Answer 1

You have enabled integratedSecurity . This means that the sqljdbc_auth.dll needs to be on the library path of the jvm.

Most likely you do not have this library on your path, it is the wrong version or the wrong variant (x86 <> x64 <> IA64).

Answer 2

An old question but I had this issue today. I don't know the first thing about Java but for me the fix was to copy Microsoft's JDBC driver to Java's ext folder.

sqljdbc41.jar needs to be copied to C:\\[path to java installation]\\Java\\jre7\\lib\\ext\\

Make sure you pick the right version (x86 or x64).

Also for Integrated Security I needed to make a reference to auth when starting my application.

-Djava.library.path=C:\[Path to Microsoft JDBC Driver 4.1 for SQLServer]\sqljdbc_4.1\enu\auth\x86

Answer 3

I had the same exception when starting SpringBatch with an JdbcBatchItemWriter writing to MS SQL Server 2008.

Sqljdbc_auth.dll was on the library path. It turned out that I was running my SpringBatch application in Eclipse with JRE 1.6. I solved this by running it with JRE 1.7 (Eclipse JRE-Tab in Run-Configurations).
