<h1 class="topictitle1">Example: Running a Java applet using proxy support</h1>
|
||
|
|
<div><p>The following example shows you the steps to run a Java™ applet
|
||
|
|
using proxy support.</p>
|
||
|
|
<div class="section"><p> </p>
|
||
|
|
<ol><li>Choose a machine to act as the proxy server. Applets can initiate network
|
||
|
|
connections only to the machine from which they were originally downloaded;
|
||
|
|
therefore, it works best to run the proxy server on the same machine as the
|
||
|
|
HTTP server. The Java environment and CLASSPATH on the proxy server machine
|
||
|
|
includes the jt400.jar file.</li>
|
||
|
|
<li>Start the proxy server on this machine by typing: <samp class="codeph">java com.ibm.as400.access.ProxyServer
|
||
|
|
-verbose</samp> Specifying verbose will allow you to monitor when the client
|
||
|
|
connects and disconnects.</li>
|
||
|
|
<li>Applet code needs to be downloaded before it runs so it is best to reduce
|
||
|
|
the size of the code as much as possible. The <a href="jar.htm#jar">AS400ToolboxJarMaker</a> can
|
||
|
|
reduce the jt400Proxy.jar significantly by including only the code for the
|
||
|
|
components that your applet uses. For instance, if an applet uses only JDBC,
|
||
|
|
reduce the jt400Proxy.jar file to include the minimal amount of code by running
|
||
|
|
the following command:<pre> java utilities.AS400ToolboxJarMaker -source jt400Proxy.jar -destination jt400ProxySmall.jar
|
||
|
|
-component JDBC</pre>
|
||
|
|
</li>
|
||
|
|
<li>The applet must set the value of the com.ibm.as400.access.AS400.proxyServer
|
||
|
|
system property to be the name of your proxy server. A convenient way to do
|
||
|
|
this for applets is using a compiled Properties class (<a href="systempropertiessample2.htm#systempropertiessample2">Example</a>).
|
||
|
|
Compile this class and place the generated Properties.class file in the com/ibm/as400/access
|
||
|
|
directory (the same path your html file is coming from). For example, if the
|
||
|
|
html file is /mystuff/HelloWorld.html, then Properties.class is in /mystuff/com/ibm/as400/access.</li>
|
||
|
|
<li>Put the jt400ProxySmall.jar in the same directory as the html file (/mystuff/
|
||
|
|
in step 4).</li>
|
||
|
|
<li>Refer to the applet like this in your HTML file:<pre> <APPLET archive="jt400Proxy.jar, Properties.class" code="YourApplet.class"
|
||
|
|
width=300 height=100> </APPLET></pre>
|
||
|
|
</li>
|
||
|
|
</ol>
