CORBA - An Introduction to Network Programming with Java - page 159

(ix) Wait for client calls .

Unlike our previous server programs, this is not achieved via an explicitly
'infi nite' loop. A call is made to method wait of (Java class) Object . This call
is isolated within a code block that is declared synchronized , as shown
below.

java.lang.Object syncObj = new java.lang.Object();
synchronized(syncObj)
{
syncObj.wait();
}
All of the above code will be contained in the server's main method. Since vari-
ous CORBA system exceptions may be generated, all the executable code will be
held within a try block.
Now for the full program…
