<h1 class="topictitle1">Install extensions for the IBM Developer Kit for Java</h1>
|
||
|
|
<div><p>Extensions are packages of Java™ classes that you can use to extend
|
||
|
|
the functionality of the core platform. Extensions are packaged in one or
|
||
|
|
more ZIP files or JAR files, and are loaded into the Java virtual
|
||
|
|
machine by an extension class loader.</p>
|
||
|
|
<div class="section"><p>The extension mechanism allows the Java virtual machine to use the extension
|
||
|
|
classes in the same way that the virtual machine uses the system classes.
|
||
|
|
The extension mechanism also provides a way for you to retrieve extensions
|
||
|
|
from specified Uniform Resource Locators (URLs) when they are not already
|
||
|
|
installed in the J2SDK, version 1.2 or higher or Java 2 Runtime Environment, Standard Edition,
|
||
|
|
version 1.2 and higher.</p>
|
||
|
|
<p>Some JAR files for extensions are shipped with
|
||
|
|
the iSeries™ server.
|
||
|
|
If you would like to install one of these extensions, enter this command:</p>
|
||
|
|
<blockquote><pre>ADDLNK OBJ('/QIBM/ProdData/Java400/ext/extensionToInstall.jar')
|
||
|
|
NEWLNK('/QIBM/UserData/Java400/ext/extensionToInstall.jar')
|
||
|
|
LNKTYPE(*SYMBOLIC)</pre>
|
||
|
|
</blockquote>
|
||
|
|
<p> Where</p>
|
||
|
|
<samp class="codeph">extensionToInstall.jar</samp><p>is
|
||
|
|
the name of the ZIP or JAR file that contains the extension that you want
|
||
|
|
to install. </p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> JAR files of extensions not provided by IBM<sup>®</sup> may be placed
|
||
|
|
in the /QIBM/UserData/Java400/ext directory.</div>
|
||
|
|
<p>When you create a link
|
||
|
|
or add a file to an extension in the /QIBM/UserData/Java400/ext directory,
|
||
|
|
the list of files that the extension class loader searches changes for <em>every Java virtual
|
||
|
|
machine that is running on your iSeries server</em>. If you do not want
|
||
|
|
to impact the extension class loaders for other Java virtual machines on your iSeries server,
|
||
|
|
but you still want to create a link to an extension or install an extension
|
||
|
|
not shipped by IBM with
|
||
|
|
the iSeries server,
|
||
|
|
follow these steps:</p>
|
||
|
|
</div>
|
||
|
|
<ol><li><span>Create a directory to install the extensions. Use either the Make
|
||
|
|
Directory (MKDIR) command from the iSeries command line or the <samp class="codeph">mkdir</samp> command
|
||
|
|
from the Qshell Interpreter.</span></li>
|
||
|
|
<li><span>Place the extension JAR file in the directory created.</span></li>
|
||
|
|
<li><span>Add the new directory to the java.ext.dirs property. You can add
|
||
|
|
the new directory to the java.ext.dirs property by using the PROP field of
|
||
|
|
the JAVA command from the iSeries command line.</span></li>
|
||
|
|
</ol>
|
||
|
|
<div class="section"><p> If the name of your new directory is /home/username/ext, the name
|
||
|
|
of your extension file is extensionToInstall.jar, and the name of your Java program
|
||
|
|
is Hello, then the commands that you enter should look like this:</p>
|
||
|
|
<blockquote><pre>MKDIR DIR('/home/username/ext')
|
||
|
|
|
||
|
|
CPY OBJ('/productA/extensionToInstall.jar') TODIR('/home/username/ext') or
|

|
|
copy the file to /home/username/ext using FTP (file transfer protocol).
|
||
|

JAVA Hello PROP((java.ext.dirs '/home/username/ext'))</pre>
