java.lang.UnsupportedClassVersionError: Bad version number in .class file


Hi I want to use sendGrid Mail Sending feature in Java 1.5 as follows

EmailUtil.sendEmail("reciever", "sender", "subject", "body", "contentType", "apiKey");

Since that exception tells that version does not permit... Is there any alternate to use this feature in Java 1.5

Here is the full Stack of Exception


Solution

  • It is possible to send mail using SendGrid through the common SMTP protocol.

    Information about that option can be found under the following URL: https://sendgrid.com/docs/Integrate/index.html

    To communicate using the SMTP protocol you may use the standard JavaMail API or a wrapper eg. Apache Commons Email. The latest version of commons email is still compatible with Java 1.5.
