Need to get the file name at the time of polling

Question

Hi...
I am transferring the data from csv file to database.
I put the file in a directory. File adapter will read that file for every 2 minutes. I have a column name in database to which I need to map the incoming file name.
Here my requirement is: how can I get the name of the csv file dynamically at the time of polling, so that I can map the file name to corresponding column name in database. Is there any special mapper function in Jdeveloper component palette to do it or can we do some thing with the file adapter to achieve this.
Thank you very much...any help is appreciated.

This is a very simple task in JDeveloper 11g, file adapters are linked to the receive activity, here there is a tab called Properties which you can use to extract the file name. Please follow the steps below:
1. Create a Simple Type variable of string type, call it fileName_var or any name you wish.
2. Open the Receive activity in your bpel project.
3. Scroll down to jca.file.FileName and double click on the value column, click on the browse button (...), select Variable, then click the search icon
4. Locate your recently created variable
5. Now when your project runs it will assign the file name to this variable, you can use this same approach also to pull the directory, file size, etc.
Please note, that you may see a warning little icon on your project saying variable is not initialized, this is perfectly ok and it does not represent any issues when deploying the project.
Hope this helps.
