java.lang.InstantiationException: Either "code" or "object" should be specified, but not both.
SymptomsWhen running an applet in a browser using the Sun JRE, an
InstantiationExceptionis thrown. The same applet runs under the Microsoft VM.Cause
There are two possible causes.
- Both
codeandobjectattributes are specified in the<APPLET>tag:
<APPLET code=MyApplet object=MyApplet.ser width=100 height=100>
</APPLET>
The Sun JRE can access either thecodeor theobjectattribute, but not both.
- A
codeattribute is specified in the<APPLET>tag, and anobjectattribute 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 supportobjectas a parameter name.Resolution
The workaround in the first case is to eliminate the
codeattribute 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");
}
....
