Suggessions required for File----XI----Idoc Interface

Question

Dear All,
I have developed File-XIIdoc Interface and works fine.
Query: When the Source application is trying to write the data into file, XI needs to wait until it completes
Once the writing is completed then only XI has to pickup the file from Source location.
If XI is not checking this check point, File adapter is picking up the file in the middle of the data writing itself.
Please suggest me your thoughts and experience on this

Hi Suman,
For writing a module please check the blog and articles in SDN.
The module logic should be as follows:
1. it should read and store intermeidiately the size & filenam of all files present in the folder.
2. do a wait of say 30 sec in the module (by sleep or any other such waiting command of java).
3. Then recheck the size of only those files read in step one (don;t read entire files present in folder now as some new files may have been created in this 30 seconds sleep time)
4. If the file size changes don't do anything else send the content to PI and /archivethe file (should be done inside the module code)
5. Keep the file sender channel in Test mode (as the module will do the necessary archival/deletion)
