How to get the filename from J2SE File adapter

In our project scenario , we are using J2EE and J2SE engine both .J2EE for mapping and J2SE for Deliveying the message .

In one senario, routing will be based on the filename .

J2SE Sender File adapter --- XI Adapter --- XI pipe line

So the File reaching to XI pipelane via J2SE File adapter--> XI adapter.

When we are using the dynamic configurator in the XI to get the filename

we are not able to get the file name becasue it is coming to XI via

XI adapter.

How to get the filename ????Hope I am clear about the problem.
