求解,axis webservice 异常
完全按照下面教程中的步骤做的:rn1.即时发布 JWS (Java Web Service) Files - InstantrnDeploymentrn即时发布提供了一种非常简单发布方式,发布者只要有Java 源代码(也就是.java 文件),rn然后把其后缀名改成jws ( 也就是 java web service 的缩写) 拷贝到rn%TOMCAT_HOME%\webapps\axis 目录下即完成了所有的发布工作。AXIS 的编译引擎会处rn理接下来的所有事情。下面是一段示例代码:rnjava 代码rnpublic class HelloAXIS rnpublic String Hello(String name)rnreturn "AXIS say hello to " + name;rnrnrn把 HelloAXIS.java 文件改成 HelloAXIS.jws 然后拷贝到rn%TOMCAT_HOME%\webapps\axis 目录下, 启动Tomcat 之后访问rnhttp://localhost:8080/axis/HelloAXIS.jws 如果能看到 Click to see the WSDL 这个超链接就说rn明已经发布成功了,点击进去就可以看到这个Webservice 的WSDL 描述文件。server 端的rn发布已经完成了,接下来就是编写Client 端测试代码了。rnjava 代码rnpackage com.chnic.test;rnimport java.net.URL;rnimport javax.xml.namespace.QName;rnimport org.apache.axis.client.Call;rnimport org.apache.axis.client.Service;rnpublic class Test rnpublic static void main(String[] args) throws ExceptionrnString targetEendPoint = "http://localhost:8080/axis/HelloAXIS.jws";rnService service = new Service();rnCall call = (Call) service.createCall();rncall.setOperationName(new QName(targetEendPoint, "Hello"));rncall.setTargetEndpointAddress(new URL(targetEendPoint));rnString result = (String) call.invoke(new Object[]"Robert");rnSystem.out.println(result);rnrnrn测试代码很简单,如果熟悉java 反射机制的朋友不用两分钟就能看明白。运行后客rn户端控制台出现 AXIS say hello Robert。测试成功。果然很简单吧。不过在这简单背后却是rn以牺牲灵活性为代价的。假如你现在手里只有.class 或者一个jar 包,jws 就不再能满足你的rn需求了,最要命的就是即时发布不支持带包的类,这点AXIS 的用户手册上写的也很明白。rnrn执行Test.jav的时候出现如下<em>异常</em>:rnException in thread "main" AxisFaultrn faultCode: http://schemas.xmlsoap.org/soap/envelope/Server.userExceptionrn faultSubcode: rn faultString: java.net.SocketException: Network is unreachable: connectrn faultActor: rn faultNode: rn faultDetail: rnrnTOMCAT已经启动,url可以通过浏览器访问,可是为什么在执行客户端的时候报出:java.net.SocketException: Network is unreachable: connect呢?rnrngoogle没能解决,baidu也没能解决。
