Problem connecting to SQL Server from JDeveloper 10g using jdbc third party

Question

I am using Oracle 10g Jdeveloper and I tried to setup a database
connection to SQL Server using various Drivers for JDBC as Merlin, jtds, inet.tds, etc.
(I had no problem to set up a connection to an Oracle Database using the
Oracle JDBC driver).
When I am testing the connection throughout the wizard, I do receive
this error message: "Unable to find driver:
com.microsoft.jdbc.sqlserver.SQLServerDriver".
I m not understanding from last 3 days where to place the corresponding JAR files so thaI may not get the Error.
When I hit n trialed at various directories of the JDeveloper as </rootDir/jdbc/lib>
</rootDir/lib>
</root/jdev/my Work/Application1/Project1/public_html>
</root/jdev/my Work/Application1/Project1/public_html/web-inf/>
when I tested the connection I do received:
"Unable to find driver:
xxx.xxx.xxx.xxxxxxx Unable to find driver:
Obviously it can't locate the Micrososft JDBC driver but I can't
figure out why.
I tried all kind of things without any success. Is somebody can help
me and took me beyond this.
I m trying to build DataSource connection from JavaBeans.
Please make me out of this cave. I m not finding any of the way to do this.
The last code I tried is
try {
Class.forName("com.inet.pool.PoolDriver");
com.inet.tds.TdsDataSource tds = new com.inet.tds.TdsDataSource();
tds.setServerName( "local" );
tds.setDatabaseName( "bluff" );
tds.setUser( dbUserName );
tds.setPassword( dbPassword );
DataSource ds = tds;
Connection con = ds.getConnection(dbUserName,dbPassword);
Statement stmt;
ResultSet rs = null;
Thanks,

you are confusing me at least as your error is discussing the microsoft driver yet you are configuring the inet datasource.
I do not use JDeveloper, but you need to make sure that whatever is servicing your web app/JavaBean has access to the driver. Not sure why you are not doing a JNDI look up of the resoure, but because you are not you can stick the driver jar in the lib directory within the WAR bundle. I would suggest that you add the driver to the lib/ext or the lib directory which is loaded at boot time for your web container and then use JNDI to look up your DataSource to reduce your coding maintenance headaches.
