If you use special characters such as ( ) in "fromFilename" field in CopyFile activity, then you will see the following exception.

java.util.regex.PatternSyntaxException: Unclosed group near index 13

Issue/Introduction

Using special characters such as ( ) in "fromFileName" of CopyFile activity.

Resolution

Use Character class from regex Pattern and surround the special characters with [ ] like the following:

Actual Input : C:/tmp/file(name).txt

Correct Input as per Regex : C:/tmp/file[(]name[)].txt

This is needed as BW uses regex to parse the input file name for CopyFile activity.
