The driver could not establish a secure connection

Question

I used this code to create a connection to SQL Server.

String connectionUrl = "jdbc:sqlserver://IP:1433;" +
        "databaseName=db;user=db;password=pwd";
    Connection con = null;
  try {
     // Establish the connection.
     Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
     con = DriverManager.getConnection(connectionUrl);
        return "true";
  }

  // Handle any errors that may have occurred.
  catch (Exception e) {
     e.printStackTrace();
  }

but i got this error:

com.microsoft.sqlserver.jdbc.SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "Socket closed". ClientConnectionId:5975fad5-8f8d-496a-a2bb-bff3a8d1a755

Can anybody help me? Thanks in advance

Answer 1

Check out this Microsoft JDBC Blog post:

• The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption.

for resolve SSL problems with SQLServer (specially for android clients:JDBC driver can not be used effectively in the Android OS on unfortunately) try to using jDTS:

jTDS is an open source 100% pure Java (type 4) JDBC 3.0 driver for Microsoft SQL Server (6.5, 7, 2000, 2005, 2008 and 2012)

Answer 2

Is it

databaseName=MyDB

or

database=MyDB

?

Try the latter.

Are you on a Windows Machine? http://www.microsoft.com/en-us/download/details.aspx?id=24009

Download that and try to talk to your server outside of your code. The port query tool will show you if its a firewall (or similar) issue, outside of the code.
