Here is my Project Structure Project Structure 这是我的项目结构项目结构

Web.xml 在web.xml

When i remove the First line from the index.jsp ie the taglib line, everything works fine. 当我从index.jsp即taglib行中删除第一行时，一切正常。 I think I have imported all the required depnedencies in the pom.xml. 我想我已经在pom.xml中导入了所有必需的代理。

Please let me know what i am doing wrong? 请让我知道我做错了吗？

I agree with @Balus C, You are using IntelliJ Idea. 我同意@Balus C，您正在使用IntelliJ Idea。 I am using Intellij Idea 15 我正在使用Intellij Idea 15

The problem is with POM.XML 问题出在POM.XML

I changed your POM.XML as 我将您的POM.XML更改为

Added - Packaging Type to WAR 已添加-WAR的包装类型

 <groupId>zambroo.crud6</groupId> <artifactId>crud6</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging>

Added BUILD Details after Dependencies node ends Dependencies节点结束后添加了BUILD详细信息

  <build> <sourceDirectory>src/main/java</sourceDirectory> <resources> <resource> <directory>src/main/resources</directory> </resource> </resources> <testSourceDirectory>src/test/java/unit</testSourceDirectory> <testResources> <testResource> <directory>src/test/java/resources</directory> </testResource> </testResources> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.3</version> <configuration> <warSourceDirectory>web</warSourceDirectory> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build>

Now everything works Fine for me!!!!!! 现在一切都对我很好!!!!!!

Hope this HELPS you JwB! 希望这对您有所帮助！

Answer 2

I believe the issue is in your pom. 我相信问题出在您的pom中。 Simply put, the container doesn't think that the JSTL library is there when it is deployed, or there is a conflict. 简而言之，容器在部署时不认为存在JSTL库，否则就不会发生冲突。

You're specifically including the JSTL directly, version 1.2.1 and then also including the glassfish implementation of it (so, which do you want?). 具体来说，您直接包含了JSTL 1.2.1版，然后还包含了它的glassfish实现（因此，您想要哪个？）。

You've excluded almost everything that glassfish provides anyway. 无论如何，您几乎排除了玻璃鱼提供的所有内容。 There is likely something not working with your exclusions. 您的排除项可能不起作用。 I would remove the glassfish dependency all together and see if it plays nicer. 我将全部删除glassfish依赖项，看看它是否更好。

You could remove them both and simply try this one: 您可以将它们都删除，然后只需尝试以下一项：

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

Answer 3

Try this: 尝试这个：
-right click on your maven project; -右键单击您的Maven项目；
-go to "maven" and then click on "Update project". -转到“行家”，然后单击“更新项目”。

It works for me. 这个对我有用。
