这个问题通常是由于缺少 JSTL 库或者没有正确导入库文件所致。你可以尝试以下步骤来解决这个问题:
1. 确认你已经下载并正确导入了 JSTL 库文件,可以从官网下载并解压。
2. 确认你在 JSP 页面的头部引入了 JSTL 标签库,例如:
```html
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
```
3. 确认你的项目配置正确,可以在项目的 WebContent/WEB-INF/lib 目录下看到 jstl.jar 和 standard.jar 两个文件,如果缺少,可以手动将它们添加到项目中。
4. 如果以上步骤都没有解决问题,可以尝试在项目的构建路径中添加 JSTL 库文件,或者删除并重新导入库文件。

This error occurs when the JSTL (JavaServer Pages Standard Tag Library) core library is not properly configured in your web application. To resolve this error, you need to follow these steps:
1. Download the JSTL library from the official website (https://github.com/eclipse-ee4j/jstl-api).
2. Extract the downloaded file and copy the jstl-1.2.jar file to the WEB-INF/lib directory of your web application.
3. Add the JSTL core library to your web application by adding the following lines of code to your JSP page:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
4. Save the changes and refresh your web application. The error should be resolved.
If you are still facing the same issue, make sure that your web application is properly configured to use JSTL. You can check the web.xml file in the WEB-INF directory to make sure that the JSTL library is properly configured.

这个错误信息表明在 JSP 页面中找不到 "http://java.sun.com/jsp/jstl/core" 标签库描述符。这通常是由于 JSTL 的 jar 包没有正确安装或引用导致的。建议检查项目中是否已经正确引入了 JSTL 的 jar 包,并确保在 JSP 页面中引用了正确的标签库。
