You may already realize this, but I believe this is what is happening: You have an action defined to use the stream result type. The stream result requires an InputStream to be available on the stack when it starts processing. This is usually provided by a getInputStream() method on the action. When, getInputSteam() returns null, Struts continues to look up the stack to try and find the InputStream to stream to the client. When it can't find it, it throws the exception you are seeing. I think you should look into what conditions could allow your getInputStream() method to return null (and probably log the heck out of those situations). (*Chris*)
