title: Java web services to allow large file streaming
body: <p>I am building a java web services server that needs to scale and to be highly available. User can upload large file (~20M) through the services. SOAP is preferred. </p>
  
  <p>My question are: is there any such a web service framework which support large file streaming? Any building blocks that I should consider? Any good practices? </p>
  
  <p>Any thoughts would be appreciated. Thanks.</p>
