I can attest from experience that there is definately a limit in Apache SOAP in this regard. I am working on a SOAP xml-rpc based client/server application that needs to be able to send files between the client and the server. Whenever I tried to send the file along as a DataHandler or Inputstream, if the file was bigger than around 18 MB in size I would get a "Out of Memory Error" on the side trying to send the file.
My only way to get around this problem was to write a simple "browser" that could request files from the server and another that would perform an HTTP Post to a JSP running on the server so I could send. While this works, it circumvents our desire to use SOAP for everything and is a bit of a hack. The only thing I could come up with is that when you send structures like an Inputstream, Apache SOAP stores everything in memory as it's building up the envelope prior to sending it. As a result, large items eat up the Java heap space and a memory error occures. Sorry, wish I had better news... If anyone knows of a way around this problem other than what I've outlined, I'd love to hear it! --Mike ----- Original Message ----- From: "WJCarpenter" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, October 28, 2002 1:22 PM Subject: RE: A question about SOAP with attachments! > > Theoretically, there's no limit.
