WSO2治理注册表-正在添加服务通知

Question

我按照链接中列出的示例添加自定义电子邮件通知。

在我的maven项目"RegistryService"中：我创建了EmailTransformHandler，并使用maven创建了RegisterService-0.1.jar。我还通过添加处理程序修改了GREG_HOME/repository/conf/axis2/axis2.xml：

<handler name="EmailTransformHandler"
                 class="com.registration.example.service.EmailTransformHandler"/>

并在GREG_HOME/repository/components/dropins 中丢弃RegistryService-0.1.jar

package com.registration.example.service;
import java.util.ArrayList;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.xpath.AXIOMXPath;
import org.apache.axiom.soap.SOAPEnvelope;
import org.apache.axis2.AxisFault;
import org.apache.axis2.context.MessageContext;
import org.apache.axis2.engine.Handler;
import org.apache.axis2.handlers.AbstractHandler;
public class EmailTransformHandler extends AbstractHandler implements Handler {
    private String name;
    public String getName() {
        return name;
    }
    @Override
    public InvocationResponse invoke(MessageContext msgContext) throws AxisFault {
        if (msgContext.getTo() != null && msgContext.getTo().getAddress().startsWith("mailto:")) {
            try {
                SOAPEnvelope env = msgContext.getEnvelope();
                AXIOMXPath xPath = new AXIOMXPath("//ns:text");
                xPath.addNamespace("ns", "registry_example");
                OMElement element = (OMElement) ((ArrayList) xPath.evaluate(env)).get(0);
                element.setText(element.getText().replace("--", "This message intercepted by Terminator"));
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return InvocationResponse.CONTINUE;
    }
}

当我转到GREG_HOME/bin并启动服务器时，我得到以下异常：

我缺少什么配置？在谷歌上搜索这个错误并没有产生任何相关的结果（除了一些对我帮助不大的俄罗斯论坛）。我甚至尝试通过WSO2管理控制台添加jar作为扩展，但我仍然遇到了这个异常。

根据错误，您的RegistryService-0.1.jar没有正确设置为类路径。如果jar文件不是OSGI捆绑包，那么该jar文件应该放在"GREG_HOME/repository/components/lib"目录中。
