    <p>For a programming assignment, I am trying to have a GlassFish server serve up a client applet to talk to the server servlet. I've been stuck on having GlassFish deliver the applet. I have been searching extensively on this, and am not finding anything that resolves the issue - though I am learning quite a bit.</p> <p>I have a 'hello world' applet compiled to tskApplet.class. </p> <pre><code>import java.applet.Applet; import java.awt.*; public class tskApplet extends Applet { public void paint (Graphics g) { g.drawString("Hello world! It's an applet!", 5, 25); } } </code></pre> <p>I have an html page that loads the applet with the following applet tag:</p> <pre><code>&lt;applet code = "tskApplet.class" width="300" height="300"&gt;&lt;/applet&gt; </code></pre> <p>I've tried (to no avail) all sorts of variations such as putting the .class file in a .jar and including archive="tskApplet.jar" in the applet tag, and using a .jsp page, etc.</p> <p>I'm using IntelliJ and if I run the tskApplet from an applet run/debug configuration it works fine. I followed this guide to set up GlassFish with ImtelliJ: <a href="http://wiki.jetbrains.net/intellij/Developing_applications_for_GlassFish_Server_in_IntelliJ_IDEA" rel="nofollow">http://wiki.jetbrains.net/intellij/Developing_applications_for_GlassFish_Server_in_IntelliJ_IDEA</a></p> <p>If I copy the exact same .class file and .html file from the GlassFish server's web directory to the OS X Sites folder, then the applet works fine from the browser when I access it that way.</p> <p>But if I run GlassFish and access my web application, the applet does not run. Instead I get these errors in the browser java console:</p> <pre><code>java.lang.ClassFormatError: Incompatible magic value 1768779887 in class file tskApplet at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632) at java.lang.ClassLoader.defineClass(ClassLoader.java:616) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at sun.plugin2.applet.Applet2ClassLoader.findClass(Applet2ClassLoader.java:219) at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Plugin2ClassLoader.java:249) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Plugin2ClassLoader.java:179) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Plugin2ClassLoader.java:160) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Plugin2ClassLoader.java:674) at sun.plugin2.applet.Plugin2Manager.createApplet(Plugin2Manager.java:2990) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Plugin2Manager.java:1481) at java.lang.Thread.run(Thread.java:680) </code></pre> <p>Any suggestions where to look next?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
