Problems upgrading to JDBC 5.1 driver for MS SQL Server

Question

Hi,
I recently upgraded to the Weblogic JDBC 5.1 driver for MS SQL Server and I am
now receiving exceptions in my application when attempting to execute a prepared
statement. I was previously using the Weblogic JDBC 4.x driver for MS SQL Server
and everything was working fine without any problems. For some reason I am receiving
a java.lang.CloneNotSupportedException using the new driver. I am using the setLong(),
setString(), and setObject() methods of the PreparedStatement and then attempting
to execute. The application code has not changed, so it seems that something
has changed in the new driver implementation. Has anyone else had this problem
or know a work around? Here is a snippet of the actual exception:
S2 [09/30/02 10:46]: java.sql.SQLException: java.lang.CloneNotSupportedException
: Error in TdsParameter clone: cannot make duplicate of Stream object

Thanks, Nadeem.

Is it true that the Weblogic jDriver for MS SQL Server is deprecated? That's the
message that I got from BEA Support and here is the link they sent:
http://edocs.bea.com/wls/docs70/mssqlserver4/install_jmsq4.html#415356
It recommends using Microsoft's JDBC driver instead. Any thoughts on this? From
what I understand and what I have read on the newsgroups, the Microsoft JDBC driver
is still quite buggy and has numerous problems.
Thanks, Nadeem.It is deprecated, but still supported, and is more recent in the download than the one in
the 5.1 server. We do recommend MS's driver, or that of www.inetsoftware.de. The
MS driver is fairly stable now, and may certainly have bugs, as does our driver. The MS
driver is good because it is not deprecated, and supports JDBC 2.0 etc.

What version of 5.1? You should be running with the latest service pack.
If that doesn't help, please download the latest 5.1 driver from our
site, and
make sure it's in the weblogic.classpath ahead of all other stuff, by
editting the
startWeblogic script.
