I am trying to send a sms using twillio, here the code:
import com.twilio.sdk.TwilioRestClient;
import com.twilio.sdk.TwilioRestException;
import org.apache.http.NameValuePair;
import org.apache.http.auth.Credentials;
import org.apache.http.message.BasicNameValuePair;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.logging.Logger;
public class SendSms extends HttpServlet {
private Logger logger = Logger.getLogger(SendSms.class.getName());
private TwilioRestClient client;
private Credentials credentials;
#Override
public void service(HttpServletRequest req, HttpServletResponse resp) throws IOException,
ServletException {
final String twilioAccountSid = System.getenv("TWILIO_ACCOUNT_SID");
final String twilioAuthToken = System.getenv("TWILIO_AUTH_TOKEN");
final String twilioNumber = System.getenv("TWILIO_NUMBER");
final String toNumber = (String) twilioNumber;
String message = "prova";
client = new TwilioRestClient(twilioAccountSid, twilioAuthToken);
sendMessage(toNumber, message);
}
public void sendMessage(String to, String message) {
List<NameValuePair> params = getParams(to, message);
try {
this.client.getAccount().getMessageFactory().create(params);
} catch (TwilioRestException exception) {
exception.printStackTrace();
}
}
private List<NameValuePair> getParams(String to, String message) {
List<NameValuePair> params = new ArrayList<>();
params.add(new BasicNameValuePair("Body", message));
params.add(new BasicNameValuePair("To", to));
params.add(new BasicNameValuePair("From", to));
return params;
}
}
Is just a test so I don't matter about performarce, code cleaning and so on. Calling the servlet I am getting the following error:
WARNING: Error for /SendSms
java.lang.NoClassDefFoundError: com/twilio/sdk/TwilioRestException
I am using maven, importing the related twillio apis, here the pom dependency:
<dependencies>
<dependency>
<groupId>com.twilio.sdk</groupId>
<artifactId>twilio-java-sdk</artifactId>
<version>(6.0,6.9)</version>
</dependency>
Does someone has some suggestions?
Thank you in advance.
Perhaps the missing <scope> for compile is the problem:
<dependency>
<groupId>com.twilio.sdk</groupId>
<artifactId>twilio-java-sdk</artifactId>
<version>(6.0,6.9)</version>
<scope>compile</scope>
</dependency>
And for the full detailed instructions regarding the dev environment:
https://www.twilio.com/docs/quickstart/java/devenvironment#pomxml
I have a tired application layered like this
WebServices
Services
DAO
Common
I call twilio in the services module, so I put the maven dependency in the pom file in that maven module. For some reason I kept getting the same error as you. Adding the dependency to the WebServices module fixed the issue

}
Using jdk1.8.0_77 on Windows 7
However, if I comment out the swagger dependency and the swagger specifics in the code, then the actual REST service works as expected. How can I make swagger work without using a servlet container? The REST service can work without it
dependencies {
compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:+'
compile 'org.glassfish.jersey.containers:jersey-container-jdk-http:+'
compile 'org.glassfish.jersey.media:jersey-media-moxy:+'
compile 'org.glassfish.jersey.media:jersey-media-json-jackson:+'
// compile 'io.swagger:swagger-jersey2-jaxrs:1.5.9'
}
code:
package example;
import static org.glassfish.jersey.jdkhttp.JdkHttpServerFactory.createHttpServer;
import java.net.URI;
import javax.ws.rs.core.UriBuilder;
import org.glassfish.jersey.jackson.JacksonFeature;

public class MyApp extends ResourceConfig {
public static void main(String[] args) throws Throwable {
URI baseUri = UriBuilder.fromUri("http://localhost/").port(9999).build();
HttpServer server = createHttpServer(baseUri, new MyApp());
System.out.println("SERVICE started at: " + baseUri);
Runtime.getRuntime().addShutdownHook(new Thread(() -> {
server.stop(0);
}));
}
public MyApp() {
packages("example");
// register(SwaggerSerializers.class); // <-- swagger specific
// register(ApiListingResource.class); // <-- swagger specific
register(JacksonFeature.class);
}
}
So it looks like the issue is derived from you running in a non-servlet environment. While Jersey supports it, swagger-core... not so much. This poses some issues with specific deployment, although they are less common.
The easiest solution would, obviously, be to use a servlet-container engine. Something lightweight like Jetty would work.
I know that is a litlle bit late, but I have the same issue and came up with a solution to run swagger on a non-servlet environment.
Hope to be helpful for the next devs.

