Java Programming

When tomcat as a service runs, it cannot access network shared directory that is mapped to a drive letter Z.

I have tried the following:
- I have set the service to run as a Local system user
- I have set the service to run as a normal user
- I set the application to use UNC path to the network shared directory. Also since that when mapping a drive letter the shared directory requires a user name and password to read its contents, I donot know how the service can give these credentials automatically.
- I have set a login script for the user to run at start up that maps the directory Z drive. The script basically contains this command:
net use Z: \\10.29.168.22\qdir\files /user:qfileuser qfileuserpassword

When the application is run from eclipse or command line (not as a service ofcourse) it can access the drive.

The same problem is posted on this thread but with no working solution (or at least for me)

Anyone has had the same problem and solved it, any suggestions on this would be useful as well.

Thanks.
