      <itunes:summary>&lt;p&gt;I suggest you contact Maplesoft &lt;a href="http://www.maplesoft.com/support"&gt;Tech support&lt;/a&gt;. It sounds like there may be a problem with your MapleNet installation. The below plot:&lt;/p&gt;
&lt;p&gt;&lt;img class="plot" src="http://www.mapleprimes.com/MapleImage.ashx?f=204989c87314c9e8bfb603df4ceed95a.gif" alt="plot3d(x^2+y^2,x=-1..1,y=-1..1)"&gt;&lt;/p&gt;
&lt;p&gt;Is generated using MaplePrimes' installation of MapleNet using the same imaging method you are using. So it appears there is something wrong with your installation.&lt;/p&gt;

      <itunes:summary>&lt;p&gt;Tech support told me how to fix the problem.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I am using Tomcat that is installed originally with Mac OS X Server 10.6.&lt;/p&gt;
&lt;p&gt;There seems to be a problem with 64bit version of jvm.&lt;/p&gt;
&lt;p&gt;In order to fix the problem, /Library/Tomcat/bin/startup.sh should be rewitten as follows;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;exec "$PRGDIR"/"$EXECUTABLE" start "$@"&lt;/p&gt;
&lt;p&gt;-&amp;gt;&lt;/p&gt;
&lt;p&gt;export JAVA_OPTS=-d32&lt;/p&gt;
&lt;p&gt;exec "$PRGDIR"/"$EXECUTABLE" start "$@"&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Thank you for Tech support !&lt;/p&gt;</itunes:summary>
