Stock Example Using RMI

The docs/guide/rmi/examples/stock directory in the JDK 1.1 Beta installation 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/classes for this example are as follows:

On Solaris, after downloading the JDK 1.1 Beta release, execute the run script in the docs/guide/rmi/examples/stock directory, which will print out what it is doing while it runs the example. The stock server creates its own registry, so the "rmiregistry" does not need to be started. Here are the basic steps that the run script executes:

  1. setenv CLASSPATH ../..:$CLASSPATH
  2. javac -d ../.. *.java
  3. rmic -d ../.. examples.stock.StockServer examples.stock.StockApplet
  4. java examples.stock.StockServer &
  5. 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 via the network rather than via CLASSPATH; each of the scripts actually does this.

On Windows systems, after downloading the JDK 1.1 Beta release, 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.
