TP3 - Generic JDBC Seems Not Working - Connection Worked in TP2 but Not TP3

Question

I had a connection working in TP2 to a PosgreSQL database. I have done in TP3 exactly what I did in TP2 to set up the connection but the connection test fails listing the name of the driver.
I put the JAR in jdev\lib, I added a class/library to the default project properties with the classpath listing the location of the JAR including the filename, then I created a new connection with the same driver name, user/password, and JDBC URL I used in TP2. None of this worked though. I even tried restarting JDeveloper.
Any ideas on what I could be doing wrong or if something new needs to be done in TP3?
On a side note, although I got the connection working to the PostgreSQL db working in TP2, JDeveloper was never able to find its tables like when creating an entity from a table for example. I know this is not an issue with the driver JAR because this works flawlessly in Netbeans 6.
Thanks in advance for any help.

Hi CM and Chris,
I have the exact same problem when I tried to create a connection to SQL Server 2005 using Generic JDBC. It worked well for TP2 but does not work for TP3. Further more if you create it anyway, you will get following message in testing:
An error was encountered performing the requested operation:
com.microsoft.sqlserver.jdbc.SQLServerDriver
Vendor code 0.
I tried to export the working connection from JDeveloper 10.1.2. and import it to TP3. I could not solved the problem.
Then I export the SQL server connection from TP3. The connection is expressed as
<Reference credentialStoreKey="yuwyuw" className="oracle.jdeveloper.db.adapter.DatabaseProvider" name="yuwyuw">
<Factory className="oracle.jdeveloper.db.adapter.DatabaseProviderFactory"/>
<RefAddresses>
<StringRefAddr addrType="subtype">
<Contents>thirdParty</Contents>
</StringRefAddr>
<StringRefAddr addrType="user">
<Contents>yuw</Contents>
</StringRefAddr>
<SecureRefAddr addrType="password"/>
<StringRefAddr addrType="driver">
<Contents>com.microsoft.sqlserver.jdbc.SQLServerDriver</Contents>
</StringRefAddr>
<StringRefAddr addrType="DeployPassword">
<Contents>false</Contents>
</StringRefAddr>
<StringRefAddr addrType="customUrl">
<Contents>jdbc:sqlserver://host:1433</Contents>
</StringRefAddr>
</RefAddresses>
</Reference>
It seems DatabaseProviderFactory could not create connection other than Oracle. BBut JDev10.1.2 does not use Factory class. I tested Driver and URL by a small program that created a connection using connection string. No problem at all.
Now I have 2 questions:
1)How can we access the source code to see what happens when we submit connection creation request?
2)You mentioned that we can swap JVM version. But this can only be done on project level. Can we do it on IDE level, because IDE connection is not associated with any project.
Thanks,
