Hi Pablo, sorry for the delayed response.
From looking at the stack trace, it appears the problem is caused
either by locked files or bugs or inconsistencies in UnixFileDirectory. Let me explain.
In MaObjectFiler>>#open, Magma asks the UnixFileDirectory
directory exists and: [ directory fileExists: self class objectsFilename ]
and the system reported true for this, otherwise it would have stopped you right there with a MagmaEnvironmentError.
Under this assumption, Magma then proceeds to open the object file. FileDirectory>>#fileNamed: is used to create the FileStream which is required by Magma. Unfortunately if some problem occurs, FileDirectory>>#fileNamed: doesn't signal a meaningful error, it only answers nil. Since we just checked fileExists: its not because it doesn't exist so is it possible the files are "locked" by another process or something? Did they get closed after the upload?
Otherwise, there may be some bad inconsistency with UnixFileDirectory>>#fileExists: and UnixFileDirectory>>#fileNamed:.
I'm no Unix expert, anyone else have any ideas?

Hi all,
I'm deploying a small seaside application that uses magma to store objects. I did it in win2k.
When I try to create the repository I got an error because seasidehosting uses a modified version of the VM with some sort of issue in the SecurityPlugin that dont let me do that. (this part isn't related to Magma but I wrote it to put as in context )
So I tried to create the repository in my win2k and then upload it to the server.
When I startup the application I got an error (I included the stack trace at the end of the message and attached the blank repository I'm trying to use).
Does anybody knows what I'm doing wrong and why I couln'd use the repository created with win2k in linux?
Thanks! Pablo.-
I set WAMagmaConfiguration's Repository Location to '/service/edp/files/magma' (as seaside suggested). I'm using the Sq3.8f+seaside+magma image.
