File name check during a BPM.

Question

Hi All,
Can we configure the file sender/receiver adapter to just check whether a file with a particulat file name exists in a directory?
I want to do this check at a particular stage in BPM. If the file name is detected, I would like to proceed in a BPM.
Kindly assist.
Thanks,
John

Hi John,
You can use this code in the udf if the file directory is in the local file system
public String fileExists(Container container) throws StreamTransformationException{
   String FilePath = "C:\\FileName.txt";
   String reslt = "false";
   File f = new File(FilePath);  // You can even get this FilePath through function parameter as var1
   if(f.exists)
      reslt = "true";
   else
      reslt = "false";
   return reslt;
The function will return a string "true" if the file exists and "false" if not.
