Hello Scott,
Yes, I've done that already
To connect to Microsoft SQL Server databases, you need to prepare Microsoft's 
JDBC Driver for SQL 
Server<http://msdn.microsoft.com/en-us/sqlserver/aa937724.aspx> for use with 
the Eclipse environment using the bnd utility available 
here<http://www.topquadrant.com/resources/bnd.zip> or from TopQuadrant's 
Resources<http://www.topquadrant.com/resources/resources_overview.html> page. 
The download is a zip file that includes the biz.aQute.bnd.jar utility. To use 
it, the following command creates a file called sqljdbc4.bar:
java -jar biz.aQute.bnd.jar wrap sqljdbc4.jar
Rename the sqljdbc4.bar file to have a .jar extension (for example, 
sqljdbc4_equinox.jar) and put it in the dropins folder of your TopBraid 
installation
Additionally, I thought I may have screwed the .bar file up, so I found one in 
this thread from June 17th.

To let you know, the Studio did not give the option for the connection type: 
jdbc:jtds:sqlserver:<server......> until I added the modified jar file.
I've tried different driver classes also.

Rocky, please take a look at the Composer Help file at  > Working with Data 
Back Ends > Working with Relational Databases > Importing Relational Databases 
with D2RQ, and follow the link for working with MySQl and SQL server databases.

You will need to install the driver jar for these databases, and the SQL Server 
jar requires an Equinox wrapper.  There are instructions and pointers for 
downloads in the instructions.

Hello,
I'm trying to connect also to a local Instance of MS SQL 2008.
Has anyone been able to do so?

I'm getting the error:

An error has occurred. See error log for more details.
Cannot instantiate SQL Driver net.sourceforge.jtds.jdbc.Driver: please place 
driver file jtds.jar into folder 
C:\tbcme-win32.win32.x86_64-4.3.1.v20131101-1317R\tbcme\dropins\ and restart 
TopBraid
Database connection to jdbc:jtds:sqlserver://6LJV9T1-X7:1433/Movie failed 
(user: tbc): No suitable driver found for 
jdbc:jtds:sqlserver://6LJV9T1-X7:1433/Movie (E54)

I'm attaching the screen shot of my connection object.

I've made my own sqljdbc4.bar file using the utility, and I've also downloaded 
the one found in this thread, but it still doesn't work.
I've also tried using LocalHost in the connection string versus the PC name 
(6LJV9T1-X7)
My Version: : 4.3.1.v20131101-1317R

Any other suggestions?
Thanks,
Rocky

Dear All,

Happy new year everyone, and congratulations on the new release.

I'm using the new Topbraid Standard version 4.1 and I try to connect topbraid 
to a MSSQL Database using the userguide (import -> create connection for RDBMS 
Source (using d2rq)). As instructed I downloaded the latest version of the jtds 
sql drivers, renamed it to jtds.jar and put it into my topbraid/dropins folder. 
I add the remaining connection information (url, username, password) but the 
following error pops up:


An error has occurred. See error log for more details.
Cannot instantiate SQL Driver net.sourceforge.jtds.jdbc.Driver: please place 
driver file jtds.jar into folder [removed folders]\dropins\ and restart 
TopBraid.

Database connection to [removed connection string] failed (user: sa): No 
suitable driver found for [removed connection string] (E54)

The connection string is correct, the database is running, I can access it via 
my own Java DB test script using the very same jtds drivers from the dropins 
folder. I'm working with Java 1.6, tried using older sql drivers, tried 
microsofts sql drivers, tried an old Topbraid version and running topbraid as 
an administrator with no success. Is there anybody experiencing the same 
problems?

Thanks a lot for your support.

kind regards,
Jonas
