Hi Team,

I am a newbie for nifi. I am trying to connect mssql 2008 by using DBCPConnectionPool.

The following are my setting:

 

  • Docker Desktop:v4.19.0
  • Nifi:v1.22.0
  • JDBC Driver:jtds-1.3.1.jar
  • JDBC Driver location:/opt/nifi/nifi-current/lib/jtds-1.3.1.jar

    nifi jtds driver location.png

 

DBCPConnectionPool Configure Controller Service:

 

  • Database Connection URL:jdbc:jtds:sqlserver://xxx.xxx.xx.xx:1433/xxxxx
  • Database Driver Class Name:net.sourceforge.jtds.jdbc.Driver
  • Database Driver Location(s):/opt/nifi/nifi-current/lib/jtds-1.3.1.jar
  • Database User:xxx
  • Password:xxx
  • Validation query:Select 1 as test

nifi controller service connet failed.png

 

And I try to Verify Controller Service Configuration get the message bellow:
