Basic Tab

The Basic tab controls the basic operations of Java Plug-in and includes the following options:

• Enable Java Plug-in -- Runs applets, JavaBeans, and other components using Java Plug-in. The default setting is selected.

• Show Java Console -- Displays the Java Console while running applets or JavaBeans components. The console displays messages printed by the System.out and System.err objects, and is useful for debugging problems. The default setting is selected.

• Cache JARs in Memory -- Caches (reuses) previously-loaded applets or component classes, allowing for more efficient memory use. Uncheck this option when debugging an applet or component, or if you want to ensure that the latest applets or component classes are downloaded. The default setting is selected.

• Network Access -- With Java Plug-in, applets run under the standard JDK applet security manager, which prevents untrusted applets from performing potentially dangerous operations such as reading local files. Refer to the Java Security FAQ and Using Signed Applets with Java Plug-in for more details.

  You can assign one of the following network access allowances to your running applets and components:

  • None -- Grants no access to the network.

  • Applet Host -- Restricts an applet's network access so that the applet cannot make any network calls (default setting).

  • Unrestricted -- Grants an applet unrestricted access to the network, so the applet can connect to any host server.

  Caution -

  It is a security hazard to grant unrestricted network access to applets.

  ---

• Java Runtime Parameters -- Enables you to enter custom options that override the Java Plug-in default startup parameters. The syntax is the same as the parameters to the java command-line invocation. For more information, type man java at the command line to view the Java man page.

  Note -

  Refer to the JDK 1.2 documentation for information on specifying the command-line parameters when invoking the java command.
