no sqljdbc_auth in java.library.path

Question

I have a Java EE Web Application which connects to a SQL Server 2008 instance. I don\'t have any problem connecting and retrieving to all my tables, except for one of them.

Answer 1

I've just encountered the same problem but within my own application. I didn't like the solution with copying the dll since it's not very convenient so I did some research and came up with the following programmatic solution.

Basically, before doing any connections to SQL server, you have to add the sqljdbc_auth.dll to path.. which is easy to say:

PathHelper.appendToPath("C:\\sqljdbc_6.2\\enu\\auth\\x64");

once you know how to do it:

import java.lang.reflect.Field;

public class PathHelper {
    public static void appendToPath(String dir){

        String path = System.getProperty("java.library.path");
        path = dir + ";" + path;
        System.setProperty("java.library.path", path);

        try {

            final Field sysPathsField = ClassLoader.class.getDeclaredField("sys_paths");
            sysPathsField.setAccessible(true);
            sysPathsField.set(null, null);

        }
        catch (Exception ex){
            throw new RuntimeException(ex);
        }

    }

}

Now integration authentication works like a charm :).
