No resource classes found on a cxf Servlet - cxf

I have created a very simple cxf non-spring based Servlet which loads a javax.ws.rs.Application type.
Here is the web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<servlet>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>
org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet
</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>
com.mycomp.cxf.TestApplication
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
And here is the application:
public class TestApplication extends Application
{
private final Set<Class<?>> classes = new HashSet<Class<?>>();
private final Set<Object> singletons = new HashSet<Object>();
public TestApplication() throws ServletException
{
}
#Override
public Set<Class<?>> getClasses()
{
return classes;
}
#Override
public Set<Object> getSingletons()
{
return singletons;
}
}
The Servlet is failing to load due to: "No resource classes found" and i'm not sure why as it should be ok to have an empty set of classes in Application.
Here is the full stacktrace:

You need to notify your environment of your serviceclasses. You first need to add the service class, otherwise you will just return null in getSingletons()
So just change your now empty constructor to add the service class:
class TestApplication extends Application {
public TestApplication() throws ServletException
{
singletons.add( new com.example.MyService() )
}
....
}

Well, I guess you can't have an empty set of classes as if I add one then it loads successfully, for example:
public TestApplication() throws ServletException
{
singletons.add(someClass);
}

Failed to generate endpoints api with maven using Multiclass API - Java Inheritance

I based my endpoint classes from this example
#Api(name = "tictactoe", version = "v1")
class TicTacToeBase { … }
// TicTacToeA and TicTacToeB both behave as if they have the same #Api annotation as
// TicTacToeBase
class TicTacToeA extends TicTacToeBase { … }
class TicTacToeB extends TicTacToeBase { … }
Endpoints works perfectly with android studio's gradle.
but when I move the source files to my maven-structured project it doesn't recognized TicTacToeA & TicTacToeB as endpoints classes. I've tried to use just simple annotated Endpoint class and it works.
web.xml contents from gradle-structured project is also copied to maven-structured project.
I noticed from target folder of maven-structured project that web.xml was generated but this time only with
<param-value>com.sample.TicTacToeBase</param-value>
shouldn't it be
<param-value>com.sample.TicTacToeA,com.sample.TicTacToeB</param-value>?
You are right! Each API needs to be declared in the web.xml file. Normally you can do this in the file src/main/webapp/WEB-INF/web.xml. (the web.xml file in the target folder is just a copy)
For example, you have a class TicTacToeAPI with annotations which define your API and two subclasses which extend this one.
TicTacToeAPI
#Api(name = "tictactoe",
canonicalName = "TicTacToe API",
version = "v1",
title = "TicTacToe Client API",
description = "TicTacToe Client API.",
namespace = #ApiNamespace(
ownerName = "tictactoe.com",
ownerDomain = "tictactoe.com")
)
public class TicTacToeAPI {
// ...
}
TicTacToeA & TicTacToeB
public class TicTacToeA extends TicTacToeAPI {
// Exposes some methods using annotations.
}
public class TicTacToeB extends TicTacToeAPI {
// Exposes some methods using annotations.
}
In your web.xml file, you cannot declare only the top level class. All subclasses have to be defined.

Spring CSRF + AngularJs

I Already tried many of the aswers about this topic, no one works for me.
I Have a basic CRUD with Spring MVC 4.1.7, Spring Security 3.2.3 working on MySQL + Tomcat7.
The problem is, when i try to POST form with AngularJS, I keep being blocked by error 403 ( access denied ).
I figured out that I need to send my CSRF_TOKEN with the POST request, but I can't figure out HOW!
I Tried so many diferent ways and no one works.
My Files
Controller.js
$scope.novo = function novo() {
if($scope.id){
alert("Update - " + $scope.id);
}

saldo : 33.45,

$http.post(urlBase + 'caixas/adicionar', Obj).success(function(data) {
$scope.caixas = data;

