Connector Appliance 6.1 / 6.2 quick notes for upload of JTDS driver for connection to Microsoft SQLServer database. Quick, dirty and not complete. But some notes nonetheless. Hope they are of some use.

  • Thank for the helpful post.  I ended up using jtds v1.2.7 for a MSSQL Flexconnector to a MSSQL 2008 R2 database that required windows authentication and TLS encryption.  A couple things to add:

    - For databases requiring encryption, you must add the public certificate from the database server to the NSSDB (via the container certificates wizard), then add ;ssl=request or ;ssl=require to the connection string

    - The container would not start up with versions beyond 1.2.7, I'm not sure if there is a way to bypass this

    - The BEAST fix in Java causes problems connecting with the JTDS driver on databases requiring encryption (see: jTDS not connecting with SQL Server 2008 R2 SP2... | Oracle Community), this check can be turned off by adding the following to the agent.wrapper.conf file:

    wrapper.java.additional.7=-Djsse.enableCBCProtection=false

    From my understanding, BEAST is a server side fix.  So assuming that the DBAs have disabled TLS v1.0, the connection should use a non-vulnerable protocol TLS 1.1/1.2.  I'm not positive on this and haven't confirmed so you may want to do your own research.

  • Thanks for documenting this for posterity! Hopefully it does not get lost as did my (much quicker) notes in some forum post some years ago...

  • Oh, another typo on page 5:

    The class is "net.sourceforge.jtds.jdbc.Driver" not "net.sourceforce.jtds.jdbc.Driver"

  • Typo on page 7:

    The jdbc url connection string must start with "jdbc", not "Jdbc".
