Hi,
We have a well working file transfer service that works with files up to approximately 2.1 GB (probably Integer.MAX_VALUE: 2147483647 bytes?). When transferring even larger files, Axis2 fails with the following message: org.apache.axis2.AxisFault: Referenced Attachment not found in the MIME Message. ContentID:1.urn:uuid:[EMAIL PROTECTED] What happens is: The client transfers the complete file to the server. The server correctly caches the file in the attachmentDIR folder. The AxisFault is thrown. The server-side cached file have the exact same byte-length as the file the client sent, so every byte has been transferred. I am currently using Windows XP with NTFS and support for files much larger than 2.1 GB on both sides, Axis2 1.3, document-literal style, ADB, MTOM and caching to disk. Any ideas? The DataHandler that is supplied to the client stub is generated like this: FileDataSource datasource = new FileDataSource(localFile); dh = new DataHandler(datasource); Parts of my Axis2.xml file: <parameter name="enableMTOM">true</parameter> <parameter name="enableSwA">false</parameter> <parameter name="cacheAttachments">true</parameter> <parameter name="attachmentDIR">C:/TEMP/da_server_temp/</parameter> <parameter name="sizeThreshold">50000</parameter> Regards, Roy Willy Haug
