Multipart message empty in servlet

[Mark Lawson]

Hi,

I’m having a problem getting a multipart-mime uploaded file from the servlet 
component using Commons FileUpload.
I’m using Camel 2.12.2 with Tomcat 7.04 using the camel-example-servlet-tomcat 
with added groovy.
What happens is I can parse the stream and get the headers, but the body seems 
to be empty i.e. boolean nextPart = multipartStream.skipPreamble(); always 
returns false.
Any ideas? My groovy code is below less the imports.


                        def mybody = 
exchange.getIn().getBody(InputStream.class);
                        def content_type = 
exchange.getIn().getHeader(exchange.CONTENT_TYPE,String.class);
                        
                        //Get the mime boundary string
                        int lastIndex = content_type.lastIndexOf("=");
                        String boundary = content_type.substring(lastIndex+1, 
content_type.length());

                        //Send the stream and the boundary to the parser
                        MultipartStream multipartStream = new 
MultipartStream(mybody, boundary.getBytes());                     
                                        
                        response = "Headers. " + multipartStream.readHeaders(); 
        
                        boolean nextPart = multipartStream.skipPreamble();
                        response += “ Is there a next part? “ + nextPart ;
                        while(nextPart) {
                                // Do something here
                                nextPart = multipartStream.readBoundary();
                        }
                        response;       

I’ve tried this with both caching on and off without any success.
