> ## `java.lang.InstantiationException`: Either "code" or "object" should be specified, but not both.

> ###
> Symptoms

> > When running an applet in a browser using the Sun JRE, an `InstantiationException` is thrown. The same applet runs under the Microsoft VM.

> ### Cause

> > There are two possible causes.

> > 1. Both `code` and `object` attributes are specified in the `<APPLET>` tag:
> >    `<APPLET code=MyApplet object=MyApplet.ser width=100 height=100>`
> >    `</APPLET>`
> >    The Sun JRE can access either the `code` or the `object` attribute, but not both.
> > 2. A `code` attribute is specified in the `<APPLET>` tag, and an `object` attribute is specified in a `<PARAM>` tag :
> >    `<APPLET code=MyApplet width=100 height=100>`
> >    `<PARAM name="object" value="someValue">`
> >    `</APPLET>`
> >    `public class MyApplet extends java.applet.Applet`
> >    `{`
> >    `public void init()`
> >    `{`
> >    `String value = getParameter("object");`
> >    `}`
> >    `....`
> >    `}`
> >    The Sun JRE does not support `object` as a parameter name.

> ### Resolution

> The workaround in the first case is to eliminate the `code` attribute in the `<APPLET>` tag:
> `<APPLET object=MyApplet.ser width=100 height=100>`
> `</APPLET>`
> The workaround in the second case is to change the parameter name to a different name:
> `<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");`
> `}`
> `....`
> `}`
