Answer 1

java.lang.ClassNotFoundException: com.nantian.test.impl.UserDaoImpl
错误内容很清晰，找不到类文件。估计打包或发布的时候，漏了这个类，自己检查下吧。

Answer 2

是要看web.xml 还是导入的包有问题啊？
web.xml：

Answer 3

是你的 WEB-INF\classes 目录中，有没有 com\nantian\test\impl\UserDaoImpl 这个类的问题。

Answer 4

不能生成.class文件，怎么办？

Answer 5

你的开发环境是不是配置出问题了？class编译文件都没生成？或者你的发布就配置错了。

Answer 6

<context-param>
  <param-name>ContextConfigLocation</param-name>
  <param-value>classpath:WEB-INF/application-*.xml</param-value>
 </context-param>是不是少了classpath: ?? 像我写的那样？？

Answer 7

WEB-INF\classes 目录中，没有 com\nantian\test\impl\UserDaoImpl 这个类，怎么改？

Answer 8

.class文件：
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/jre6">
<attributes>
<attribute name="owner.project.facets" value="jst.java"/>
</attributes>
</classpathentry>
<classpathentry kind="con" path="org.eclipse.jst.server.core.container/org.eclipse.jst.server.tomcat.runtimeTarget/Apache Tomcat v6.0">
<attributes>
<attribute name="owner.project.facets" value="jst.web"/>
</attributes>
</classpathentry>
<classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.web.container"/>
<classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.module.container"/>
<classpathentry kind="output" path="build/classes"/>
</classpath>
是哪里错了呢？

Answer 9

<classpathentry kind="output" path="build/classes"/>
尝试修改下，输出到
<classpathentry kind="output" path="WEB-INF/classes"/>不过总感觉你的配置很奇怪，你在Eclipse中新建工程的时候，真的用的是J2EE工程么？

Answer 10

还是出现java.lang.ClassNotFoundException: com.nantian.test.impl.UserDaoImpl
类没找到，是数据库没连上吗？
