Question

我正在尝试将maven生成的war文件部署到eclipse中的tomcat服务器中..但是我在jar文件中得到了java.lang.NoClassDefFoundError。我多次验证，jar在.war中，jar中也有相应的类文件。我可以在eclipse中从生成的位置复制战争并成功部署到tomcat的webapps中（使用与eclipse中安装的服务器相同的服务器）。

除了部署程序集（已列出jar）和Java Build路径（jar在Maven依赖项中可用）之外，我不确定还要检查其他配置。我正在使用JRE - ＆gt;备用JRE指向JDK 1.6

完成错误日志：

使用服务器实例与在tomcat中部署WAR不同。服务器视图集成tomcat'hot'部署源文件夹。我建议您检查Java构建路径设置，因为在将服务器项目部署到服务器视图中的服务器时会使用这些设置。你是如何创造战争的？我假设你正在使用maven ..如果你使用maven（我个人不喜欢它），它应该为你管理依赖。您可能必须在java中复制maven的设置，或者可能使用maven插件进行eclipse。 [http://www.eclipse.org/m2e/]

eclipse和tomcat中的java.lang.NoClassDefFoundError但是WAR在独立的tomcat中工作
