Can't Post a message using Facebook's API, using MVC and Java

I was trying to use the facebook API to post a message to share a page I am making as a project to learn to use APIs.
And I'm running into the following problem.
I tried to post and I was redirected to facebook where I accepted a bunch of permisions and then I was redirected to the url "MyUrl/oauth2callback/Facebook?code=A very large code" and got a 404 Not Found error.
I'm not sure what the problem is and I have been trying to find it for the past 3 days, here is the resource I am using:
import org.restlet.resource.ClientResource;
public class FacebookPostResource {
private String uri = "https://graph.facebook.com/me/feed";
private String access_token = null;
public FacebookPostResource(String access_token) {
this.access_token = access_token;
}
public boolean publishPost(String message){
String normalizedMessage=message.replace(' ', '+');
ClientResource cr=new ClientResource(uri+"?access_token="+access_token);
cr.post("message="+normalizedMessage);
return true;
}
}
Here is the Controller:
public class FacebookPostController extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = -6818025976353856770L;
private static final Logger log =
Logger.getLogger(FacebookPostController.class.getName());
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws
IOException,ServletException {
String accessToken=(String)req.getSession().getAttribute("Facebook-
token");
if(accessToken!=null && !"".equals(accessToken)){
FacebookPostResource fbResource=new
FacebookPostResource(accessToken);
fbResource.publishPost(req.getParameter("message"));
req.getRequestDispatcher("/").forward(req,resp);
}else{
log.info("Trying to acces to Facebook without an acces token,
redirecting to OAuth servlet");
req.getRequestDispatcher("/AuthController/Facebook").forward(req,resp);
}
}
public void doPost(HttpServletRequest req, HttpServletResponse resp) throws
IOException,ServletException {
doGet(req,resp);
}
}
Here is My scope configuration:
{
"Facebook":{
"tokenUrl":"https://graph.facebook.com/v2.8/oauth/access_token",
"clientId":"MyID",
"clientSecret":"MySecret" ,
"authorizationFormUrl":"https://www.facebook.com/v2.8/dialog/oauth",
"scopes":["user_posts", "user_friends"]
}
}
Here is the JSP where I write the post:
<c:if test='${empty sessionScope["Facebook-token"]}'>
<c:redirect url = "/AuthController/Facebook"/>
</c:if>
<h1>Publicar Post en Facebook</h1>
<div class="container">
<p class="message"></p>
<form action="/facebookPostCreation" method="post">
Mensaje: <textarea name="message"></textarea>
<br>
<div class="bottom_links">
<button type="submit" class="button">Publicar en
Facebook</button>
<button type="button"
onClick="javascript:window.location.href='index.html'"
class="button">Cancel</button>
</div>
</form>
</div>
And finally here is my web.xml
...
<servlet>
<servlet-name>FacebookPostCreation</servlet-name>
<servlet-class>aiss.controller.FacebookPostController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>FacebookPostCreation</servlet-name>

<url-pattern>/OAuth2Callback/Facebook</url-pattern>
</servlet-mapping>

Try using my code
https://github.com/OswaldoRosalesA/FacebookAPIJava.git
Use Debuger.java to Test.
I use the Graph API

Url changed in spring

I have a from and when the form is filled and submitted I wanted the request to be http://localhost:8080/restroo/admin/adminLog but it gives http://localhost:808/adminLogand getting 404 error. I don't know why I am having this problem and actually I was having problem in using two controllers in spring.
web.xml
<servlet>
<servlet-name>spring</servlet-name>

</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
I have spring-servlet.xml
admin.jsp
<form method="post" action="/adminLog" modelAttribute="adminUser">

String userN = adminUser.get(i).getUserName();
String pass = adminUser.get(i).getPassword();
if(userN.equals(ad.getUserName()) && (pass.equals(ad.getPassword()))){
return new ModelAndView("adminLogin");
}
}
return new ModelAndView("admin");
}
}

You are using Internal Resource View Resolver It is not able fetch view Not In Web-INF Floader.
Find This http://www.baeldung.com/spring-mvc-view-resolver-tutorial.

