I'm getting this 2 errors repeatedly when I'm trying to connect eclipse with sql server through jdbc. Could anyone help me with this or explain why am I getting this?
1. The TCP/IP connection to the host localhost, port 1433 has failed. 2. The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption.
Thank you.
String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; Class.forName(driver).newInstance(); String connString ="jdbc:sqlserver://localhost:1433/databaseName=Engg_Street;instance=SQLSERVER;encrypt=true; trustServerCertificate=true"; String username = "Vijayalakshmi"; String password = ""; conn = DriverManager.getConnection(connString,username,password);

You need to Go to Start > Microsoft SQL Server > Configuration Tools > SQL Server Configuration Manager
When it opens Go to
SQL Server Configuration Manager > SQL Server Network Configuration > Protocols for SQLExpress
Where you'll find the Protocol TCP/IP, if disabled then Enable it Click on TCP/IP, You'll find its properties.
In this properties Remove All the TCP Dynamic Ports and Add value of 1433 to all TCP Port and restart your SQL Server Services > SQL Server
And Its Done...

Start all the above services. and set to start up type to Automatic.
SQL Active Directory Helper Service is not required to keep running.
