[NIFI] Cannot create PoolableConnectionFactory (The connection attempt failed.)

[#1]

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
  
  

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
  

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

org.apache.nifi.dbcp.DBCPConnectionPool DBCPConnectionPool[id=67dc5ad3-0189-1000-09ac-b19f6c25590c] Failed to establish Database Connection
