreeterServer'不成功。

我錯過了什麼？

不知道什麼會導致此。看起來不知何故，你的JVM從System.getProperties（）。propertyNames（）返回一個空屬性名稱。在此之前調用到CXF代碼，你可以嘗試這樣的：

@SuppressWarnings("unchecked") 
Enumeration<String> systemKeyEnum = (Enumeration<String>)System.getProperties().propertyNames(); 
while (systemKeyEnum.hasMoreElements()) { 
    String key = systemKeyEnum.nextElement(); 
    String val = System.getProperty(key); 
    System.out.println(key + ": " + val); 
} 

，看是否實際工作？
