Hi,

I'm trying to configure a JRDC services to connect to a Sql Server 2017 database.
I've downloaded the jdbc driver from Microsoft and included it in the project.
I have a local database running and I can access the database using the Server Manager using the credentials specified in the config file.

When I try to access the /test using a browser I get a no suitable driver error.

Any ideas what I could be doing wrong?

This is the content of my config file:

#Lines starting with '#' are comments.
#Backslash character at the end of line means that the command continues in the next line.
#DATABASE CONFIGURATION
DriverClass=com.microsoft.sqlserver.jdbc.SQLServerDriver
#DriverClass=com.mysql.jdbc.Driver
JdbcUrl="jdbc:sqlserver://localhost:1433;databaseName=AdmConcept;user=sa;password=Zandstraat11;"
#JdbcUrl=jdbc:mysql://localhost/test?characterEncoding=utf8
User=sa
Password=Zandstraat11
#Java server port
ServerPort=17178
#example of MS SQL Server configuration:
#DriverClass=net.sourceforge.jtds.jdbc.Driver
#JdbcUrl=jdbc:jtds:sqlserver://<server address>/<database>
#example of postegres configuration:
#JdbcUrl=jdbc:postgresql://localhost/test
#DriverClass=org.postgresql.Driver
#SQL COMMANDS
#sql.create_table=CREATE TABLE IF NOT EXISTS animals (\
# id INTEGER PRIMARY KEY AUTO_INCREMENT,\
# name CHAR(30) NOT NULL,\
# image BLOB)
#sql.insert_animal=INSERT INTO animals VALUES (null, ?,?)
#sql.select_animal=SELECT name, image, id FROM animals
sql.create_table=CREATE TABLE article (col1 numeric(10,4) ,col2 text);
sql.select=select * from article
sql.insert=INSERT INTO article VALUES(?, ?)


Thx,
Bernaert Dominique

Hi Erel,

yes, this is the sourcecode.
All I changed is that line from the original source.

'Non-UI application (console / server application)
#Region Project Attributes
#CommandLineArgs:
#MergeLibraries: True
#End Region
'change based on the jdbc jar file
#AdditionalJar: mssql-jdbc-6.4.0.jre8
Sub Process_Globals
Public srvr As Server
Public rdcConnector1 As RDCConnector
Public const VERSION As Float = 2.21
Type DBCommand (Name As String, Parameters() As Object)
Type DBResult (Tag As Object, Columns As Map, Rows As List)
End Sub
Sub AppStart (Args() As String)
srvr.Initialize("")
rdcConnector1.Initialize
srvr.Port = rdcConnector1.serverPort
srvr.AddHandler("/test", "TestHandler", False)
srvr.AddHandler("/rdc", "RDCHandler", False)
srvr.Start
Log($"jRDC is running (version = $1.2{VERSION})"$)
StartMessageLoop
End Sub

Remove the semicolon at the end of the string.

#JdbcUrl=jdbc:mysql://localhost/test?characterEncoding=utf8
User=sa

You don't need the user name and password in the JdbcUrl if you are setting the user name and password in the config file.
Also have you configured your Server Authentication for Windows Authentication and SQL Server authentication?

Changed it, does not help.
Yes, I have this configured as you can see in the screenshots.
In Sql server management studio I'm actually connected using these credentials (sa - Zandstraat11)
