Editing Java applet (section)

== Embedding into a web page ==
The applet would be displayed on the web page by making use of the deprecated <code>[[Img (HTML element)|applet]]</code> HTML element,<ref>{{Cite web|url=http://www.w3.org/TR/html401/struct/objects.html#edef-APPLET|title=Objects, Images, and Applets in HTML documents|website=W3.org|access-date=22 March 2022}}</ref> or the recommended <code>object</code> element.<ref>{{Cite web|url=http://www.w3.org/TR/html401/struct/objects.html#edef-OBJECT|title=Objects, Images, and Applets in HTML documents|website=W3.org|access-date=22 March 2022}}</ref> The <code>embed</code> element can be used<ref name="java">{{cite web|url=http://www.java.com/en/download/manual.jsp |title=Java Downloads for All Operating Systems |publisher=Java.com |date=14 August 2012 |access-date=2013-06-14}}</ref> with Mozilla family browsers (<code>embed</code> was deprecated in HTML 4 but is included in HTML 5). This specifies the applet's source and location. Both <code>object</code> and <code>embed</code> tags can also download and install Java virtual machine (if required) or at least lead to the plugin page. <code>applet</code> and <code>object</code> tags also support loading of the serialized applets that start in some particular (rather than initial) state. Tags also specify the message that shows up in place of the applet if the browser cannot run it due to any reason.

However, despite <code>object</code> being officially a recommended tag in 2010, the support of the <code>object</code> tag was not yet consistent among browsers and Sun kept recommending the older <code>applet</code> tag for deploying in multibrowser environments,<ref name="ja">{{Cite web |url=http://download.java.net/jdk7/docs/technotes/guides/plugin/developer_guide/using_tags.html#object |title=Sun's position on applet and object tags |access-date=14 January 2010 |archive-url=https://web.archive.org/web/20100609015456/http://download.java.net/jdk7/docs/technotes/guides/plugin/developer_guide/using_tags.html#object |archive-date=9 June 2010 |url-status=dead }}</ref> as it remained the only tag consistently supported by the most popular browsers. To support multiple browsers, using the <code>object</code> tag to embed an applet would require JavaScript (that recognizes the browser and adjusts the tag), usage of additional browser-specific tags or delivering adapted output from the server side.

The Java browser plug-in relied on [[NPAPI]], which nearly all web browser vendors have removed support for, or do not implement, due to its age and security issues. In January 2016, Oracle announced that Java runtime environments based on JDK 9 will discontinue the browser plug-in.<ref name="ars-nopluginjdk9">{{cite web|title=Oracle deprecates the Java browser plugin, prepares for its demise|url=https://arstechnica.com/information-technology/2016/01/oracle-deprecates-the-java-browser-plugin-prepares-for-its-demise/|website=Ars Technica|date=28 January 2016 |access-date=15 April 2016}}</ref>
