I am using Jersey based restful Service implementation strategy to build a service which will be used to upload files. My service class name is : UploadFileService.java (See Code below)
package com.jerser.service;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;
@Path("/fileUpload")
public class UploadFileService {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
These are the JAR files I have inside my lib:
aopalliance-repackaged-2.4.0-b10.jar asm-debug-all-5.0.2.jar hk2-api-2.4.0-b10.jar hk2-locator-2.4.0-b10.jar hk2-utils-2.4.0-b10.jar javassist-3.18.1-GA.jar javax.annotation-api-1.2.jar javax.inject-2.4.0-b10.jar javax.servlet-api-3.0.1.jar javax.ws.rs-api-2.0.1.jar jaxb-api-2.2.7.jar jersey-client.jar jersey-common.jar jersey-container-servlet-core.jar jersey-container-servlet.jar jersey-core-1.11.jar jersey-guava-2.17.jar jersey-media-jaxb.jar jersey-multipart-1.18.jar jersey-server.jar org.osgi.core-4.2.0.jar osgi-resource-locator-1.0.1.jar persistence-api-1.0.jar validation-api-1.1.0.Final.jar
I am getting the following error when I am trying to up my tomcat server :
org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.

Over the internet I found there are plenty of example which shows How to upload MULTIPART file using RESTFul API. But with same solution. I am not able to run those code as well. I think I am doing something wrong with the JAR files. Could anyone please help me on this?
Get rid of jersey-multipart-1.18.jar. That is for Jersey 1.x. Add these two
For Maven you would use the following dependency (you don't need to explicitly add the mimepull dependency, as this one will pull it in).
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.17</version> <!-- Make sure the Jersey version matches
the one you are currently using -->
</dependency>
Then you need to register the MultiPartFeature. If you are using a ResourceConfig for configuration, you can simply do
register(MultiPartFeature.class);
If you are using web.xml, then you can add the class as an <init-param> to the Jersey servlet
<init-param>
<param-name>jersey.config.server.provider.classnames</param-name>
<param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>
Note that if you have multiple providers that you want to register, then you can delimit each provider class with a comma, semicolon, or space/newline. You cannot use this same param-name twice. See Suarabh's answer
UPDATE
Also, once you get rid of jersey-multipart-1.18.jar you will have compile errors for the missing imported classes. For the most part, the class names are still the same, just the packages have changed, i.e.
org.glassfish.jersey.media.multipart.FormDataParamorg.glassfish.jersey.media.multipart.FormDataContentDispositionIf you're using Dropwizard, instead of adding the jersey-media-multipart, they document for your to add dropwizard-forms instead. And instead of registering the MultiPartFeature, you should register the MultiPartBundle
@Override
public void initialize(Bootstrap<ExampleConfiguration> bootstrap) {
bootstrap.addBundle(new MultiPartBundle());
}
Really doesn't make much difference though as all the Dropwizard bundle does is register the MultiPartFeature with the ResourceConfig.
If you are here for a different ModelValidationException, here are some links for information on other causes of the exception.
