"PM Error reported by CRC web Service Session Invalid" error

Hello all

I have been configuring version 1.7.12 of the i2b2 web client on a virtual machine against a SQL Server Database. I am able to navigate to the web client and log in successfully with the demo user account credentials. Upon logging in, I am greeted with four error messages saying "An error has occurred in the cell's AJAX library. Press F12 for more Information". Pressing F12 does not provide any more information other than that the server sends no XML response.

wildfly has a much more interesting error message in the form of a warning.

{code:bash}

I may be misinterpreting this error message, but it looks like there is no such method pingDatabase( ) in the com.microsoft.sqlserver.jdbc.SQLServerConnection class. This error message makes the web client unusable.
