Integration error jersey-multipart and swagger - java

I have a JAX-RS webservice using Jersey-1. There is only a single method at the moment, which sends mails with attachment. The attachment has to be provided as a multipart form data.
#POST
#Path("/mail")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response sendInfomailWithAttachment(
#Context ServletContext context,
#Context SecurityContext security,
#QueryParam ("FROM") String senderAddress,
#QueryParam ("SUBJECT") String subject,
#QueryParam ("TO") String toRecipients,
#QueryParam ("CC") String ccRecipients,
#QueryParam ("BCC") String bccRecipients,
#QueryParam ("noCopy") boolean sendNoCopy,
#FormDataParam("attachment") InputStream fileInputStream,
#FormDataParam("attachment") FormDataContentDisposition contentDispositionHeader,
#FormDataParam("attachment") FormDataBodyPart fileBody,
#FormDataParam("content") FormDataBodyPart content
){}
The method works fine. But when I try to integrate swagger, I always get this error(s):
SEVERE: Missing dependency for method public javax.ws.rs.core.Response ... throws java.lang.Exception at parameter at index 8
(this error is thrown for param 9, 10 and 11 as well)
in combination with
SEVERE: Method, public javax.ws.rs.core.Response ... throws java.lang.Exception, annotated with POST of resource, class com.mywebservice.MyClass, is not recognized as valid resource method.
If I throw out the FormDataParam stuff, the service starts normally, also with the swagger integration.
I use
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.3</version>
</dependency>
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-servlet</artifactId>
<version>1.17</version>
</dependency>
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
<artifactId>jersey-multipart</artifactId>
<version>1.17</version>
</dependency>
and
<dependency>
<groupId>com.wordnik</groupId>
<artifactId>swagger-jersey-jaxrs_2.10</artifactId>
<version>1.3.4</version>
</dependency>
Is there any known interference? Anything else I could do to come around this?

As I found out, it was a maven resolution problem.
The swagger lib 1.3.4 uses jersey-core-1.3 and jersey-server-1.3, which has been chosen by maven. Instead, I needed it in 1.17 like the jersey-servlet and jersey-multipart version. So I had to add those two dependencies to the pom to make the maven dependency resolution use 1.17 over 1.13.

How to expose swagger UI interface with jetty server and camel

I am doing a camel project with Jetty server using Springboot, I must expose the apis swagger-ui. I have already generated the swager in json format and it can be consulted at localhost:8080/swagger. Using swagger-ui webjars I am trying to see the graphic interface of swagger but this is not generated.
Im using this maven dependencies:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-swagger-java-starter</artifactId>
</dependency>
<dependency>
<groupId>org.webjars</groupId>
<artifactId>swagger-ui</artifactId>
<version>3.1.4</version>
</dependency>
<dependency>
<groupId>org.webjars</groupId>
<artifactId>webjars-locator</artifactId>
<version>0.36</version>
</dependency>
it is suppose that when using webjars the swagger-ui can be consulted in the path /webjars/swagger-ui/index.html, but i get:
Problem accessing /webjars/swagger-ui/index.html. Reason:Not Found
I tried to define a camel route like this: but doesnt work.
rest("/swagger")
.produces("text/html")
.get("/index.html")
.responseMessage().code(200).message("Swagger UI").endResponseMessage()
.to("direct://get/swagger/ui/path");
from("direct://get/swagger/ui/path")
.routeId("SwaggerUI")
.setBody().simple("resource:classpath:META-INF/resources/webjars/swagger-ui/3.1.4/index.html");
I was using this example:
https://medium.com/#bszeti/swagger-with-spring-boot-and-camel-ac59cca9556e
but I use Jetty as rest component
restConfiguration().component("jettty").port(8080).bindingMode(RestBindingMode.json)
.skipBindingOnErrorCode(false)
How can I expose the swagger Ui Interface?
I hope someone can help me, thank you very much

