Hi,

I am using the following config file to upload a simple table to Elasticsearch:  
input {  
jdbc {  
jdbc\_driver\_library =\> "C:/Users/michaeos/Desktop/ELK/logstash-7.6.2/sqljdbc\_4.2/enu/jre8/sqljdbc42.jar"  
jdbc\_connection\_string =\> "jdbc:sqlserver://iibdspdev.inr.rd.hpicorp.net;databaseName=impact21;integratedSecurity=true;”  
jdbc\_driver\_class =\> "com.microsoft.sqlserver.jdbc.SQLServerDriver"  
jdbc\_user =\> "xxx"

```
statement => "SELECT * FROM Users"

```

}  
}

output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "cs\_users"  
}  
}

when I run it I get an exception:

Welcome! 😃  
Please remember to format your code/logs/config using the `</>` button, or markdown style back ticks. It helps to make things easy to read which helps us help you.

Are you able to post more of the log/exception output?
