I found this discussion in Axis-dev mailing list. This is from last year. Does AXIS still implement DataHandler serializer that encodes the whole attachments into memory? Do you have any suggestions how can AXIS developers avoid this? Any comments/helps will be greatly appreciated. Best regards, Ignatia Subject: Re: Soap and Attachment- Huge data From: "Rick Rineholt" <[EMAIL PROTECTED]> Date: 2001-11-12 20:59:02 [Download message RAW] The SOAP attachments support is still work under progress. It's not functional from a Java service or client level. However, very preliminary measurements I have done on a local LAN using Tomcat 4.0 has shown zip files that are 60M have only taken roughly two minutes to send. I have tested once with a .5 G and that completed in a proportional time frame. The testing was done at what Axis calls a handler. There should be only a small amount of overhead between that level and the Java service and client API level. These are only a rough estimates and the work is far from complete. But there has also not been much performance tweaking done either. Rick Rineholt >The problem of big attachments with SOAP also bothers us.
