- This directory contains an example that illustrates an applet that
- exports a remote object in order to receive stock updates from a stock
- server. The applet displays the stock data dynamically as
- notifications are received from the server. The interfaces and classes
- for this example are:
-
- StockWatch remote interface for stock server
-
- StockNotify remote interface for stock observer
-
- Stock serializable object containing stock data
-
- StockServer (implements StockWatch)
- sends notifications of stock updates to remote
- objects that have registered to receive updates
-
- StockApplet (implements StockNotify)
- applet that exports a remote object (itself);
- registers with StockServer for stock updates;
- displays stock notifications as they are received.
-

- On Windows systems, you can execute "run.bat" in this directory, which
- will explain each step as it builds and runs the example. Upon
- completion, you will need to explicitly destroy the window created for
- the server process.
-
- On the Solaris(TM) operating system, after downloading the Java(TM) 2
- SDK, Standard Edition, v1.2.2, execute the "run" script in this
- examples/stock directory, and the script will print out what it is
- doing while it runs the example. It assumes that you have installed
- the Java(TM) 2 SDK, Standard Edition, v1.2.2 and set your PATH,
- CLASSPATH and LD_LIBRARY_PATH according to the SDK installation
- instructions. The stock server creates its own RMI registry, so the
- "rmiregistry" command does not need to be run. Here are the basic
- steps that the "run" script executes:
-
- % setenv CLASSPATH ../..:$CLASSPATH
-
- % javac -d ../.. *.java
-
- % rmic -d ../.. examples.stock.StockServer examples.stock.StockApplet
-
- % java -Djava.security.policy=security.policy examples.stock.StockServer &
-
- % appletviewer index.html
-
- Note: you can set your CLASSPATH back to the old CLASSPATH (without
- ../.. in it) before running the appletviewer, so that classes get
- downloaded from the network rather than from your CLASSPATH; each of
- the scripts actually does this.
