Searching Order within a Package
When Integration Server searches within a package for a class, it uses this order:
1. packageName\resources
2. packageName\lib
3. packageName\code\jars
4. packageName\code\classes
Note:
When a package requires another package, Integration Server will first look for a referenced class in the above order within the package that refers to the class. Then Integration Server will look in the above order in the required packages.
