Hi Erel and Expert guys out there,

Getting error fetching connection when connecting to mssql server using b4j web server app. I can able to connect using mysql but for mssql using the jtds-1.3.1 library I cannot figured it out.


B4j:
#AdditionalJar: jtds-1.3.1

config.properties
#example of MS SQL Server configuration:
DriverClass=net.sourceforge.jtds.jdbc.Driver
JdbcUrl=jdbc:jtds:sqlserver://192.168.0.13/test
ServerPort=17178

tried also adding user and password below but still getting same error.
User=sa
Password=password


Error in browser:
RemoteServer is running (03/13/2019 11:29:45)
Error fetching connection.


Waiting for debugger to connect...

Still getting same error Erel. I'm using sql express, so in the sql server management studio I'm connecting using <computername>\SQLexpress.

Should this be the configuration?

#example of MS SQL Server configuration:
DriverClass=net.sourceforge.jtds.jdbc.Driver
JdbcUrl=jdbc:jtds:sqlserver://127.0.0.1/test
User=sa
Password=samplepassword
ServerPort=17178

Got this now Erel..

1. Need to Start the SQL Server Browser
2. Correct MSSQL configuration in the config properties:

DriverClass=net.sourceforge.jtds.jdbc.Driver
JdbcUrl=jdbc:jtds:sqlserver://127.0.0.1/<database_name>;instance=SQLEXPRESS
User=<your_user_name>
Password=<user_password>
ServerPort=17178


Thanks Erel for the help
