Hi all,

I'm not sure if this is the right forum, so if it's not then please move to the appropriate section.

My java application is running on Tomcat 6 in a Linux environment. The linux environment has a mapping to a windows server, using Samba. We've called this mapping W.

In my prpoerties file which I call to read files from the windows server. The entry I have is as follows:

REPOSITORY_PATH=//W/PLANNING

PLANNING is a subdirectory on the windows server.

The problem is that everytime i go to read a file from my repository I get a file not found error.

What do I need to configure to get around this?

Andy help greatly recieved as I'm shooting in the dark right now as Samba was installed by an external company

Thanks,
Terry

What's the exact error message? Does it mention something about a login or password? If so you can try to use JCIFS; also check this thread.

Hi Rob,

No I just get a plain old java.io.FileNotFoundException error, with not much else to go on

There's no message after the exception name? What's the entire stack trace?

Is Samba part of the equation? Can you access files external to Tomcat but on a local drive?
The reason I ask is because Tomcat on Ubuntu Server is installed with the security configuration locked down such that it can only access files under the webapps directory. If you cannot access external files, check the settings in your $TOMCAT_HOME/conf/catalina.policy.

Yes, Joe, Samba is part of the equation. I have no problem accessing files outside the tomcat instalation. I'll check those settings. Thanks for the clue

*nix machines don't have drive letters with a colon. You should be using the name of the server as the root of the path followed by the share name.
