Re: FileUpload via Http

Wed, 22 Mar 2006 06:44:25 -0800 

Thanks Guillaume,
I have tried using the HttpComponent, but it threw an exception in the DeliveryChannel and ReceiverComponent. My client code is the following: 

     File f = new File("some_file.txt");

     PostMethod filePost = new 
PostMethod("http://localhost:8192/Service/";);

     Part[] parts = { new StringPart("param_name", "value"),
         new FilePart(f.getName(), f) };
     filePost.setRequestEntity(
         new MultipartRequestEntity(parts, filePost.getParams()) );
     HttpClient client = new HttpClient();
     int status = client.executeMethod(filePost);
     filePost.releaseConnection();

and my XmlBeans configuration file is the following

     <sm:activationSpec>
         <sm:component>
           <http:component>
               <http:endpoints>
                   <http:endpoint service="test:MyConsumerService"
                                              endpoint="myConsumer"
                                  role="consumer"

                                  
locationURI="http://localhost:8192/Service/";
                                  
defaultMep="http://www.w3.org/2004/08/wsdl/in-only"; />

               </http:endpoints>
           </http:component>
       </sm:component>
     </sm:activationSpec>

    
     <sm:activationSpec service="test:MyConsumerService" 
endpoint="myConsumer">

       <sm:component>
         <bean class="org.apache.servicemix.tck.ReceiverComponent" />
       </sm:component>
     </sm:activationSpec>

and I get the following exceptions

The servicemix-http component handles MIME attachments.
You should give it a try.

Hello all,

I am trying to include a file upload facility using http within my
project. Unfortunately, my file is not an xml document, so it should be
treated as an attachment. If I am correct, the HttpMarshaler only
accepts xml documents which are set to the message content. Would there
be a way to accept non-xml files and set them as message attachments
(similar to the SaajMarshaler)? Or is there another, more elegant way of
doing this?

Thanks,
Stefan
