Initial Comment:
In my oracle10g db, there are some BLOB type data, about 30MB, when i export it with thesecode.
 FlatXmlDataSet.write
                (partialDataSet, new FileOutputStream
                  (targetDirectory + "/" + tableName + ".xml"));

Message:
Is this really a dbunit bug? I am not sure. Could you please try to
increase the max-heapsize (I suggest 512m)?

java -Xms<initial heap size> -Xmx<maximum heap size>

Defaults are:

java -Xms32m -Xmx128m

Regards,
mat
