This might be similar to a problem we faced some time ago.
Getting a ('non-small') file from the server two times in a row makes
the client program hang on the second file. This affected all methods
that transferred files from server to client using Axis and Java
DataHandler.
Getting a very small file (a few bytes) inbetween the two previous calls
and everything works.
Running TCPMonitor on the server-client communication showed that the
request call from the client that comes AFTER a getFile() call contains
the previously received attachments! It turns out that the automatically
generated code from the wsdl2java erroneously calls setAttachments()
using the attachment of the previous call!
In other words: the error was in the client side
<MyService>SoapBindingStub.java that Axis/wsdl2java generated for us.
(or we were using the generated code erroneously... :-) )
Commenting out the setAttachments() and extractAttachments() in all
methods in <MyService>SoapBindingStub.java in the client solved this
problem for us.
Good luck!
