Question

After upgrading from Resteasy 2.4 to 3.0.5. my file upload is no longer working. Here are the relevant bits.

The interface:

  @POST
  @ClientResponseType(entityType = JAXBModule.class)
  @Path("/upload")
  @Consumes(MediaType.MULTIPART_FORM_DATA)
  @Produces(MediaType.APPLICATION_XML)
  public Response upload(@MultipartForm FileUploadForm form);

The FileUploadForm class

public class FileUploadForm {

  @FormParam("file")
  @PartType(MediaType.APPLICATION_OCTET_STREAM)
  private InputStream data;

  @FormParam("user")
  @PartType(MediaType.TEXT_PLAIN)
  private String user;

  @FormParam("password")
  @PartType(MediaType.TEXT_PLAIN)
  private String password;

  @FormParam("filename")
  @PartType(MediaType.TEXT_PLAIN)
  private String filename;

  public FileUploadForm() {
  }

  public InputStream getData() {
    return data;
  }

  public void setData(InputStream data) {
    this.data = data;
  }

  public String getUser() {
    return user;
  }

  public void setUser(String user) {
    this.user = user;
  }

  public String getPassword() {
    return password;
  }

  public void setPassword(String password) {
    this.password = password;
  }

  public String getFilename() {
    return filename;
  }

  public void setFilename(String filename) {
    this.filename = filename;
  }

The client:

ResteasyClientBuilder rsb = new ResteasyClientBuilder();
ResteasyClient rsc = rsb.build();
ResteasyWebTarget target = rsc.target(BASEURL);
ModuleArchiveService client target.proxy(ModuleArchiveService.class);
FileUploadForm upload = new FileUploadForm();
upload.setUser("joe");
upload.setPassword("pwd");
upload.setFilename("image.jpg");
String fileToUpload = "testdata/image.jpg";
upload.setData(new FileInputStream(fileToUpload));
Response response = client.upload(upload);

The error message:

I have resteasy-multipart-provider-3.0.5.Final.jar in the class path. I am using Java 7 and Tomcat 7.0.42

Was it helpful?

Solution 2

Apparently this is a very well know bug, see https://issues.jboss.org/browse/RESTEASY-954. I am hoping it will be indeed fixed by the next release in the new year

OTHER TIPS

Do you have jaxrs-api-3.0.5.Final.jar in the class path?
