Re: Writing to QDLS with Java on the 400

["Dave Wall" <dawall@xxxxxxxxxx>]

Sorry, QDLS is not thread safe so threaded jobs cannot access it.  Java
jobs are automatically threaded so java.io.* classes cannot access files in
QDLS.

I know this is going to be a big surprise, but I am going to suggest a
Toolbox class :-).  The Toolbox IFSFile* classes access data via the file
server which is single threaded so they can access files in QDLS.  With a
small amount of code change you can use Toolbox classes instead of java.io.
* classes.

Is there any truth in the rumour that you can't use Java with the QDLS
filesystem?  We have to support a legacy system that picks up files from
there; our application just uses standard Java classes to create files
in a specified directory, like /home/user-name under Unix, or
C:\some-dir under Windows.

But when we specify /QDLS/AFOLDER on the AS/400, we invariably get an
exception saying "Folder not found" (it does exist).  It works perfectly
well if we use another filesystem, like /QOpenSys/some-dir.

I haven't been able to find anything official about this, but a web
search did lead me to an AS/400 zip application written in Java, which
claimed that, "Java doesn't work with QDLS".

Does anyone know the truth?

Cheers,

Martin.
