Question

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，一切都很好。但如果我工作几分钟......就像编辑一个jsp ...... Tomcat会对以下内容进行调整......

它抱怨丢失的标签是页面布局的标签。没有其他令人兴奋的东西，除了它有一些jspf包括和内容页面也称为其他标签。但同样，没有什么令人兴奋的......

我没有看到我是如何导致这一点的，因为事情编译并且最初运行良好。但是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......

有什么想法吗？感谢

Answer 1

尝试以下任何一项，它应该可行

复制WEB-INF/lib/目录中的jar，然后重新启动Web容器

尝试

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

例如

    <%@ page language="java" import="org.apache.jsp.tag.webrating" %>

清理项目并重新启动服务器

Eclipse / Tomcat忘记了自定义标签？
