大家好，我最近在WebLogic 14.1.2、Ant 1.10.15（注：原描述写的1.0.15，推测是笔误）和JDK17环境下搭建JAXWS示例服务，执行jwsc Ant任务时遭遇了失败。我已经尝试通过设置ANT_OPTS和JAVA_TOOL_OPTIONS来配置模块访问权限，但问题依然存在，希望社区的朋友们能帮我排查下问题。

1. 服务实现类代码 #

package examples.webservices.hello_world;

import javax.jws.WebService;

@WebService(name="HelloWorldPortType", serviceName="HelloWorldService")
public class HelloWorldImpl {
    public String sayHelloWorld(String message) {
        try {
            // System.out.println("sayHelloWorld:" + message);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return "Here is the message: '" + message + "'";
    }
}

2. build.xml配置 #

<project name="webservices-hello_world" default="all">
  <property name="WL_HOME" value="D:\Install\Oracle_Home_14_1_2\Oracel_Home\wlserver"/>
  <path id="weblogic.ant.classpath">
    <pathelement location="${WL_HOME}/server/lib/weblogic.jar"/>
    <pathelement location="${WL_HOME}/server/lib/wlthint3client.jar"/>
  </path>
  <taskdef name="jwsc" classname="weblogic.wsee.tools.anttasks.JwscTask">
    <classpath refid="weblogic.ant.classpath"/>
  </taskdef>
  <target name="build-service">
    <jwsc srcdir="src" destdir="${ear-dir}" >
      <jws file="examples/webservices/hello_world/HelloWorldImpl.java" type="JAXWS">
      </jws>
    </jwsc>
  </target>
</project>

3. 报错堆栈信息 #

我已经尝试过的操作 #

• 配置ANT_OPTS参数，添加了JDK17模块化相关的参数，比如--add-modules java.se、--add-exports java.base/jdk.internal.reflect=ALL-UNNAMED等
• 配置JAVA_TOOL_OPTIONS参数，内容和ANT_OPTS类似
• 确认了WebLogic的类路径配置正确，weblogic.jar和wlthint3client.jar的路径都没问题

但以上操作都没能解决问题，有没有朋友遇到过类似的情况？或者能从报错堆栈里看出问题所在吗？
