Execute Process Task error

As part of SSIS package I created a Execute Process Task that executes a batch file, however  the process fails to execute correctly and returns the following error;

[Execute Process Task] Error: In Executing "C:\Program Files\screen-scraper basic edition\ercot_run.bat" "" at "", The process exit code was "1" while the expected was "0".

I can execute to batch file manually and it works fine. I have set the batch file’s directory to allow everyone and I have tried changing the task’s properties to ignore failures  e.g.   MAxiumErrorCount = 1 , FailTaskIfReturnCodeIsNotSuccessfulValue = False

The batch file contains the following code;

"jre\bin\java" -jar screen-scraper.jar -s "mospublic.ercot.com"

Additionally, I cannot get the batch file to execute in windows task scheduler either.

Any suggestions as possible solutions to this problem?

Thanks
