Hello everyone:
I'm pretty new to the message broker development world and was wondering if WMB has the ability to create folders on a shared network drive. Ideally, the name of the folder would come from a value within the incoming XML file.
Does anyone have an example they can share?
Thank you,
-Brian

Hi Brian.
Yes, WMB can do this. WMB is a container, and operates a number of languages in the container much like WAS or Tomcat are containers.
To create a folder on a network drive from WMB, first verify that the system you are using has ability to access the network share and that the WMB Service Id has authority to write to that directory (WMB service Ids should never be 'mqm').
Next create a Java compute node that has the following:
| Code: |
import java.io.*;
public void createdir()
{
try{
String strDirectoy ="test";
String strManyDirectories="dir1/dir2/dir3";
// Create one directory
boolean success = (
new File(strDirectoy)).mkdir();
if (success) {
System.out.println("Directory: "
+ strDirectoy + " created");
}
// Create multiple directories
success = (new File(strManyDirectories)).mkdirs();
if (success) {
System.out.println("Directories: "
+ strManyDirectories + " created");
}
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
|
Good luck.

By the way, FileOutput cannot create a folder on a remote FTP server. Does anyone know if this has been fixed? I made a PMR for a customer a year or two ago but I'm under the impression that nothing was done. |

Quite so, but the OP was talking about a shared drive.

You would be best advised to look up the PMR number. As I indicate above, my belief is that it still doesn't work.

Hi Vitor,
Could you share the link to the documentation that describes how to implement this with FileOutput node? I tried to find it from InfoCenter with no luck. Perhaps it was just because of my inability to use right keywords.

Marko, I think Vitor just means the one line you need for overriding $LocalEnvironment/Destination/File/Directory
Of course you will have to write a file in the directory, too, for this to work.

I'm not working at that client any more. I asked them for the PRM number but they have not replied. |

I made the simplifying assumption that if you're not writing a file to it, you don't care much if the directory's there or not.

Yes it does, paragraph LocalEnvironment.Destination.File fields. So basicly you just
| Code: |
| SET InputLocalEnvironment.Destination.File.Directory = '<some directory path>'; |
But if for example the input message already contains the directory path, you do not need to copy it to LocalEnvironment, you just set the FileOutput node property Request directory property location to point to the correct field as documented in FileOutput node documentation.
What may have confused you is that I copied the path from FileOutput node documentation where Request directory property location uses slash as path separator. I should have put it this way:
Marko, I think Vitor just means the one line you need for setting LocalEnvironment.Destination.File.Directory |

Thanks Esa,
I must need either new brains or glasses ;-) but where does it say that by setting this LocalEnvironment.Destination.File.Directory -variable FileOutput node will create the folder to file system if it doesn't exist already?

Yes,
I tested and it works with 6.1 and 7 ;-)
| Code: |
SET OutputLocalEnvironment.Destination.File.Directory = '/home/xx/filenode/test';
SET OutputLocalEnvironment.Destination.File.Name = 'test.txt';
where folder structure .../filenode/test didn't exist before writing test.txt with File Output node
|
does the trick.
