Hello, Since I didn't get any response I thought I should try again.I have created some Web Services with compressed attachments. The problem is on the server side, the zip file passed by attachment is locked by Axis and I can't delete it. I have looked at the thread "ttachment and closed stream question" (see "http://marc.theaimsgroup.com/?l=axis-user&m=109598153701095&w=2") but the solution is useful for the client side only.I tested it with AXIS 1.1 and AXIS 1.2RC1. I write the following code on my server :-----------------------------------------org.apache.axis.MessageContext msgContext = org.apache.axis.MessageContext.getCurrentContext(); org.apache.axis.Message msg = msgContext.getResponseMessage(); msg.getAttachmentsImpl().setSendType(org.apache.axis.attachments.Attachments .SEND_TYPE_DIME); ByteArrayDataSource bads = new ByteArrayDataSource(new File(zipFile), "application/x-zip-compressed"); DataHandler dh = new DataHandler(bads);org.apache.axis.attachments.AttachmentPart replyPart = new org.apache.axis.attachments.AttachmentPart(dh); msg.addAttachmentPart(replyPart);-----------------------------------------An yone have an idea?Thanks for helpFranck
