Why is JSP view not being resolved? - spring

Question

I am trying to deploy a Spring web app on Tomcat 7.0.42 with Servlet 3.0. The default home of the app is opening fine, but when I try to navigate from the home, I am getting a 404. Please find details below.
My servlet-contex.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<beans:property name="suffix" value=".jsp" />
</beans:bean>
<context:component-scan base-package="com.portfolio.chota" />
</beans:beans>
My web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
And here is my controller
#RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model,HttpSession session,HttpServletRequest request) {
// Do some stuff
return "home";
}
#RequestMapping(value = "/profile", method = RequestMethod.GET)
public String profile(Locale locale, Model model,HttpServletRequest request) {
String pAge = (String)request.getSession().getAttribute("SAVINGSAMOUNTTYPE");
if(pAge==null || pAge.equals(""))
return "redirect:/sessionOut";
else
return "profile";
}
When I access the app the home is loading fine, but when I try to move to /profile from the home, I am getting the following 404
Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.111 Safari/537.36 404 /abc/profile
PROBLEM SOLVED
I found out the problem was with the cp_jkmount.conf file in these locations -
/usr/local/apache/conf/userdata/std/2/xyz/domain.com/
/usr/local/apache/conf/userdata/ssl/2/xyz/domain.com/
Here xyz is the user & domain.com is the domain for which you are trying to set this.
This was set to mount *.jsp & *.do files such that requests with these extensions were only being sent to the Tomcat daemon. Since ours is a Spring app without any extension in its requests that's why those requests were not being served to Tomcat.
These were the original entries in cp_jkmount.conf
JkMount /*.jsp ajp13
JkMount /*.do ajp13
I have now updated this to
JkMount /* ajp13
Since this domain hosts only pure java based apps, thats why all my requests are now served to Tomcat & thus my problem has been resolved.
Hope this helps someone of you too.