can not find addListener method from javax.servlet.ServletContext

I am trying to change spring xml settings to pure code based setting.
So I read official documents and some posts from blogs.
e.g. http://docs.spring.io/spring-framework/docs/4.1.x/javadoc-api/org/springframework/web/WebApplicationInitializer.html
An I made a code like ...
public class TestInitializer implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext container)
throws ServletException {
// TODO Auto-generated method stub
System.out.println("on Startup method has called.");
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(RootConfig.class);
container.
//container.addListener(new ContextLoaderListener(ctx));
}
};
A problem here. In those pages, they use addListener(new ContextLoaderListener(ctx)) method to set context. However my eclipse can not find that method from container variable.
I do not know any clue why my container variable(javax.servlet.ServletContext instance) can not read this method.
Thanks for your answer:D
P.S.
My spring version is 4.1.6.RELEASE and I include servlet3.0, spring-context, spring-webmvc on pom.xml.
========================
Maybe I got some communication problem, So I summarize this :D
javax.servlet.ServletContext doc clearly state that it has method
addListener >>
http://docs.oracle.com/javaee/6/api/javax/servlet/ServletContext.html
have to use Spring WebApplicationInitializer.onStartup(ServletContext) to set basic setting via Java source code, not XML
Can not load addListener from ServletContext class.
=================================
Edit. This is not error on console. However it is the only message I got.
It is from eclipse toolkit.
The method addListener(ContextLoaderListener) is undefined for the type ServletContext
than recommendation is Add cast to 'container'
To follow up on what #JuneyoungOh has commented, turns out that the problem is because of conflicting dependency. And these are the ways to solve this problem :
* make version 3.0.1 and artifactId 'javax.servlet-api' or
* add tomcat(in my case 7.0) to project build path and remove servlet dependency.
In my case the problem was because of Spring-Support which is depended on "javax.servlet" and I just excluded it:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-support</artifactId>
<version>${spring-support.version}</version>
<exclusions>
<exclusion>
<artifactId>servlet-api</artifactId>
<groupId>javax.servlet</groupId>
</exclusion>
</exclusions>
</dependency>
In my case there was:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
notice, that artifactId is servlet-api, not javax.servlet-api.
I have created a legacy MVC project, that's why I had this package. When I tried to convert .xml configuration to Java, I came across this problem.
Certainly it's not the same as in the question, but it shows up as the first result in google search.
In my case I just had to comment out the javax.servlet:servlet-api dependency as depicted here:
<!-- dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>7.0.47</version>
</dependency>
This looks like the same idea presented here: https://stackoverflow.com/a/30231246/2597758

how to handle multipart request using http client

Following is my code to handle Multipart using httpclient
if(methodParams.getDataType().length()>0 && methodParams.getDataType().equals("org.springframework.web.multipart.MultipartFile")){
isMultipart = true;
MultipartEntity entity = new MultipartEntity( HttpMultipartMode.BROWSER_COMPATIBLE );
// For usual String parameters
entity.addPart( methodParams.getVariableDefined(), new StringBody("".toString() , "text/plain", Charset.forName( "UTF-8" )));
postURL.setEntity( entity );
}
but i get the following exception :
Exception in thread "main" java.lang.NoSuchMethodError: org.apache.james.mime4j.util.CharsetUtil.getCharset(Ljava/lang/String;)Ljava/nio/charset/Charset;
at org.apache.http.entity.mime.MIME.<clinit>(MIME.java:51)

at com.hexgen.reflection.HttpClientRequests.handleHTTPRequest(HttpClientRequests.java:74)
at com.hexgen.reflection.HexgenWebAPITest.main(HexgenWebAPITest.java:115)
EDIT:
following are the dependency i use
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.0.1</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.0.1</version>
</dependency>
how to solve this.
You can take a look at dependencies one more time, perhaps you've missed some jars.
You may also replace your old jars with newer version of a httpclient along with httpmime. httpclient is no longer relying on james mime4j since version 4.1.
You may also end up managing your dependencies with maven. Just in case if you are not using it.
Edit:
You may add the following
<dependency>
<groupId>org.apache.james</groupId>
<artifactId>apache-mime4j</artifactId>
<version>0.6</version>
</dependency>

Problems with instantiating of HttpServletRequest with Mockito

The following line fails with an exception:
HttpServletRequest req = mock(HttpServletRequest.class);
Exception:
java.lang.ClassFormatError: Absent Code attribute in method
that is not native or abstract in class file
javax/servlet/http/Cookie
Has anyone faced this problem?
UPD
Solution was found here.
You should add implementation of Servlet API to your test/runtime classpath. I would suggest to use this dependency:
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.servlet</artifactId>
<version>3.0</version>
<scope>test</scope>
</dependency>

ClassNotFound exception using Jackson ObjectMapper

I have a Spring 3 MVC app that I am setting up some ajax actions for.
My controller action looks like this:
#RequestMapping(value="add", method=RequestMethod.POST)
#Secured("ROLE_USER")
#ResponseStatus(HttpStatus.CREATED)
public #ResponseBody Plan addPlan(#RequestBody Plan plan, Principal principal) {
//Save the plan
}
When I post the Plan data from my browser the app throws a ClassNotFound exception:
java.lang.ClassNotFoundException: org.joda.time.ReadableInstant not found by jackson-mapper-asl [176]
at org.apache.felix.framework.ModuleImpl.findClassOrResourceByDelegation(ModuleImpl.java:787)
at org.apache.felix.framework.ModuleImpl.access$400(ModuleImpl.java:71)
at org.apache.felix.framework.ModuleImpl$ModuleClassLoader.loadClass(ModuleImpl.java:1768)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
The Plan object itself does not contain any joda-date types. Though it contains a collection of objects that do. Originally I was pulling in the joda-date jar via my DOA jar but the error persists even if I add a direct dependency to my web project's pom.xml. I'm using the joda classes elsewhere in this project without any issue.
Additional information
Here are the relevant dependencies from my web pom.xml:
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>2.0</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.3</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.3</version>
</dependency>
I somehow came across this question: Apache FTP server is not seeing a logging jar package that exists in the class path
Their solution of setting <class-loader delegate="false"> in glassfish-web.xml seems to have fixed my issues.
I've reported this on Glassfish JIRA https://java.net/jira/browse/GLASSFISH-20808
