I have a simple java application to upload files to sharepoint over WebDav. This works fine when uploading Picture and Word Doc libraries. However, it fails with HTTP/1.1 409 CONFLICT when uploading to Customized Reports and Form Templates libraries. Is there any particular reason for that?

  • Both Customized Report and Fomr Templates are Base Type set to DocumentLibrary so there no difference in terms of Base Type.

The only thing I can think of is that you may have multiple requests out there stepping on each other, thus giving you your 409 error. But, i'm not a DEV so I may be off base.

The form library extends the base doc library to work with XML files, so the communication path may be changed. I would load up FIDDLER / FIREBUG and watch what is happening. That would also tell you if multiple requests are going out or something else funny.
