I have added all JARs including jstl.jar& standard.jarbecause I assume this will required for the java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Configerror. However, it still displays HTTP 500 for the http://localhost:8080/passion/index.phpand HTTP 404 for http://localhost:8080/passion/.
我已经添加了包括jstl.jar和standard.jar在内的所有 JAR ，因为我认为这对于java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config错误是必需的。然而，它仍显示HTTP 500的HTTP：//本地主机：8080 /激情/ index.php的和HTTP 404为HTTP：//本地主机：8080 /激情/。

JARs should be in WEB-INF/lib, not subdirectories.
JAR 应该在 WEB-INF/lib 中，而不是子目录中。
If you're deploying on Tomcat, you might try putting those JSTL JARs in the Tomcat /lib so the server class loader can find them.
如果您在 Tomcat 上部署，您可以尝试将这些 JSTL JAR 放在 Tomcat /lib 中，以便服务器类加载器可以找到它们。

, Why do you redirect this page using?
，你为什么重定向这个页面使用？
<% response.sendRedirect("index.php"); %>
you can map index php as a welcome file. I did it the following way:
您可以将 index php 映射为欢迎文件。我是通过以下方式做到的：
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/index.php</url-pattern>
</servlet-mapping>
and then:
进而：
<welcome-file-list>
<welcome-file>index.php</welcome-file>
</welcome-file-list>
it will show your index.dlp as index file. Danny.
它会将您的 index.dlp 显示为索引文件。丹尼。

I think that you must be use tomcat and your pom.xml is like:
我认为你必须使用 tomcat 并且你的 pom.xml 是这样的：
<dependency>
<groupId>javax.servlet.jsp.jstl</groupId>
<artifactId>jstl-api</artifactId>
<version>1.2</version>
<scope>provided</scope>
</dependency>
delete the scope node, or change "provided" to "compile" then maven copy jstl-api-1.2.jar to the WEB-INF/lib.
删除范围节点，或将“provided”改为“compile”，然后maven将jstl-api-1.2.jar复制到WEB-INF/lib。
then OK.
然后确定。
