The ToUpper.java Java code fragment in the following listing illustrates how Jolt works with a service with a buffer type of STRING. The example shows a Jolt client using a STRING buffer to pass data to a server. The Oracle Tuxedo server would take the buffer, convert the string to all uppercase letters, and pass the string back to the client. The following example assumes that a session object was already instantiated.
