I created libfolder under WEB-INFand put jstl-1.2.jaron it, as you can see in the picture:
我在lib下面创建了文件夹WEB-INF并将其放在jstl-1.2.jar上面，如图所示：
But i have the same problem yet.
但我还有同样的问题。

You need to add the jstl tag library to the WEB-INF/lib folder. if you don't have one you make the lib folder. Download JAR from https://mvnrepository.com/artifact/javax.servlet/jstl/1.2
您需要将jstl 标记库添加到WEB-INF/lib 文件夹中。如果您没有，则创建 lib 文件夹。从https://mvnrepository.com/artifact/javax.servlet/jstl/1.2下载 JAR
Adding Maven Dependency Does Not Work.
添加 Maven 依赖项不起作用。

回答by mfruizs2
In my case, I had got the library on pom, but with scope as provided.
就我而言，我在 pom 上获得了库，但范围为provided.
In that case, we need to add the library on your server, maybe /libor in your proyect WEB-INF/lib
在这种情况下，我们需要在您的服务器上/lib或在您的项目中添加该库WEB-INF/lib
On the other hand, we can remove that scope.
另一方面，我们可以删除该范围。
回答by Waldo Alvarez
Very simple to fix. In Netbeans left click your project, click properties, choose libraries and there click "add library". There you choose "JSTL 1.2.1" and click the new "add library" in the dialog.
修复起来非常简单。在 Netbeans 中左键单击您的项目，单击属性，选择库，然后单击“添加库”。在那里您选择“JSTL 1.2.1”并在对话框中单击新的“添加库”。