You have to change servlet mapping by adding a prefix for the API of the whole app:
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/restroo</url-pattern>
</servlet-mapping>

Things I have tried inorder to resolve this but DID NOT WORK :
Set 'readonly' as false in tomcat's web.xml
Disabled csrf by adding
security:csrf disabled="true"
in root-context inside security:http tag.
Added CorsFilter
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
<init-param>
<param-name>cors.allowed.origins</param-name>

</init-param>
<init-param>
<param-name>cors.allowed.methods</param-name>
<param-value>GET, POST, PUT, DELETE, OPTIONS, HEAD</param-value>
I am still not able to get rid of the 403 error when it sends the put request.

I don't know if that is the problem, but just from reading your code:
in your js:
$scope.addToCart = function (productId) {
$http.put('/emusicstore/rest/cart/add/'+productId).success(function (data) {
$scope.refreshCart($http.get('/emusicstore/rest/cart/cartId'));
alert("Product successfully added to the cart!")
});};
and in your java:
#RequestMapping(value="/add/{productId}", method = RequestMethod.PUT)
#ResponseStatus(value = HttpStatus.NO_CONTENT)
public void addItem(#PathVariable (value = "productId") String productId, HttpServletRequest request) {
System.out.println("Inside addItem()");
String sessionId = request.getSession(true).getId();
Cart cart = cartDao.read(sessionId);
if(cart == null) {
cart = cartDao.create(new Cart(sessionId));
}
Product product = productDao.getProductById(Long.valueOf(productId));
if (product == null) {
throw new IllegalArgumentException(new Exception());
}
cart.addCartItem(new CartItem(product));
cartDao.update(sessionId, cart);
}
you're java returns no data in the response, but in the js your function expects the data.
note that 403 is usually bad mapping or security issues.

Why "response.sendRedirect" doesn't work?

This is my login part which I need to compare user input with data in the database.
So If a lecturer tries to enter the system, he or she will get into lecturer interface(lecturer.html) and same goes to the student.
But right now, when I try to enter the system using either lecturer or student ID, the system will direct me to the log in interface.
I hope someone can help me to solve this :)
This is the query for Java DB (LogIn.java)
public class LogIn extends HttpServlet {

I hope someone can help me to solve this problem.thanks :)

In your code you don't need to specify full URL in action you can just Specify abc.jsp or ServletName which is there in web.xml.
<form class="navbar-form navbar-right" role="form" method="get" action="LogIn">
Secondly you need to specify onClick in Submit button of your form.
<button type="submit" class="btn btn-success" onclick="action">Masuk</button>
EDIT
I'm getting this, every time I try to log in.
localhost:8080/Spedt/LogIn?matricin=A138&passwordin=92
So it's working and you need to do some stuff in your LogIn Servlet as your doGet method is Empty and better to Use POST for LogIn!!!

ohhh..
In this case control is not reaching to servlet so how would you expect to run redirect!!
In action part of your html you have written action="http://localhost:8080/Spedt/LogIn"
you should use action for your servlet which you have define in web.xml file
see your xml file is
<servlet>
<servlet-name>LogIn</servlet-name>
<servlet-class>mypkg.LogIn</servlet-class>
</servlet>
if your write action=LogIn then you will go to mypkg.LogIn servlet

Jquery ajax call to invoke spring controller?

I have below config in web.xml
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/mvc-dispatcher-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
I have controller as below.
#Controller
public class SomeController {
#RequestMapping(value = "/getData", method = RequestMethod.GET)
public ModelAndView showExtendedUi(#RequestParam("geo") String geo, #RequestParam("tab") String tab, #RequestParam("gid") String gid, HttpServletResponse response) {
//logic
}
}
Now how can i specify URL in jquery ajax call?
$.ajax({
type: "GET",
url: "getData.do",
dataType: "json",
success: function(responseJson) {
alert("json"+responseJson);
},
error: function(xhr, status, error) {
alert('Failed to get details: ' + error);
}
});

From looking at the code above, you should just be able to go to the following url (assuming 8080 port as default Tomcat port).
http://localhost:8080/getData.do?geo=1&tab=1&gid=1
This should show you in a browser the JSON you require. If the JSON appears on the page here, just do $.getJSON() from jQuery as it has built in methods for pulling back JSON. You can see the documentation on this method here.
