getting an error in sending a value to RequestParam from JSP file

I have the following code:

<c:forEach var="listValue" items="${upcomingMovieslists}">
        div style="border:thin inset #6E6E6E; text-align: justify;> <p margin-left: 1em;">&nbsp;&nbsp;<c:set var="movieName" scope="application" value="${listValue.key}"/><a  href="/myapp/movie/SubmitMovie/" >${listValue.key}</a></p></div>
</c:forEach>

and movieName is going to be in @RequestParam String movieName in the page that it is going next.

So, When I run this code I am getting an error telling:

error:
message Required String parameter 'movieName' is not present

description The request sent by the client was syntactically incorrect.

Controller method:

My controller class to where the call is going:

@RequestMapping(value="/SubmitMovie", method = RequestMethod.GET)
public ModelAndView getSearchedMovie(@RequestParam String movieName, ModelMap model)

The URL currently is: /myapp/movie/SubmitMovie/

It should be /myapp/movie/SubmitMovie/?movieName=deadpool in order to work

I should have /?movieName= to show the results in the next page but where as with the above jsp code I will not get the movieName in String format instead it comes in the form ${movieName} which cannot be accepted to a String present in the RequestParam and hence it throws an error.

I want to know how I can fix it to get the moviename in Stringformat in the URL so that I can populate the results

Thanks

There's not a whole lot of code there, so I don't know exactly what you're going for, but you can always add a required=false condition to a request parameter, like so:

@RequestParam(value = "movieName", required = false) String movieName

That should at least clear that error. If the logic in your model does require movieName, though, then you're going to need to refactor around that -- i.e., your link would need to look like href="/myapp/movie/SubmitMovie?movieName='${listValue.key}'" .

(Note: I'm inferring from your code that ${listValue.key} is the name of the movie. Whatever variable you want the controller to receive as the @RequestParam String movieName, place it after ?movieName= in the href string, after escaping it with single quotes (see how I did so above.)

If you're still stuck, maybe try showing the controller for the page with that parameter?
