title: mySQL Driver class not found in JDeveloper 11g
body: <p>In testing an existing Oracle SOA Composite using Oracle JDeveloper 11g Release 1 (11.1.1.7.0).  When I try to test one of the connections to the mySQL database I see this error: "Test failed: Driver class not found. Verify the Driver location".  </p>
  
  <p>I have added the mySQL Library in JDeveloper and pointed it to the JAR file as pointed out here:<a href="https://stackoverflow.com/questions/15314453/jdeveloper-mysql-error-driver-not-found">JDeveloper MySQL error Driver not found</a></p>
  
  <p>I also ran through the steps to outline adding the JAR here:<a href="http://jdev11g.blogspot.com/2009/04/oracle-jdeveloper-11g-with-mysql.html" rel="nofollow noreferrer">http://jdev11g.blogspot.com/2009/04/oracle-jdeveloper-11g-with-mysql.html</a></p>
  
  <p>I have tried mapping the library to the JAR as well as moving the JAR under JDeveloper in C:\Oracle\Middleware\jdeveloper\jdev\lib and mapping it there.</p>
  
  <p>When I go to the Database Navigator and try to connect I get an Error encountered alert stating "An error was encountered performing the requested operation: Driver class not found. Verify the Driver location Vendor code 0."</p>
  
  <p>Thanks,</p>
