java.lang.NoClassDefFoundError： org/apache/commons/discovery/tools/DiscoverSingleton
我已经使用jsf在jsp文件中创建了一个注册表，并尝试将其与Web服务连接，以便将元素传递到数据库。
当我按下提交按钮时，我收到一个错误。我不认为问题与连接代码有关，但我不确定。
谁能告诉我一些可能以某种方式帮助我的事情？
错误：
javax.servlet.ServletException: #{formabean.submitdetails}: java.lang.NoClassDefFoundError: org/apache/commons/discovery/tools/DiscoverSingleton
javax.faces.webapp.FacesServlet.service(FacesServlet.java:256)
org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:390)
我的表单 jsp：
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

我的豆类“formavar”：
package org.forma;
import org.imigrant.Migration.MigrationResult;
import org.imigrant.Migration.MigrationWS_PortType;
import org.imigrant.Migration.MigrationWS_Service;
import org.imigrant.Migration.MigrationWS_ServiceLocator;
/** libraries for Web Service*/
/**
*
* @author USER
*/
public class formavar {
private String name;
private String lastname;.....
public String getName() {
return name;
}
/**
* @param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* @return the surname
*/
public String getLastname() {
return lastname;
}
/**
* @param surname the surname to set
*/
public void setLastname(String lastname) {
this.lastname = lastname;
}......
public String submitdetails() {
String migrationURL = "http://localhost:8080/mule-tomcat/ESB/Migration?wsdl";
MigrationResult registrationResult = new MigrationResult();
try {
MigrationWS_Service service = new MigrationWS_ServiceLocator(migrationURL);
MigrationWS_PortType port = service.getMigrationImplPort();
registrationResult = port.registerDoc(
null,
this.granting,
this.expire_date,
this.name,
this.lastname,.............
);
return "OK";
} catch (Exception ex) {
return "ERROR "+ex.getMessage();
}
//return "OK";
}
}
和配置 xml：
<managed-bean>
<managed-bean-name>formabean</managed-bean-name>
<managed-bean-class>org.forma.formavar</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
