// This example client program utilizes an SSLContext object, which it initializes

|
|
//
|
|
// The example uses the native iSeries JSSE provider, regardless of the
|
|
// properties specified by the java.security file.
|
|
//
|
|
// Command syntax:
|
|
// java -Djava.version=1.4 SslClient
|
|
//
|
|
// Note that "-Djava.version=1.4" is unnecessary when you have configured
|
|
// J2SDK version 1. to be used by default.
