title: SQL Developer - No readers registered for SQL type error
body: <p>I am using Oracle 11g. I had exported data using the installed version of SQL Developer to a sql file called "export.sql".  Now, I have downloaded the new version which is 3.1.07 and when I try to import data by clicking on the tree view and choosing Tables | Import Data and navigating to "export.sql", I get the following error:</p>
  
  <blockquote>
    <p><strong>no readers are registered for the sql type</strong></p>
  </blockquote>
  
  <p>When I first started the application it asked for the path to java.exe and I have shown that path and application started. I have the started the application from the path where it was downloaded (<strong>C:\users\kaushik\Downloads\sqldeveloper</strong>)</p>
