我在 Windows 7 64 位上使用 Eclipse Kepler 和 Tomcat 7。

如果我清理项目并重新启动服务器，一切正常。但是如果我工作几分钟......就像编辑一个jsp......Tomcat会抛出以下......

它抱怨缺少的标签是页面布局的标签。除了包含一些 jspf 并且内容页面还调用其他标签之外，没有什么令人兴奋的了。但同样，没有什么令人兴奋的......

我不明白我是如何造成这种情况的，因为事情最初编译并运行良好。但随后 Tomcat 似乎忘记了标记类。

如果我清理项目，它会恢复工作一段时间......

有任何想法吗？谢谢

尝试以下任何一种，它应该工作

  1. 将 jar 复制到WEB-INF/lib/目录中，然后重新启动您的 Web 容器

  2. 尝试

    <%@ page language="java" import="Pkgname.className.*" %>

例如

    <%@ page language="java" import="org.apache.jsp.tag.webrating" %>
  1. 清理项目并重启服务器
