Message body reader not found for multipart/form-data - Un Supported media type(415) Error

Question

Below is the signature of my webservice method that accepts attachment with it's content-type = multipart/form-data

@POST  @Path("/saveimg")    
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response saveAttachment( @FormDataParam("files") InputStream fileInputStream,
             @FormDataParam("files") FormDataContentDisposition contentDispositionHeader) {

I got the following error:

SEVERE: A message body reader for Java class com.sun.jersey.core.header.FormDataContentDisposition, and Java type class com.sun.jersey.core.header.FormDataContentDisposition, and MIME media type multipart/form-data; boundary=----WebKitFormBoundaryiNkfu0uRssIuZMPX was not found. The registered message body readers compatible with the MIME media type are: / -> com.sun.jersey.core.impl.provider.entity.FormProvider com.sun.jersey.core.impl.provider.entity.StringProvider com.sun.jersey.core.impl.provider.entity.ByteArrayProvider com.sun.jersey.core.impl.provider.entity.FileProvider com.sun.jersey.core.impl.provider.entity.InputStreamProvider com.sun.jersey.core.impl.provider.entity.DataSourceProvider com.sun.jersey.core.impl.provider.entity.XMLJAXBElementProvider$General com.sun.jersey.core.impl.provider.entity.ReaderProvider

When I changed the consumer content-type to @Consumes("application/x-www-form-urlencoded") the above error log disappears but server 415 ( Un Supported Media Type) persists. The request sent has content-type multipart/form-data including boundary along with mulitipart/form-data. — Yergalem

For some reason, I'm not using Maven. Can you tell me what is missing? — Yergalem
it seems you need to have the jar for multipart. Are you using glassfish libraries? — Wilder Valera

try to remove FormDataContentDisposition, I removed it and now I don't have 415 error... but I have to find an other way to get the information needed.

my file here:@FormDataParam("file") InputStream fileStream.

I tried to read file like that:

final Reader reader = new InputStreamReader(fileStream); String text = CharStreams.toString(reader);

but not my final solution... i'm looking for other solution... hope I could be helpfully.
