<h1 class="topictitle1">Configuring NAWT environment variables</h1>
|
|
<div><p>Any time that you run Java™ with NAWT, you must set environment
|
|
variables that tell Java the system name, the display number,
|
|
and where to find each X server and the associated .Xauthority file.</p>
|
|
<p><strong>Note:</strong> Starting the Virtual Network Computing (VNC) server determines
|
|
the location of the .Xauthority file and the values for the system name
|
|
and display number. You need to use these values to successfully configure
|
|
the NAWT environment variables. For more information, see <a href="nawtstartvncserver.htm">Starting
|
|
the Virtual Network Computing server</a>.</p>
|
|
<div class="section"><h4 class="sectiontitle">Configuring DISPLAY</h4><p>In the session where you want
|
|
to run Java programs, set the DISPLAY environment variable
|
|
to your system name and display number. To configure the DISPLAY environment
|
|
variable, at an <span class="keyword">i5/OS™</span> command
|
|
line, type the following control language (CL) command and press <strong>ENTER</strong>:</p>
|
|
<pre> ADDENVVAR ENVVAR(DISPLAY) VALUE('<em>systemname:n</em>')</pre>
|
|
<p>where <em>systemname</em> is the host name or IP address of
|
|
your iSeries™ system
|
|
and <em>n</em> is the display number of the VNC server.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Configuring XAUTHORITY</h4><p>Also, set the XAUTHORITY
|
|
environment variable to <kbd class="userinput">/home/VNCprofile/.Xauthority</kbd>,
|
|
where <em>VNCprofile</em> is the profile that started the VNC server.</p>
|
|
<p>For
|
|
example, at the iSeries command
|
|
prompt, type the following commands:</p>
|
|
<pre> ADDENVVAR ENVVAR(DISPLAY) VALUE('<em>systemname:n</em>')
|
|
ADDENVVAR ENVVAR(XAUTHORITY) VALUE('/home/<em>VNCprofile</em>/.Xauthority')</pre>
|
|
<p> Where:</p>
|
|
<ul><li><em>systemname</em> is the host name or IP address of your iSeries system.</li>
|
|
<li><em>n</em> is the display number of the VNC server.</li>
|
|
</ul>
|
|
<p> <strong>Notes:</strong></p>
|
|
<ul><li>You need to set these environment variables only in the environment where
|
|
you will run the Java virtual machine (JVM).</li>
|
|
<li>When you cannot run the VNC server and the Java virtual machine under the same
|
|
user profile, you can configure XAUTHORITY to point to the appropriate
|
|
.Xauthority file. You must ensure that the other profiles under which the
|
|
JVM runs can access the .Xauthority file. For more information, see <a href="nawtstartvncserver.htm">The .Xauthority file</a>.</li>
|
|
<li>The XAUTHORITY security mechanism is different from the VNCPASSWD security
|
|
mechanism. Both protection schemes are necessary for secure graphics
|
|
rendering. For more information about VNCPASSWD, see <a href="nawtcreatevncpassword.htm">Creating
|
|
a VNC password file</a>. </li>
