RE: RUNJVA problems

Basically he is telling you that when you run your program on a Windows 
machine, Windows is taking care of the fact that your path convention is CIFS 
specific (it's call an UNC). When you run this program on a System i, 
FileReader doesn't know how to open a file using the path you've specified 
because the i5/OS uses IFS paths not CIFS. You can get JCIFS and use that to 
open files on Windows shares from the System i and it uses URL naming 
conventions like Thorbjørn mentioned. You can get JCIFS at 
http://jcifs.samba.org/ and they have any number of examples that could be 
useful to you.

Thanks for the reply.  

The RGC_AD is a windows server. 
I'm not sure I totally understand what you mean here. 
--FileReader basically uses the underlying operating system to resolve the 
--name.  The path you have used in your code is Windows specific (and 
--refers to a file on the RGC-AD machine), and is not valid on a 
--non-Windows host.

--If the file is located on the AS/400 you should identify its local name 
--and use that instead.

--If the file is located on another host, you need to use code that knows 
--that.  E.g. JTopen knows how to talk to a remote AS/400.

--In case this is a frequent scenario you might want to start use an URL 
--to refer to your files.  This allows you to use many different protocols 
--to access them, and to provide your own in case you have a very frequent 
--and cumbersome task.

Can you provide me with an example?  

Java class resides in IFS, being called from CL program, accessing a file on a 
windows server. 

Thanks.

My problem now is that I'm referencing a file in my class, but I'm 
getting a 'No such path or directory' error.
I know that the path is valid, because I can run successfully within
WDSC.  
  

On your Windows machine?

BufferedReader in = new BufferedReader(new 
FileReader("\\\\rgc-ad\\Public\\customer Service\\Lockbox\\Lockbox 
Payment Datafiles\\020707P.txt"));
  

FileReader basically uses the underlying operating system to resolve the 
name.  The path you have used in your code is Windows specific (and

non-Windows host.

If the file is located on the AS/400 you should identify its local name

If the file is located on another host, you need to use code that knows
