Unable to construct a Datum from the specified input的解决方法

Q:
I am working with Oracle database 8.1.7 and I have written a JAVA code to update the table which contains one BLOB field .

I am using updateBinaryStream method of resultset to update the BLOB field but it is failing after giving following exception

java.sql.SQLException: Internal Error: Unable to construct a Datum from the specified input

Can anyone help me in this regard ?


A:
That's because you are using FileInputStream. FileInputStream doesn't implement all methods of java.io.InputStream. Use java.io.File instead.
