java.lang.InstantiationException: either code or object should be specified, but not both


Symptoms

When running an applet in a browser using the Sun Java Runtime Environment (JRE) implementation, a java.lang.InstantiationException is thrown. The same applet runs without any errors with the Microsoft  Virtual Machine (VM).

Cause

There are two possible causes.

Resolution

        In the first cause eliminate the code attribute in the <APPLET> tag as shown in the following code:

             <APPLET object=MyApplet.ser width=100 height=100>
             </APPLET>

        In the second cause change the parameter name to a different name as shown in the following code:

             <APPLET code=MyApplet width=100 height=100>
             <PARAM name="property1" value="someValue">
             </APPLET>

             public class MyApplet extends java.applet.Applet
             {
                 public void init()
                 {
                         String value = getParameter("property1");
                 }
                 ....
             }