UPDATE
I tried to add to rename at client side the xsrf, but I keep getting access denied.
var app = angular.module('myApp', []).config(function($httpProvider) {
$httpProvider.defaults.xsrfCookieName = '_csrf';
$httpProvider.defaults.xsrfHeaderName = 'X-CSRF-Token';
});
** UPDATE 2 **
I tried to implement a filter like this.
package sys.barattie.util;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.security.web.csrf.CsrfToken;
import org.springframework.web.filter.OncePerRequestFilter;
public class CsrfFilter extends OncePerRequestFilter {
#Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class.getName());
if (csrf != null) {
Cookie cookie = new Cookie("XSRF-TOKEN", csrf.getToken());
cookie.setPath("/");
response.addCookie(cookie);
}
filterChain.doFilter(request, response);
}
}
And changed my spring security to it.
<csrf token-repository-ref="csrfTokenRepository" />
<beans:bean id="csrfTokenRepository" class="org.springframework.security.web.csrf.HttpSessionCsrfTokenRepository">
<beans:property name="headerName" value="X-XSRF-TOKEN" />
</beans:bean>
Web.xml
<filter>
<filter-name>csrfFilter</filter-name>
<filter-class>sys.barattie.util.CsrfFilter</filter-class>
</filter>
But it is like that the server doesn't run the filter, I've added a System.out.println to it, but can't see the messages in the debug
I did some tests and end up with this.
In my login controller, if my user authentication is successful, I create a token with the name of the AngularJS Token, just like this.
CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class.getName());
if (csrf != null) {
Cookie cookie = new Cookie("XSRF-TOKEN", csrf.getToken());
cookie.setPath("/");
response.addCookie(cookie);
}
After that, I can manage my $http.post successfully.
I don't know if this is the best way, but is the way that worked for me!
Thanks for the help #Joao Evangelista
The main problem is the integration, Angular always look for a cookie name XSRF-TOKEN and Spring sends a CSRF_TOKEN, you need to provide a filter to change this. Something like this:
private static Filter csrfHeaderFilter() {
return new OncePerRequestFilter() {
#Override
protected void doFilterInternal(HttpServletRequest request,
HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class.getName())
if (csrf != null) {
Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN")
String token = csrf.getToken()
if (cookie == null || token != null && !token.equals(cookie.getValue())) {
cookie = new Cookie("XSRF-TOKEN", token)
cookie.setPath("/")
response.addCookie(cookie)
}
}
filterChain.doFilter(request, response)
}
}
}
static CsrfTokenRepository csrfTokenRepository() {
HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository()
repository.setHeaderName("X-XSRF-TOKEN")
return repository
}
NOTICE The only example I have is this, is written in Groovy, but is just missing some ;
Then you need to add the filter and the repository to <csrf/> properties, you can explicity set a class implementing a Filter as <bean>, using #Component or declaring this methods as #Bean on a configuration class
Otherwise you can change the $http configuration on Angular, according to docs setting this settings to match Spring token cookie name and header name
xsrfHeaderName – {string} – Name of HTTP header to populate with the XSRF token.
xsrfCookieName – {string} – Name of cookie containing the XSRF token.
More info about this you can check the docs on Usage section
i was facing this problem also, and this is the solution that is working for me (from the Spring documentation), notice that im not using $http. Instead im using $resource.
'
You can ask Spring to save a cookie with Angular's defaults:
<csrf token-repository-ref="tokenRepository"/>
...
</http>
<b:bean id="tokenRepository"
class="org.springframework.security.web.csrf.CookieCsrfTokenRepository"
p:cookieHttpOnly="false"/>
Please notice that if you use $http, there is a field in the config object called xsrfCookieName, where you can set explicitly the name of the cookie. But this option i havent tried it, so i dont know how useful it is.
Best Regards.
This should work:
Class that extends WebSecurityConfigurerAdapter:
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
..
And then in your AngularJS you can use any module for csrf, etc.: spring-security-csrf-token-interceptor

Uploading files with PrimeFaces 4.0 , and jsf 2.2 on google app engine

I'm using:
-primefaces 4.0
-jsf mojarra 2.2
-google app engine (servlet api 2.5)
and this solution (Getting primefaces p:fileUpload to work under google appengine) doesn't help me because my version of primefaces is higher. There is exception when I'm using my form below with p:commandButton:

