<pre>//////////////////////////////////////////////////////////////////////////////////
|
|
//
|
|
// The following server program utilizes an SSLContext object that it
|
|
// initializes with a previously created keystore file.
|
|
//
|
|
// The keystore file has the following name and keystore password:
|
|
// File name: /home/keystore.file
|
|
// Password: password
|
|
//
|
|
// The example program needs the keystore file in order to create an
|
|
// IbmISeriesKeyStore object. The KeyStore object must specify MY_SERVER_APP as
|
|
// the application identifier.
|
|
//
|
|
// To create the keystore file, you can use the following Qshell command:
|
|
//
|
|
// java com.ibm.as400.SSLConfiguration -create -keystore /home/keystore.file
|
|
// -storepass password -appid MY_SERVER_APP
|
|
//
|
|
// Command syntax:
|
|
// java -Djava.version=1.4 JavaSslServer
|
|
//
|
|
// Note that "-Djava.version=1.4" is unnecessary when you have configured
|
|
// J2SDK version 1. to be used by default.
