Hi @priya,

What exactly do you mean by opening local files in java/groovy when being run in a browser is forbidden? Did you try reading locally hosted files using groovy processor? Are you facing any error? You might also want to look at processing using jython processor.

Yes, i tried reading locally hosted files using groovy processor and i am getting error as  (java.security.AccessControlException:access denied(“java.io.FilePermission”) .

My requirement is to read and join the files in groovy processor.

@Priya : you need to add permissions to the files. Refer to the below documentation :
