Can we connect to LocalDB with either the Microsoft JDBC or JTDS plugins?
Most of the information I've found says "no," especially for Microsoft's plugin. JTDS seemed like it would work, but I have been unable to get that working.
A patch for JTDS was created in Novermber of 2013: http://sourceforge.net/p/jtds/bugs/716/.
Any other suggestions or ideas?
