生成 wsdl 时出现 Axis2 错误

Question

我正在尝试使用 JAX-WS 和 JAXB 注释开发新的 Web 服务。 当我在axis2中部署.jar并打开浏览器以检索生成的.wsdl时，出现以下错误：

[ERROR] Error occurred generating WSDL file for Web service implementation class {foo.bar.myServiceImpl}

挖掘源代码，我注意到 com.sun.xml.ws.api.server.Container 是 jaxws-rt 实现的一部分，它不是 Axis2 发行版的一部分（在 / lib/ 文件夹）。为什么是这样？我在这里漏掉了一点吗？

我遇到了同样的问题。我需要向 jaxws-maven-plugin 添加依赖项。没有这些依赖，它会抛出同样的错误

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>jaxws-maven-plugin</artifactId>
            <configuration>
                <wsdlDirectory>src/main/resources/wsdl/</wsdlDirectory>
                <keep>true</keep>
                <sourceDestDir>${project.build.directory}/generated-sources/wsimport</sourceDestDir>
                <sei></sei>
            </configuration>
            <dependencies>
                <dependency>

                    <version>2.1.4</version>

好的，知道了。 我会发布答案以避免其他人将他（或她）的头撞到墙上。

我的系统上设置了旧的 JAVA_HOME 环境变量。这指向安装程序 JRE，但它需要指向已安装的 JDK。就是这样。
