    java.io.EOFException when using Multipart form-data

    Adrian Boangiu Newbie

      Hello,

       

      We have migrated an application developed using ADF 12.1.3 and ADF Faces based on Trinidad implementation from JBoss 7.1.1 to Wildfly 10.1.

      In Wildfly 10.1 we have the following exception every time we post a form which allows multipart content:

      We have observed that at the level of the method org.apache.myfaces.trinidadinternal.share.util.MultipartFormHandler._skipBoundary:

       

      public MultipartFormHandler(final String type, final InputStream in) throws IOException

      {

      if (!type.startsWith(_MULTIPART_REQUEST_TYPE))

      {

      throw new IllegalStateException(_LOG.getMessage(

      "CONTENT_NOT_MULTIPART_FORM_DATA"));

      }

       

      _boundary = _parseBoundary(type);

      _in = new BufferedInputStream(in);

      _skipBoundary();

      }

       

      the InputStream in contains the full text of the http request in JBoss (and Tomcat) and is empty in Wildfly.

      Can you please tell us if there is something we can do to overturn this error?

      Thank you

          it  happens always or just if file is bigger than certain size?

            It happens always with or without file to transfer. All our forms have the possibility to upload files. But when the form is posted even without a file to upload we get the exception.

              In the example I have provided there is no file to upload.

                  Do you use Apache Trinidad in your application too? Can you add more details including the complete exception stacktrace that you see?

                    yes we are using Trinidad 2.1 version. Below is the exception trace-

                      This very much looks like an issue within the Trinidad library code. You might have to raise this issue in their user/dev forum/mailing list.

                        I do not think it is Trinidad library issue as i have tried using Tomahawk file upload component as well as jboss seam 2.3 [wildfly 10 compatible seam version] file upload component. The component value in all cases is submitted as null.

                          I actually take that back. This may not entirely be Trinidad library's issue. Looking at Trinidad's code and Undertow code, what seems to be happening here is that Undertow, during request authentication (backed by FORM mechanism) parses the multipart form data, request stream and then hands off the request to Trinidad. Trinidad notices that it's a multipart form data and tries to parse it by itself to find uploaded files and since the stream has already been parsed by Undertow, there's nothing left in there, which is what causes this EOFException.

                           

                          Looking at Trinidad's file uploading component code, it does have hooks to skip that processing. What you need to decide is whether you want Trinidad's file upload component to handle your uploads or whether you want Undertow to do it. Right now, there's no formal way to skip this default parsing of the form data in Undertow if FORM based authentication is used, so you might have to disable the file upload component of Trinidad (the details to do that might/should be available in Trinidad's documentation).

                            Thank you for your help. Will check the Trinidad documentation and try that.

                              You were right. Commenting the Trinidad filter  [which is responsible to handle file upload] in web.xml resolved the issue. However,  not sure if not having this filter will have impact on any other Trinidad component.

                                It will actually have an impact on other Trinidad components, based on what I see in the code of that filter.

                                 

                                Given that you and the original poster in this thread seem to indicate this wasn't an issue in previous version of JBoss AS, I would like you see what your application looks like. Does it involve FORM based authentication? Can you attach a sample application which reproduces this and steps to reproduce it?

                                  Yes our app does the form based authentication.  I do notice after removing the Trinidad filter, first thing that started to fail is  where the character encoding is fetched from the request. It started giving the NULLPointer exception. Trinidad filter fetches the encoding from  the header' s "content type"  parameter and sets it in the HttpRequest object. As we have a custom filter in our application, i have added Trinidad's code in our filter [only the part to fetch and set the encoding] and things are working for me.

                                   

                                  The simplest way to reproduce it is to deploy Trinidad's 2.1 component demo application to wildfly 10.1  and access the inputfile component UI.
