This <code>.jar</code> contains classes which <em>must</em> be available to the client when it is run (they cannot be downloaded). Note that the proxy code in <code>blitz-dl.jar</code> will be downloaded as usual.</li> +</ul> + +Assuming that your JINI 2.x distribution is in <code>/jini2_1</code> and your Blitz distribution is in <code>/blitz</code>, you can compile the example as follows: + +<pre> +cd /blitz/examples/statsclient + +javac -classpath /jini2_1/lib/jsk-lib.jar:/jini/jini2_1/lib/jsk-platform.jar:/blitz/lib/stats.jar *.java +</pre> + +<h2>Running</h2> + +<p>Before starting the example, ensure that you have a Blitz instance running in a public lookup group - see the <a href="install_guide.html">Installation Guide</a>. This is necessary because the <code>Lookup</code> class does a single lookup and discover step - it does not register with discovered lookup services. Thus, if a Blitz instance isn't registered beforehand, it will not be found (I'll fix this in a future release!).</p> + +Having compiled the example, you can run it as follows (with the same assumptions about installation locations as above): + +<pre> +cd /blitz + +java -Djava.security.policy=config/policy.all -classpath /jini2_1/lib/jsk-lib.jar:/jini2_1/lib/jsk-platform.jar:/blitz/examples/statsclient:/blitz/lib/stats.jar stats.TestClient +</pre> + +<h2>Configuring Defaults</h2> + +In addition to passing an array of Switch objects to Blitz via the StatsAdmin interface, it's possible to configure default settings via the config file using an entry like: + +<pre> +// Default Stats to make available +stats = new Switch[] {new OpSwitch(OpSwitch.ALL_TYPES, OpSwitch.TAKE_OPS, true), + new OpSwitch(OpSwitch.ALL_TYPES, OpSwitch.READ_OPS, true), + new OpSwitch(OpSwitch.ALL_TYPES, OpSwitch.WRITE_OPS, true)}; +</pre> + +<p><div align="center"><a href="../index.html">Back to Documentation</a></div></p> +</body> +</html> \ No newline at end of file
