How to run a batch file in trigger script of Integrity?

java.lang.Runtime.getRuntime().exec('cmd /c start E:\\oval\\CPProject.bat');

is above command is right to execute batch using JAVA API in Integrity server.

I am able to write and read batch file using JAVA API script but above command does not execute the batch file after writing. Kindly help me to execute the batch file in Integrity server.
