> Hi, all
> Our software(Client for Web Service) calls Web Service which returns
> MIME Attachment with Stub generated by WSDL2Java.
> While the client had held DataHandler acquired from the response is
> called, if the client calls web service using same Stub instance, client
> CAN NOT access to the InputStream in DataHandler.
> (InputStream throws IOException of "resouceDeleted.")
> I investigated the source, and confirmed InputStream becomes invalid in the
> following flow.
> 1. 
> At this line of each Stub methods,
> "extractAttachements(_call);"
> (after "Object _resp = call.invoke(xx);"),
> Stub holds attachments in response.
> 2.
> Stub adds to the request in next "setAttachments(_call);".
> 3.
> When HttpSender outputs the requests to the stream, Massage calls
> "AttachmentsImpl#writeContentToStream()".
> 4.
> AttatchementImpl calls ManagedMemoryDataSource#delete(), then
> InputStream becomes invalid.
> I also saw these bug reports.

> However, I cannot understand why Stub adds the Attachment of response to
> the next request, and I have no idea how I should avoid.
> Please advise me.
> Thank you.
