how a servlet present in a package can be mapped outside welcome file-list

Question

I am getting confused about mapping a servlet.Actually i have two files index.jsp in the webcontent and another file Ihome.jsp in "Sales/Ihome.jsp" of the webcontent.When i run the server and chose "Sales/Ihome.jsp" as the welcome-file and type "s" in a textbox then i am able to display the data as shown below.

But when i am chosing "index.jsp" as welcome-file and then clicking on sales and clicking on "Ihome.jsp" and i type a letter in the textbox it is not showing the data as it has shown above.So how to map the servlet so that i can get the data without putting "Sales/Ihome.jsp" in welcome-file list.I am posting the code below

web.xml

<welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
     <servlet>
    <servlet-name>SearchController</servlet-name>
    <servlet-class>com.controller.Controller</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>SearchController</servlet-name>
    <url-pattern>/SearchController</url-pattern>
  </servlet-mapping>

I am getting like this when i type in the textbox

yes when i type some thing in the textbox it should go to the respective servlet as i mentioned in the javascript of "Ihome.jsp" — FIFA oneterahertz, Apr 28 '16 at 10:22
use @RequestMapping annotation on top of your controller. for example @RequestMapping("/check") will dispatch to the controller when localhost.../check is requested by user. — Mohammadreza Khatami, Apr 28 '16 at 10:23
Its a struts application so what import statement i have to use for requestmapping — FIFA oneterahertz, Apr 28 '16 at 10:33
check this for struts request mapping http://stackoverflow.com/questions/12401350/struts-2-request-mapping — Mohammadreza Khatami, Apr 28 '16 at 10:34
I typed above the controller @RequestMapping("/SearchController") and then its showing "RequestMapping cannot be resolved to a type" — FIFA oneterahertz, Apr 28 '16 at 10:40
@RequestMapping is Spring MVC related. I do not see that the questioner is using Spring MVC...... — Alan Hay, Apr 28 '16 at 10:40
You are using Struts 2 but at the same time you are writing raw servlets??? Anyway regardless of that you should never allow navigation directly to .jsp. Every action must go through a Servlet/Controller or whatever otherwise the data model will not be populated. — Alan Hay, Apr 28 '16 at 10:44
@AlanHay The main problem i am facing is if i place the required file in welcomefile-list then its working but if i placed outside welcomefile-list then its not working — FIFA oneterahertz, Apr 28 '16 at 10:48
Look at the browser dev tools. Call to load JS libraries or call to Servlet may return 404. — Alan Hay, Apr 28 '16 at 10:52
@AlanHay I am getting confused now if there are any changes in the servlet say it — FIFA oneterahertz, Apr 28 '16 at 10:54
You're writing the `autocomplete` function inside `Sales/Ihome.jsp` file. As well I couldn't able to locate your `index.jsp` in directory structure and in code — Vinoth Krishnan, Apr 28 '16 at 11:14
@VinothKrishnan I posted the code and directory of index.jsp — FIFA oneterahertz, Apr 28 '16 at 11:18
`ajaxcomplete` don't have any relation with `welcomefile-list`. Please check your browser console when you're pressing the key inside organization name. If you find any errors under console tab (since ajax request) post it here. — Vinoth Krishnan, Apr 28 '16 at 11:25
@VinothKrishnan I posted an image when i type a letter inside the organisation name — FIFA oneterahertz, Apr 28 '16 at 11:34

@VinothKrishnan I got an answer but the logic i wrote is correct or not i dont know.Can you please tell me whether its right or wrong. — FIFA oneterahertz, Apr 29 '16 at 06:56
Actually in my web.xml i wrote url-pattern as /Sales/SearchController — FIFA oneterahertz, Apr 29 '16 at 06:57
Like that which ever jsp page requires autocomplete jquery function i am writing url-pattern for those pages.If i need it in another page.Eg:- /Home/SearchController /quotation/SearchController — FIFA oneterahertz, Apr 29 '16 at 06:59

 <servlet>
    <servlet-name>SearchController</servlet-name>
    <servlet-class>com.controller.Controller</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>SearchController</servlet-name>
    <url-pattern>/Sales/SearchController</url-pattern>
  </servlet-mapping>

Just placed the required folder in which the jsp page is there and it worked very well
