What should I do if I’m getting a ClassNotFoundException when trying to connect?

  • From your java control panel, click the Advanced tab. Disable “Use SSL 2.0 compatible clientHello format” and enable "Use TLS 1.0"
  • Some users may experience an error connecting after updating Java that reads "Error. Click for details"
  • Selecting this error brings up a detailed Application Error message that states “ClassNotFoundException” and reads “rss.sdc.SdcApplet.class” in the details. This indicates that Java is configured either not to communicate over TLS1.0 or is configured to use SSL2.0 in addition to TLS1.0.