and this is because google don't support servlet api 3.0. I realy can't find a solution for now. Running primefaces 3.5 is not a option because the project is with JSF 2.2 and 2.2 is not compatible with primefaces 3.5.
One usable comment from this topic: How to use PrimeFaces p:fileUpload? Listener method is never invoked or UploadedFile is null
Update: since PrimeFaces 4.x, when used in combination with JSF 2.2 and Servlet 3.0, the filter is not necessary anymore. The Servlet 3.0 / JSF 2.2 native API will be used instead of Apache Commons FileUpload. Other rules however still apply and from the possible causes you can scratch #1 and #2.
My form:
<h:form enctype="multipart/form-data">
<p:fileUpload id="filePhoto" fileUploadListener="#{atlasCasesMB.handleFileUpload}" mode="advanced" dragDropSupport="false"
update=":messages" sizeLimit="614400" fileLimit="3" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
</h:form>
In this form fileUploadListener is not invoked.
I've tried to use the solution from this topic: Getting primefaces p:fileUpload to work under google appengine modify the DiskFileItem), but obviously this cannot help because JSF 2.2 uses native API instead of Apache Commons FileUpload.
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>

</init-param>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
Any suggestions? (Downgrading primefaces and jsf is not an option because the project is in final stage)
The solution ,that I tried, is to force primefaces to use apache common file upload (commons-fileupload-1.3.jar) using this:
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value>
</context-param>
Then I used the filter:
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
<init-param>
<param-name>thresholdSize</param-name>
<param-value>2147483647</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
important here is to set thresholdSize so big that write method in some of the apache common classes(I forgot which) is not invoked. And finally add the filter FileUploadFilter from primefaces 4.0 source files: http://www.primefaces.org/downloads.html
All sources that I used to get to this point:

there is second way to do this:
using multipart request to jersey:

<form action="rest/case" method="post" enctype="multipart/form-data">
<p>#{bundle['upload.photo.select.images.to.upload']}</p>

<input id="photo1" type="file" name="photo1" />
<br />
<input id="photo2" type="file" name="photo2" />
<br />
<input id="photo3" type="file" name="photo3" />
<br />
<input id="caseId" type="text" name="caseId" style="display:none" value="#{atlasCasesMB.savedCaseId}" />
<br />
<input id="btn-post" class="active btn" type="submit" value="Send" />
</form>
#POST

GAE - cannot deploy gwt app which uses UserService

I tried to deploy my app using auth this instructions as :
<application>mytestapp</application>
<version>1</version>
<sessions-enabled>true</sessions-enabled>
<security-constraint>
<web-resource-collection>
<web-resource-name></web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>*</role-name>
</auth-constraint>
</security-constraint>
and I tried this code as well to make user login:
public class GuestbookServlet extends HttpServlet {
#Override
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user != null) {
resp.setContentType("text/plain");
resp.getWriter().println("Hello, " + user.getNickname());
} else {
resp.sendRedirect(userService.createLoginURL(req.getRequestURI()));
}
}
}
... but for some reason I get exception thrown as XML error validating :
An internal error occurred during: "Deploying testapp to Google". XML
error validating C:...\testapp\war\WEB-INF\appengine-web.xml against
C:...\eclipse-jee-indigo-win32\eclipse\plugins\com.google.appengine.eclipse.sdkbundle_1.5.2.r37v201107211953\appengine-java-sdk-1.5.2\docs\appengine-web.xsd
I am not pretty sure what that means so I dearly need your advise how to fix it? Any useful idea is much appreciated.
Thanks
P.S. GWT SDK 2.3
You are mixing the app config file: appengine-web.xml with deployment descriptor: web.xml.

Jersey Google app engine - Resource not found

I am deploying a sample app in Google App Engine that uses Jersey. However when I try to do a GET or POST to the REST resource I get a - 404 NOT FOUND error. Looks like I am missing something.
REST resource code:
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.codehaus.jettison.json.JSONObject;
#Path("/stream")
public class StreamingResource {
private static final Logger log = Logger
.getLogger(FacebookStreamingResource.class.getName());
#POST
#Path("/callback")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.TEXT_PLAIN)
public String putStreamData(JSONObject jsonEntity) {
return jsonEntity.toString();
}
#GET
#Path("/get")
#Produces(MediaType.TEXT_PLAIN)
public String getStreamData() {
return "Get successful";
}
}

Any suggestions would be greatly appreciated :)
When I changed the in web.xml from /stream/* to /* it works :)
