My client is a java applet runs from a page. In Safari 9 and before version, it runs OK. But in Safari 10 beta, it fails. I found that safari 10 blocks access to local files from Java applet. So I think it is because the java plugin runs under safe mode. But in Safari -preferences-security-Plug-in Settings. In Safari 10, set to ship with macOS Sierra, Apple plans to disable common plug-ins like Adobe Flash, Java, Silverlight, and QuickTime by default in an effort to focus on HTML5 content and improve.
The Java Embedding Plugin is a utility that allows other webbrowsers than Apple's Safari to use the most recent versions of Javaon Mac OS X. When used together with an updated version of Mozilla'sMRJ Plugin Carbon (included in this distribution), the Java EmbeddingPlugin's functionality is currently available to recent versions ofFirefox, Seamonkey and Camino. Chrome for older mac os catalina. But in principle any web browser coulduse one of the Java Embedding Plugin's two APIs to add support forJava 1.4.2, J2SE 5.0 and (where available) Java SE 6.
The current version (0.9.7.5) of the Java Embedding Plugin and theMRJ Plugin JEP requires Mac OS X 10.4.X or higher. Older versions(0.9.6.5 and earlier) required Mac OS X 10.2.8 or higher.
The Java Embedding Plugin has for the last few years been bundledwith current Mac distributions of all the Mozilla.org browsers --Firefox, Seamonkey and Camino. So if you're using one of thesebrowsers, you don't need to install the Java Embedding Plugin. Butyou may wish to replace the bundled version of the Java EmbeddingPlugin with a more recent version.

Update: Please see Java support in Safari 12 for information about viewing Java content with macOS. The information conveyed in the article below is no longer supported on your Mac.
Some web sites contain Java content that requires a Java Runtime Environment (JRE) to view. If your Mac does not have JRE, you may see a missing plug-in notification instead of the content itself. This usually means your Mac does not have Java enabled, or does not have Java installed. Also see Java support in Safari 12.
Before you can enable Java with Mac, you may need to verify and download it first. If Java is not enabled by default after you download and install it on your Mac, it might need to be manually enabled. To do so, launch the Java Control Panel on your Mac (Apple menu > System Preferences > Java).
Double-click the Java icon in System Preferences. The Java Control Panel will launch in a separate window.
In the Java Control Panel, click the Security tab. Check the Enable Java content in the browser check box, and click OK to save your edit.
So the change takes effect, close all your open web browser windows. In a new browser window, visit the web page with Java content to see if it displays.
Certain web browsers, such as Google Chrome, will block Java content from displaying by default. If you are trying to view a web page with Java content on your Mac using Chrome, try an alternate web browser like Safari or Firefox. If you have no choice but to use Chrome, you can view Java content within the Chrome wrapper using the IE Tab extension. IE Tab uses the Internet Explorer rendering engine so you can view Java content in Chrome. It allows you view ActiveX and Silverlight content too. IE Tab is easy to install, and even easier to use, keeping in mind that it only works on Windows.
