title: birt:add datasource but the eclipse not responding
body: <p>I'm trying to create a new datasource using SqlServer JDBC driver(sqljdbc4.jar) with the following credentials</p>
  
  <pre><code>Driver class : com.microsoft.sqlserver.jdbc.SQLServerDriver (v3.0)
  Database URL : jdbc:sqlserver://xx.xx.xx.xx:1433;DatabaseName=xxx;
  </code></pre>
  
  <p>But when I'm clicking "Test Connection..." button to test the connection, the entire BIRT eclipse is not responding for a long time. Also the same credentials are successfully creating datasource in Navicat tools.</p>
  
  <p>Let me know if you need any more information.Please help me,thanks~!</p>
