I am in the middle of a Oracle to Postgres migration and have some difficulty with properly configuring the XA driver. I need to set the stringtype=unspecified property, but that seems to be ignored with the XA driver. It seems to work fine with the non-xa driver, but since I am in the middle of this conversion I need to be able to work with the Oracle and Postgres datasources within the same transaction.
I am using the postgresql-9.2-1002.jdbc4 jar with Weblogic 10.3.
