title: Adding JPA-Connection in Eclipse
body: <p>After 5 hours of trying and not finding any solution to my problem, maybe you guys can help me. I´ve been trying to add a database connection to my eclipse JPA-project, but the window in Eclipse won´t let me pass on:</p>

  <p>I am using Eclipse Link 2.5.2 and JPA 2.1 with the newest Eclipse Neon release, my Database is an MSSQL-Server 2012. I have implemented a JDBC connection, which  works just fine (to make sure the Server-Ports are open and the connection-URL etc. is correct).</p>
  
  <p>If i want to add a new connection with <strong>new</strong>-><strong>other</strong>-><strong>Connection Profiles</strong>-><strong>Connection Profile</strong> in my JPA-Project. Eclipse lets me choose the <strong>Connection Profile Type</strong> where I select <strong>SQL Server</strong>, then I define a new Driver with <strong>New Driver Definition</strong>, where I take <strong>Microsoft SQL Server 2012 JDBC Driver</strong>, add the sqljdbc4.jar (which is located in my lib folder and added to the build path). Lastly I add the connection URL and the other preferences. After I click <strong>OK</strong>, I cannot move on from there because the buttons are disabled. Did anyone experienced the same problem or knows a solution for this? Thanks in advance!</p>
