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 is the remote interface for stock server.

• StockNotify is the remote interface for stock observer.

• Stock is the 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) exports a remote object (itself), registers with StockServer for stock updates, and displays stock notifications as they are received.

On Windows systems, after downloading the Java^TM 2 SDK, execute run.bat in the docs/guide/rmi/examples/stock 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 Solaris, after downloading the Java 2 SDK, 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 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.
