The Series 4 supports a built-in Websockets interface. Websockets operates through the standard HTTP ports and is supported by all browsers. The JNIOR Websockets interface supports all of the same functionality of the JNIOR Protocol and much more. The JNIOR Protocol is a binary protocol and challenging to implement. Websockets is JSON based and much more straight forward.
If your Series 4 is still presenting you with the applet issue, you need to update. We recommend always that you run the latest JANOS release. The update project for that will replace the applets with the DCP.
You should be running at least JANOS v1.6.2. If you update JANOS manually using a UPD. The DCP is installed by copying the
www.zipfile into the
/flashfolder. You should also make sure that any
index.phpfile is removed from the
www.zipfolder should not be expanded as JANOS serves files directly from the compressed library.
This is what the DCP looks like.
