    text
    copied!<p>Every time I call a function of my applet from my Java Script, it throws an undefined exception. And my googling hasn't helped me at all.</p> <p>here is a link to the site I am am hosting it on right now: <a href="http://boba.dyndns-server.com:8080/BobaServer/CourseEntryPage.html" rel="nofollow">Host Site</a></p> <p>Here is my html for the embedding the Applet:</p> <pre><code>&lt;object type="application/x-java-applet" id="ClientApp" name="ClientApp" archive="Cal.jar" width="100" height="100"&gt; &lt;param name="code" value="Calendar_Algorithm" /&gt; &lt;param name="mayscript" value="true" /&gt; &lt;/object&gt; </code></pre> <p>And here is my java script code:</p> <pre><code>function test(){ document.writeln("&lt;p&gt; "+"Test"+" &lt;/p&gt;"); try{ var s=document.ClientApp.getGreeting(); document.writeln("&lt;p&gt; First: "+s+" &lt;/p&gt;"); }catch(err){ document.writeln("&lt;p&gt;Error Caught 1: "+err.description+"&lt;/p&gt;"); } try{ var s=document.getElementById('ClientApp').getGreeting(); document.writeln("&lt;p&gt; Second: "+s+" &lt;/p&gt;"); }catch(err){ document.writeln("&lt;p&gt;Error Caught 2: "+err.description+"&lt;/p&gt;"); } document.close(); } </code></pre> <p>I know it loads the applet because I can see the gui, and if it helps here is my init function</p> <pre><code>public void init() { try { SwingUtilities.invokeAndWait(new Runnable() { public void run() { JLabel lbl = new JLabel(getGreeting()); add(lbl); } }); } catch (Exception e) { System.err.println("createGUI didn't complete successfully"); } } </code></pre> <p>here is a link to my full code as well <a href="https://docs.google.com/document/pub?id=1PESG5iyav6mYzveLJK-lM2n2Grn4FmcN81lw8jZviZI" rel="nofollow">Code</a></p> <p>I got a feeling that the error is incredibly obvious, but I just can not see it.</p> <p>Any help would be great!</p> <p>P.S. The Applet class files are now in a signed jar file.</p> <p>Also This will be placed in the webapps folder of a tomcat server, but I am currently accessing it as a local file.</p>