Any questions, please ask.
I was facing the same issue, I solved it by following the same swagger documentation, The only difference is that I provided my own ApiListingResource implementation
package com.example;
import com.fasterxml.jackson.core.JsonProcessingException;
import io.swagger.annotations.ApiOperation;
import io.swagger.jaxrs.config.BeanConfig;
import io.swagger.models.Swagger;
import io.swagger.util.Yaml;
import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
#Path("/docs")
#ApplicationScoped
public class ApiListingResource {
private final Swagger swagger;
public ApiListingResource() {
BeanConfig beanConfig = new BeanConfig();
beanConfig.setTitle("MY REST API");
beanConfig.setVersion("v1");
beanConfig.setBasePath("/api");
beanConfig.setResourcePackage("com.example.resource");
beanConfig.setScan(true);
this.swagger = beanConfig.getSwagger();
}
#GET
#Produces({"application/json"})
#Path("/swagger.json")
public Response getListingJson() {
return Response.ok(this.swagger).build();
}
#GET
#Produces({"application/yaml"})
#Path("/swagger.yaml")
public Response getListingYaml() throws JsonProcessingException {
String yaml = Yaml.mapper().writeValueAsString(this.swagger);
return Response.ok(yaml).build();
}
}
Then I registered the resource along with the SwaggerSerializers provider.
I need verify header before receive the request. I found that tomcat valve can help in it. I follow these steps but valve is not called:
make a maven project and do this code in it.
package cz.ValveTest;
import java.io.IOException;
import java.util.Enumeration;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import org.apache.catalina.connector.Request;
import org.apache.catalina.connector.Response;
import org.apache.catalina.valves.ValveBase;
public class ProcessingValve extends ValveBase {
private static final Logger logger = Logger.getLogger(ProcessingValve.class.getName());
#Override
public void invoke(Request request, Response response) throws IOException,
ServletException {
HttpServletRequest httpServletRequest = request.getRequest();
Enumeration<String> headerNames = httpServletRequest.getHeaderNames();
logger.info("++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++");
while (headerNames.hasMoreElements()) {
String header = headerNames.nextElement();
logger.log(Level.INFO, "Header --> {0} Value --> {1}", new Object[]{header, httpServletRequest.getHeader(header)});
}
getNext().invoke(request, response);
}
}
make jar and put jar inside tomcat/lib folder
add this line in server.xml
<valve className="cz.ValveTest.ProcessingValve"/>
restart tomcat.
Now I hit my web service with header:
Expect : 100-continue
but using this configuration and code valve is not called on http hit.If any one knew why tomcat valve is not called please help.
The tags in server.xml are case sensitive.
So try this :
<Valve className="cz.ValveTest.ProcessingValve"/>
How do I connect to Solr 1.4 search server configured with Basic Auth using the SolrJ 3.6 connector?

I am running the YouTubeSample given on the google developers website. I have no errors in the code and my imports appear to be fine. But when I run the project I get the aforementioned error.
I have done some searches but to be honest I have been unable to work out what the problem is. I have already tried importing an external jar guava but it didn't help.
Any help is appreciated. Here is the full class
package com.pengilleys.googlesamples;

#Key final String alt = "jsonc";
#Key String author;

YouTubeUrl(String url) {
super(url);
}
}
public static void main(String[] args) throws IOException {
// set up the HTTP request factory
HttpTransport transport = new NetHttpTransport();
final JsonFactory jsonFactory = new JacksonFactory();
HttpRequestFactory factory = transport.createRequestFactory(new HttpRequestInitializer() {
#Override
public void initialize(HttpRequest request) {
// set the parser
JsonCParser parser = new JsonCParser();
parser.jsonFactory = jsonFactory;
request.addParser(parser);
// set up the Google headers
GoogleHeaders headers = new GoogleHeaders();
headers.setApplicationName("Google-YouTubeSample/1.0");
headers.gdataVersion = "2";
request.headers = headers;
}
});
// build the YouTube URL
YouTubeUrl url = new YouTubeUrl("https://gdata.youtube.com/feeds/api/videos");
url.author = "searchstories";
url.maxResults = 2;
// build the HTTP GET request
HttpRequest request = factory.buildGetRequest(url);
// execute the request and the parse video feed
VideoFeed feed = request.execute().parseAs(VideoFeed.class);
for (Video video : feed.items) {
System.out.println();
System.out.println("Video title: " + video.title);
System.out.println("Description: " + video.description);
System.out.println("Play URL: " + video.player.defaultUrl);
}
}
}
The setup documentation gives a list of dependencies:
Depending on the application you are building, you may also need these dependencies:
Apache HTTP Client version 4.0.3
Google Guava version r09
Jackson version 1.6.7
Google GSON version 1.6
In this case, it looks like it's Guava which is missing. I don't know what you mean about "exporting" Guava, but if you include the Guava r09 jar file in the classpath when you're running the code, it should be fine.
what's the extra ); for above the // build the YouTube URL and did you mean to close main on that line?
