Java Question

JSP printing as plain text only

I am trying to print parameters using jstl but it renders as plain text even with EL expression. I tried to change version of servlet and dependencies but still facing same issue. I am using tomcat8.0.

web. xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name>Archetype Created Web Application</display-name>

<servlet>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

<context-param>

<listener>

Answer

The spring servlet needs to be the default servlet. ie mapped to / and not /*. Spring jsp page not evaluated

Just remove wildcard (*) from url pattern

<servlet>
<servlet-name>SpringMVC</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
   <servlet-name>SpringMVC</servlet-name>
   <url-pattern>/</url-pattern>
</servlet-mapping>
