I've not done this, but I think using attachments would best -
it would be possible pass the CSV inside an XML document in the SOAP body, but would that would require extra work, making it more complicated and slower.

SAAJ is the J2EE API that lets you do SOAP with Attachments (SwA) - search for documention on that.
