Global variables in Java Mapping


I have a java mapping function in PI 7.1 that transforms an XML document to a legacy data structure which eventually is written to a flat file. The file name is required to be sequenced for each mapping run. For example,

1. The first message generates FILE_001.dat

2. the second message generates FILE_002.dat

3. the counter resets to 001 after 999.

Due to the complexity of the mapping, I have to use a Java class to map this.

What is the best way possible to achieve this? I wonder this can be achieved using the GlobalContainer, but I am not sure whether I can access this class from within AbstractTransformation class.

Any pointers?

Thanks and best regards,
