Why the browser cannot run the applet when the appletviewer can ?

Why the browser cannot run the applet when the appletviewer can ?

i have an simple Class file in the directory c:\cdir\named.class
and am having a HTML file in c:\named.html with code="cdir.named"
when i run the file as appletviewer named.html it shows the applet but when
i open the same html file from other browser it shows me the following error.

Applet cdir.named can't start error:java.lang.ClassFormatError

The Console reads as follows

in the <applet>-tag of the HTML-code it should say :
CODEBASE="c:/cdir/" CODE="named.class"

if the HTML- and class-files are in the same library, you can use :
CODEBASE="." CODE="named.class"
