When will Apex ver 21 be available/deployed to Oracle Cloud autonomous databases?

LinnemeyerJul 16 2021

When will the latest version of Apex be deployed to the Oracle Cloud autonomous databases? Under my instance administration it states
System is up-to-date.
Once a new Application Express release becomes available, your instance will be immediately upgraded.
Looking forward to using some of the new features.

JRE may not be enabled in your browser. Check whether it is enabled or not?

You can verify that from 'Tools -> Internet Options -> Advanced -> Java (sun)'

I'm having trouble deciphering that message as well. ..Mostly because you did not copy/paste it.

The JVM being used by the browser is earlier than the version of javac you compiled the applet with.

So update the browser's JVM or use the -target switch of javac.

If you get a message you can't 'decipher', post it. Just saying you can't decipher it only wastes time.

I'm running Java SE 7, which should be the latest version of Java available. Does this mean I need to update my compiler?

Sorry that I keep asking these questions but I want to make sure my applets will run properly in the future.

No, it means that your browser isn't running Java 7, but has an older plugin.

Then maybe use the target flag when compiling so it's compatible with 1.5. Version 1.6 tops. Unless you really need to use all the new features.
