Hi,
When inserting a byte[] with to bytes into the database it doesn't insert the byte[1] if it has 00 value (byte[0] != 0), whereas if the byte[0] has 00 value and byte[1] != 0 the two bytes are inserted.
I still have to test with longer byte[].
Is this the expected behaviour?
Thanks in advance.

Passed test with the below testTextNullvalue.java code. Your error isn't recured. Please let us know more about your issue.
import java.sql.*;

properties.setProperty("fileExtension", "txt");

Hi,
I'm sorry my first question was incomplete. I have observed the commented behaviour when inserting a ResultSet from another oracle jdbc connection using Text suggested code:
String sql="insert into test ?;";
PreparedStatement pstmt = con.prepareStatement(sql);
pstmt.setObject(1,rs);
pstmt.executeUpdate();
pstmt.close();
Regards

The latest package won't rtrim value or return null value for char type and binary type now.
