The <code>java</code>, <code>netscape</code>, and <code>sun</code> properties represent the packages <code>java.*</code>, <code>netscape.*</code>, and <code>sun.*</code> respectively. Use standard Java dot notation to access the classes, methods, and fields in these packages. For example, you can access a constructor of the <code>Frame</code> class as follows: +</p> +<pre class="eval">var theFrame = new Packages.java.awt.Frame(); +</pre> +<p>For convenience, JavaScript provides the top-level <code>netscape</code>, <code>sun</code>, and <code>java</code> objects that are synonyms for the Packages properties with the same names. Consequently, you can access Java classes in these packages without the Packages keyword, as follows: +</p> +<pre class="eval">var theFrame = new java.awt.Frame(); +</pre> +<p>The <code>className</code> property represents the fully qualified path name of any other Java class that is available to JavaScript.
