Eclipse，使用Web服务会给出java.lang.reflect.InvocationTargetException

Question

想要一些帮助。 我已经花了很多时间尝试解决这个问题，在网络中搜索某些网站-这里有一些问题-但仍然没有答案。 任何帮助将不胜感激。

我并不是说这是专家，所以某些信息可能含糊不清，我将尝试使用最佳术语来描述问题。

当我尝试使用我自己使用Eclipse，Java语言，使用Apache Tomcat 6创建的Web服务时，出现一个错误：

正文内容无法在表单视图中显示。 请切换到源代码视图以检查原始内容。

我将Web服务（这11种方法）作为Java应用程序和JUnit测试进行了测试，这很好。 这些方法在MYSQL的数据库中删除，添加，修改和搜索某些信息。 正如我所说，这些方法可以作为Java应用程序正常运行。

我试图在其他项目上生成客户。 如果我尝试从客户端使用Web服务，它将给我以下错误：

我记得有人说这是因为我的主机名叫做“ Mauricio-PC”，而Tomcat无法识别它。 但是我真的不知道那是不是真的。

因此，非常感谢您的帮助。 随意问任何问题。

谢谢。

编辑：我创建了另一个名称为ServicioCapacitacion而不是SistemaCapacitacion的项目。 相同的文件。 我重新导入了.jars。

所以我有这个库：

Library Apache Tomcat v6.0:
  annotations-api.jar
  catalina-ant.jar
  catalina-ha.jar
  catalina-tribes.jar
  catalina.jar
  ecj-3.7.2.jar
  el-api.jar
  gson-2.2.3.jar
  jasper-el.jar
  jasper.jar
  jsp-api.jar
  mysql-connector-java-5.1.25-bin.jar
  orm.jar
  servlet-api.jar
  tomcat-coyote.jar
  tomcat-dbcp.jar
  tomcat-i18n-es.jar
  tomcat-i18n-fr.jar
  tomcat-i18n-ja.jar

JRE System Library:
  resources.jar
  rt.jar
  jsse.jar
  jce.jar
  charsets.jar
  jfr.jar
  access-bridge-64.jar
  dnsns.jar
  jaccess.jar
  localedata.jar
  sunec.jar
  sunjce_provider.jar
  sunmscapi.jar
  zipfs.jar

JUnit 4:

  junit.jar
  org.hamcrest.core_1.1.0.v20090501071000.jar

Web App Libraries:
  axis.jar
  commons-discovery-0.2.jar
  commons-logging.jar
  jaxrpc.jar
  saaj.jar
  wsdl4j.jar



gwt-dev.jar    <- These are alone, not inside any Library
gwt-servlet.jar
mail.jar

在目录WebContent> WEB-INF> lib中，有以下库：

axis.jar
commons-discovery-0.2.jar
commons-logging.jar
jaxrpc.jar
saaj.jar
wsdl4j.jar

我知道已经重复了这些库，我的问题是，是否必须删除其中一个组？ 我要消除/移动哪个组以及保持哪个组？ 有没有“好的”方法将其删除？

JSP文件：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Test JSP</title>
</head>
<body>
HI THERE!
<%= new servicio.Servicio().verActa("1", "1") %>
</body>
</html>

将其命名为index.jsp并将其添加到您的WebContent\\文件夹中。 确保没有其他名为index或default文件。
