Java is blocked by Security Settings in Opera

I opened a webpage required Java, and failed


Your security settings have blocked an application from running with an insecure or expired jre.


But my java version is 1.7.0_21


How can I do? Thanks

Dont enable java runtime environment in browers, it is a HUGE SECURITY RISK!
Even with the latest version of java, you are still exposing yourself to malicious attacks.

Whatever website you want to visit which requires you to enable JAVA, consider if it is worth the risk.

MathWorld requires Java, and it's a famous math encyclopedia website

Go into Opera and check Tools > Advanced > Plugins.
See if java is enabled and note the version of the plugin.

You may have to try different browser.

Thank you very much! I have found a mistake in settings, and fixed it, and it works.

I use Chrome too, but Chrome blocks Java even if I have installed the lastest Java, it is said that Chrome is not compatible with Java well.
