You should create a new directory under the EnterpriseWS directory to hold your custom code, and then add this code to the EnterpriseWS project. Your code should never be intermingled with the regular EnterpriseWS code so it's can't be overwritten. In other words, always keep your custom code in a separate directory under the EnterpriseWS project.

If you want to customize existing code, never modify the existing code "in-place". Code that is edited "in-place" is subject to accidental deletion during updates. If you want to modify existing code, first create a separate directory under the EnterprieWS directory, and then make a copy of the code you want to modify in the custom code directory that you just created, and then modify the code in this directory.
