1 The source code provided with demos for the JDK is meant

     2 to illustrate the usage of a given feature or technique and has been

     3 deliberately simplified. Additional steps required for a

     4 production-quality application, such as security checks, input

     5 validation, and proper error handling, might not be present in the

     6 sample code.

     8 In some cases, the default security settings may block an execution

     9 of demo applets in a browser. To adjust the security settings, please

    10 refer to the following resource:

    15 protocols to enable access to the required resources.
