Spring - The requested resource is not available

Question

I am trying to build a basic Java app with Spring MVC, however, I am having troubles with links within the app.

Here is my web.xml

<servlet>
    <servlet-name>test</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/test-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>test</servlet-name>
    <url-pattern>/</url-pattern>
    <url-pattern>/welcome.jsp</url-pattern>
    <url-pattern>/welcome.html</url-pattern>
</servlet-mapping>

My test-servlet.xml

<mvc:annotation-driven />
<mvc:default-servlet-handler/>
<context:component-scan base-package="com.springtest.controller"/>

<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">

    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix">
        <value>./WEB-INF/jsp/</value>
    </property>
    <property name="suffix">
        <value>.jsp </value>
    </property>

</bean>

The first page that gets displayed when running the app is the following:

<html>
<head>
    <title>Spring MVC Tutorial</title>
</head>
<body>
<br>
<div style="text-align:center">
    <h3>
        <a href="welcome">Click to say hello </a>
    </h3>
</div>
</body>
</html>

And welcome.jsp is this:

<html>
<head>
    <title>Hello World MVC</title>

</head>
<body>${message}

</body>
</html>

Since this is my first time using Spring (and I know there are a lot of questions here asking/answering this - thus I haven't been able to find an answer that helps me), I followed an online tutorial .

My folder structer is similar to what they have in the tutorial, however, every time I click the link to go to the second page, I get a 404 Error saying that:

/SpringTutorial-1.0-SNAPSHOT/WEB-INF/jsp/welcome.jsp - is not available

Answer 1

Basically / in the <url-pattern> tag is enough.It will take of /welcome.jsp or /welcome.html .

 <servlet-mapping> <servlet-name>test</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>

No need to give relative path in value property of prefix .

 <property name="prefix"> <value>/WEB-INF/jsp/</value> </property>

And one more thing is you can also try with InternalResourceViewResolver in place of UrlBasedViewResolver .

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
      <property name="prefix" value="/WEB-INF/jsp" />  
      <property name="suffix" value=".jsp" />  
</bean>

Change your form action to welcome.html

<html>
<head>
    <title>Spring MVC Tutorial</title>
</head>
<body>
<br>
<div style="text-align:center">
    <h3>
        <a href="welcome.html">Click to say hello </a>
    </h3>
</div>
</body>
</html>

also change url pattern to / or *.html


<servlet>
    <servlet-name>test</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/test-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>test</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>

also view resolver to internal resource view resolver and avoid giving relative url in it.

Also make sure that you have given @controller annotation. And URL mapping as @requestmapping("/welcome")
