Use a Constant actor, not a String Constant actor.
Constant will interpret the contents as a variable unless it is inside
double quotes, in which case it is a string
StringConstant will interpret the contents as a string.
If a Constant actor has the value wrapped in double quotes:
"AString"
then the output will be a string with the value AString
If a Constant actor as the value
AString
The the output will be the value of the parameter named AString
If a StringConstant actor as the value
AString
Then the output will be a string with the value AString.
BTW - for future reference, this is better off sent to Kepler-users than
Kepler-dev. The question is about using Kepler, not modifying the Java
code. No worries on this.

Hi Scott,
I appreciate your help. but I still have a problem.
It seems like it is working because I do not have any error message.
but I could not see the output file as in the directory I used. See my
screenshot attached.
Thank you

Donghoon,
You can use a File Parameter and a Constant actor to accomplish your
goal. Type the name of the File Parameter in the Constant actor and
connect it to the fileToWrite port on the Text File Writer Actor.
Sorry,
I can't easily create and attach and example, but detailed steps
follow.
Scott
1. Drag a FileParameter onto the canvas
2. Double click on FileParameter and specify the path to the file you
want to write
3. Right click the FileParameter and select Customize Name
4. Type MyFileParamter in for the name field and click Commit
5. Drag a Constant Actor on the canvas
6. Double click the Constant actor and type MyFileParameter on the
line
next to "value:"
7. Connect the Constant actor to the fileToWrite Port on the Text File
Writer
