我对 Java 很陌生，并且在 dotnet 方面有一些经验。意图是在 java (jdk 1.6) 中创建一个 Web 服务并通过 dotnet 使用它。请假设我是 Java 的初学者。

我坚持使用 Java 创建 Web 服务（我是新手）.. 这是我的程序（样本取自net）

package example;
import javax.jws.WebService;
import javax.jws.WebService;
import javax.xml.ws.Endpoint;
@WebService
public class Calculator {
 @WebMethod(action="addNumbers")
   public int Add(int number1, int number2) {
        return number1 + number2;
    }
}
public static void main(String[] args) 
{         
 Calculator  server = new Calculator ();         
 Endpoint endpoint = Endpoint.publish("http://localhost:8080/AddWebService", server); 
}

所以在创建这个之后，我将它保存为 C:\Program Files\Java\jdk1.6.0\bin中的 Calculator.java

然后首先我编译为

apt -d 示例/Calculator.java

接着

java -cp example.Calculator

然后我尝试以http://localhost:8080/AddWebService?wsdl的身份访问 wsdl 文件， 但没有结果......请您帮我看看我做错了什么......

编辑

在我跑得恰到好处之后

-d example/Calculator.java

我在控制台中得到了以下信息

warning: The apt tool and its associated API are planned to be
removed in the next major JDK release.  These features have been
superseded by javac and the standardized annotation processing API,
javax.annotation.processing and javax.lang.model.  Users are
recommended to migrate to the annotation processing features of
javac; see the javac man page for more information.
Usage: apt <apt and javac options> <source files>
where apt options include:
  -classpath <path>          Specify where to find user class files and annotati
on processor factories
  -cp <path>                 Specify where to find user class files and annotati
on processor factories
  -d <path>                  Specify where to place processor and javac generate

  -factorypath <path>        Specify where to find annotation processor factorie
s
  -factory <class>           Name of AnnotationProcessorFactory to use; bypasses
 default discovery process
See javac -help for information on javac options.

在我跑了之后

java -cp example.Calculator

我在控制台中收到了以下内容

Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)
where options include:
    -d32          use a 32-bit data model if available
    -d64          use a 64-bit data model if available
    -client       to select the "client" VM
    -server       to select the "server" VM
    -hotspot      is a synonym for the "client" VM  [deprecated]
                  The default VM is client.

    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
                  A ; separated list of directories, JAR archives,
                  and ZIP archives to search for class files.

    -version      print product version and exit
    -version:<value>
                  require the specified version to run
    -showversion  print product version and continue
    -jre-restrict-search | -no-jre-restrict-search

    -agentlib:<libname>[=<options>]
                  load native agent library <libname>, e.g. -agentlib:hprof
                  see also, -agentlib:jdwp=help and -agentlib:hprof=help
    -agentpath:<pathname>[=<options>]
                  load native agent library by full pathname
    -javaagent:<jarpath>[=<options>]
                  load Java programming language agent, see java.lang.instrument

    -splash:<imagepath>
                  show splash screen with specified image
See http://java.sun.com/javase/reference for more details.

我不知道这是预期的行为还是其他什么。

非常感谢

对于最新的 Java 6，您不需要 apt 步骤。

此外，您的程序需要继续运行，否则它会在发布后立即关闭。

该错误是因为您有错误的 java 命令参数。您要运行的 java 命令将类似于，

java -cp . example.Calculator

注意 -cp 之后的 ,。

这是一个很好的 java入门页面
