JavaMail API error

[Eduardo Ponce de Leon]

I am trying to send an email from java using the JavaMail API however i am getting an error...

Access restriction: The type FileDataSource is not accessible due to restriction on required library C:\Users\Eduardo\AppData\Local\Genuitec\Common\bin ary\com.sun.java.jdk.win32.x86_1.6.0.013\jre\lib\r t.jar

the error comes from this line in my code...

 //use a JAF FileDataSource as it does MIME type detection
DataSource source = new FileDataSource(filename);
attachmentBodyPart.setDataHandler(new DataHandler(source));

this the code i have been trying to use from the internet
