Transaction Timeout (BPEL v10.1.2.0.0, WebLogic 8.1 sp4)

Question

We are attempting to process a transform on a medium sized xml doc (~4.5 MB). For the test case we are simply reading the the doc using the FileAdapter, performing a transformation, and then writing the result to a file using the FileAdapter once again. The flow works fine for smallish files (under ~4MB), however, when dropping a file greater than that size the flow fails once finished while writing entries to the BPEL audit log with a TransactionTimedOutException (see exception below).
I understand what is happening and why (it certainly takes longer than 2 mins to process the file). I have also done quite a bit of digging around for references to this issue and found several posts regarding bumping the transaction timeout value when running the OC4J container. My problem is that we are not running the OC4J container. I know how to manage the default transaction timeout value for WebLogic but it appears that the BPEL application doesn't seem to be honoring the default transaction timeout on the WL Server. I have come to this conclusion for two reasons: first, the default transaction timeout on the WL Server (before modification) is 30 seconds, not the 120 seconds that this transaction is timing out on. second, changing the transaction timeout value on the WebLogic server has no impact on this issue what so ever. I can set the transaction timeout to any value I like, the process ALWAYS times out after 120 seconds.
Is there another setting on the BPEL server that I may have missed that is overriding the default timeout, i.e. is it possible that when the BPEL server process is starting the transaction it is setting the timeout on the TransactionManager in code prior to starting the transaction?
Any pointers are greatly appreciated.
