I'm having really big problem with running webapp on tomcat 7 from IntelliJ (Ultimate) IDE. The problem is, that I can't get working taglibs for my jsp. Doesn't really matter what kind of taglib I'm trying to add, it's not working anyway. The JSP only have taglibs:

<%@ page contentType="text/html;charset=UTF-8" language="java" %> 
<%@ taglib prefix="dec" uri="http://www.opensymphony.com/sitemesh/decorator" %> 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> 
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>

And the exception (for EVERY taglib):

23:50:22,420 ERROR UnhandledExceptionsFilter:34 - Unhandled exception:

Yet it's not working anyway. What's most interesting, is that when I copy the exact war generated into ../webapps directory in Tomcat, and run manually, it works. Any clue why it's not working from IDE?

我使用您的 POM 创建了一个 hello world webapp，并在我的 hello.jsp 页面上使用了 JSTL taglib。工作正常。我可以通过删除我的 POM 中的 jstl 依赖项并进行干净的构建和部署来重现您的问题。因此，当您通过 IDEA 运行 webapp 时，标签库 jar 似乎位于类路径中。由于它们在您的 POM 中进行了编译，因此它们应该是。或者更具体地说，它们应该在工件中。既然您提到您可以将战争复制到 Tomcat 并成功运行它，这让我相信当通过 IDEA 运行您的 web 应用程序时，它没有使用该工件（即战争文件）进行部署。在 IDEA 中创建一个 tomcat 运行/调试配置以使其部署爆炸的战争而不是战争文件本身的情况并不少见。这提供了能够即时更新资源的优势。

以下是您可以检查的一些事项：

进入你的 tomcat 运行/调试配置。在部署选项卡上，查看正在部署的工件。它应该是maven-module-name:war或maven-module-name:war exploded。如果没有，请将其更改为其中之一。如果是，请选择它并单击编辑图标。这将在Project Structure对话框中打开工件定义。如果是war 文件，它应该将归档定义显示为展开目录的war。选择（在中间窗格中）maven-module-name:war exploded人工制品。展开 WEB-INF/lib 目录。确保标签库 jars 显示在那里。如果没有，您可以尝试从 maven 工具窗口重新导入 maven 项目以使事情同步。您可能需要运行 2 到 3 次。（我曾经经历过一个必要的案例）。一旦工件被纠正，你应该很高兴。

如果工件没问题，请尝试对所有内容进行完全手动清理。IDEA 可能会认为罐子存在，但实际上它们不存在。当你启动 tomcat 时，在控制台输出中，你应该看到CATALINA_BASE设置为 IDEA 的配置目录中的一个目录。置顶 IDEA 后，去删除那个目录。然后删除该${CATALINA_HOME}/webapps目录（或至少您的应用程序目录和任何战争文件）。接下来删除 IDEA 正在构建的目标（或输出）目录。之后尝试通过 IDEA 启动 tomcat 实例。

如果 webapp 清理不起作用，请尝试使缓存无效File > Invalidate Caches，重新启动 IDEA，并让它重新索引项目。您可能希望再次将这个与完全清洁的 web 应用程序结合起来。

如果这些都不起作用，我最好的建议是尝试通过导入您的 pom 文件（文件 > 导入项目并选择 pom）来创建新的 IDEA 项目。

哦，以防万一，请确保您使用的是最新版本的 IDEA，12.1.6（或您的许可证有效的最新版本）。有时它是简单的事情;）

您必须将 javax.servlet.jstl 库添加到项目的工件中，以便它将 jstl 库添加到 .war 文件中。希望这会有所帮助。
