MQSeries.net :: View topic - Txt File Empty with FileOutput Node (IIB 9.0.0.2)

Hi Everyone,

I'm developing an application that receives a DataObject from a MQ Queue. In my flow i'm building a semicolon-delimited String that i want to write in a txt file with FileOutput Node.

My Flow is:

MQ Input (DataObject Input Parser) -> Compute (Logic for build the string) -> FileOutput Node

I've tried with this approaches and i'm getting the same result: the file is written but it's empty:

1. Store the string in Environment.Variables.XXX (XXX is the container of this data, Character defined). This path is configured in FO node.
2. Create a DFDL Message model to parse the data, only having one variable (the string that i want to store). Write the data in Root.DFDL and point the FileOutput Node to this location.

None of above has worked and i didn't found anything (here, DW, IBM Documentation) about this issue.

Other things:

1. The filename is dynamic and i'm using LocalEnvironment to set the FO properties, without problem.
2. I have double checked permissions in the folder, granted all access to the OS user (I'm on Windows 7) and it's the same: the file is written but without content.
3. I've changed the Data Location to $Root/DataObject (original data retrived) and in this case the node writes the content of this context (in a XML manner).
4. I only need one record per file (the option that i'm using is "Record is whole file").
5. Compute node has the "LocalEnvironment and Message" computing option.

What i am doing wrong? I'm forgetting something?

I appreciate some light on this...
