attachments not getting stored.

[Krthekeyan Suriyanarayanan]

HI all,
I am trying to send attachments through webservice , When I try to 
figure out the receipt of attachment file . I am getting the data from 
client, but the file is not getting
stored in the attachment.directory which i had mentioned in config file. 
what could be the problem. I suppose the files has to automatically 
store in that particular directory right.
what could be the problem.

Next thing is I wanted to implement securiy on this service also. where 
can i refer.

thanks,
