Upload File with webservice

I want to upload a file to sharepoint without using the API or a custom webservice.  I have tried to use Copy.CopyIntoItems() to upload files, but when the destination is in the "Meeting Workspace", it's failed and I got the error "The destination is in a Meeting Workspace, which does not support this action." 
I know I can user HTTP PUT to do that, but is there any other method to upload files to any specified document library with sharepoint webservice?
