Hi Fedora,<br> <br>     I need your help.<br><br>     I Setup the Eclipse IDE &amp; Tomcat server on Fedora 9. I am facing following problems while enabling graphical APIs on the application:<br><b>1</b>. I have a running java application with JCharts on Windows which works fine with Eclipse &amp; Tomcat server. But when I am  trying to deploy the same on Fedora 9. JCharts are not able to render &amp; I am getting the following error:<br>
    : &quot;<i><b style="color: rgb(255, 0, 0);">Gtk Warning: cannot open display</b></i>&quot;. <br>If I disable the call to JCharts APIs, My application works fine. Can you please help me here.<br><br><b>2</b>. To overcome this issue, I move to another Chart API: JFreeCharts. I added the jar in the classpath &amp; also added its java files in the project, but whenever I am running my application from Eclipse with Tomcat, Tomcat is not able to  load this JFreeChart class files, saying : <pre style="color: rgb(255, 0, 0);">
<b>java.lang.NoClassDefFoundError</b></pre>. Please help me here.<br><br><br>Thanks<br>David.<br>
