I am facing the following problem while inserting a record with BLOB. See the following Java Program.
public boolean METHOD_NAME()
{
boolean sucessFlag = false;
File fileObject = new File("FILE_NAME.XLS");
FileInputStream finObject = new FileInputStream(fileObject);
Connection con = DbUtil.getDBConnention();
StringBuffer sb = new StringBuffer();
sb.append("INSERT INTO TABLE_NAME(BLOB_COLUMN) VALUES(?)");
PreparedStement pstmt = con.prepareStement(sb.toString());
pstmt.setBinaryStream(1, finObject, fileObject.length());
boolean sucessFlag = pstmt.execute();
}
The above code is executing fine without having Exception. But, I am getting successFlag as false after executing the SQL. Can anyone help me.
I am using DB2 Universal JDBC 2 Driver.
Thanks

If u installed WL 6.1 Service Pack then weblogic_sp.jar file comes along with this Pack. Or If u have WEBGAIN Studio 4.5.2 then the file is there in the path specified in the SETENV.CMD file. But in the case of WL7.0, it has only weblogic.jar file in \lib directory.
Guys,
Tell me, Excellent book for J2EE and EJB Transactions.
Thanks,
