Hi Supun
I am trying to upload a file to the database in the form of a blob during
which the file upload program writes a temporary file to the disk.
It seems though the Stratos app server is preventing such temp file to be
written to the disk due to security reasons. I have attached the stack
trace of the error. Would you be able to help us in solving this problem?
We however cannot avoid writing temp files, so that’s something we have to
live with. There are other places in the our application where we require
writing temporarily to disk.
So the only way this could be solved is by adjusting i.e. modifying the
security manager setting in Stratos ?.
Is this possible (I guess this should be), if YES how? It would nice if
you could send us some links on how this problem could be circumvented as
there aren’t that many posts on this particular problem.
this is the file-upload class http://paste.org/47685
